Introducing CSS FilterLab

In October 2011, Adobe proposed CSS Shaders as a way to bring cinematic effects to the web. Effects like saturation, gamma, burn, fold, curl, and even dissolve and explode could be applied with CSS to regular HTML elements. That proposal has evolved. It has been openly debated, updated, and merged with the CSS Filter Effects specification. It is now on its way to a browser near you. CSS Shaders now go by the name of CSS Custom Filters but they’re just as expressive.

CSS FilterLab

CSS FilterLab is a browser-based tool that lets you play with CSS filters, tweak them, and see the effects in real time (see Figure 1). You can use the tool to combine multiple filters and animate them to create rich cinematic effects.

Figure 1. Creating and applying filters in CSS FilterLab.
At the time of writing, this is really cutting-edge technology, so only a few browsers support it. So, when you open up CSS FilterLab in your browser, you’ll be prompted with instructions on what to do to get the best experience. We took great care to make those instructions simple and easy to follow.

Getting started

It’s easy to start experimenting with CSS FilterLab. Once you open it up in a browser, you can start adding filters from the Add Filter menu.

You can choose to apply built-in filters or custom filters:

Built-in filters are the ones that come by default with the browser. They bring basic color effects such as grayscale, sepia, saturation or contrast.
Custom filters take effects to a whole new level. Some examples that have been built include effects like burn, curl, fold, dissolve, explode, and many more. Custom filters don’t come with the browsers; they’re written by developers themselves. They make use of shaders, which are small programs that enable fine-grained control over color and geometry. Shaders take advantage of hardware acceleration and are commonly used in visual effects for gaming. They might look alien to CSS developers, and they generally require a strong grasp of math.
Fortunately, CSS FilterLab comes bundled with a few great examples of custom filters with underlying shaders. One such example is Fold, which gives an HTML element the 3D aspect of a folded piece of paper (see Figure 2).

Figure 2. The Fold custom filter applied to the HTML element in CSS FilterLab.
The filters that have been applied expose their parameter controls. This makes it very easy for you to fine-tune them to get the effect you’re looking for. In addition, multiple built-in and/or custom filters can be applied together to get stunning results.

Once you’re happy with the result, save your changes as a preset. This allows you to reuse the configuration later.

Animating effects

Effects don’t just happen. They come into being, transitioning from one state to another. This is what makes them expressive.

CSS FilterLab comes with a basic set of animation controls that help you create smooth transitions between filter parameter values.

Notice the timeline and controls at the bottom of the screen. Click at any point of the timeline, and then change the parameters of the active filters. This creates a new keyframe on the timeline. Hit the play button to see the animation run through (see Figure 3).

Keyframes can be added, dragged around the length of the timeline or removed so you can tweak the animation to get it just right.

The duration of the animation can be changed from the input to the right of the timeline. It’s measured in seconds.

Code syntax

CSS FilterLab enables you to create rich visual effects. It’s important to know that this is done with plain CSS, albeit cutting-edge CSS.

At Adobe, we’ve worked hard, together with our partners, to bring this technology to the open web. We’re not about to hide it behind a tool.

CSS FilterLab shows the exact code that’s being used to achieve an effect or animation. The CSS Syntax and CSS Animation Syntax panels, just above the timeline, show just what you’d expect. You can copy this code into your own projects to make use of the effects. Keep in mind that CSS Filters are just starting to become available in browsers.

Creating new custom filters

This is where things can become challenging. However, if you find complex math and writing shaders particularly appealing, you’ll be glad to know that CSS FilterLab includes a fully-fledged shader editor (see Figure 4).

To create a new custom filter, start by forking an existing custom filter from the ones provided under the Add Filter menu. You’ll notice that your forked filter appears in the Forked tab of the menu. Click the “customize” icon and you’ll get to the core of a custom filter.

From this point on, you have full control over the parameters used, their types, as well as the fragment and vertex shader source. Your changes are automatically saved and stored locally, in the browser.

Shaders are written in OpenGL Shading Language (GLSL). The topic of writing shaders is beyond the scope of this introduction, but you can learn more from the GLSL documentation. Be sure to read about the types, methods, and features of the language to get the best out of your shaders.

Figure 3. The error panel highlights issues.
The error panel highlights any issues with your shader code, in real time. This is really useful because it keeps you in the same context while developing and previewing. You also get to see the results of your shader code in real time.

Sharing and importing custom filters

Share your custom filters by publishing them from CSS FilterLab as a gists on GitHub. The controls for doing this are found in the shader editor panel.

Once published, share the link with others. They’ll be able to import your custom filter in CSS FilterLab and use it on their own content. To import a custom filter go to the Add Filter menu, choose Import and use the gist URL.

Open source

All of the code for CSS FilterLab is freely available on GitHub under the Apache License v2. We’re looking forward to your thoughts, feedback, and contributions to the project.

If you write shaders that you’d like to distribute with CSS FilterLab, please contribute them to the project. Before checking in any code, take a moment to make yourself familiar with the contribution guidelines outlined on GitHub.

Where to go from here

CSS Filters and Custom Filters open up a wealth of creative effects for web content. CSS FilterLab gives only a hint about what’s becoming possible. But the true value is in your hands and in what you create with this technology.

Give some thought to the new opportunities for interaction and expressiveness that filters, geometry manipulation and cinematic effects can bring to your work. Think about what this means for your content on a large screen, on a mobile device, and in so many new contexts.

Use CSS FilterLab to learn about the capabilities of the modern graphical web and share your thoughts with us. We’d love to know what you create with them.

Adobe’s Alan Greenblatt has created a short video walkthrough of CSS FilterLab. If you’re keen to learn more, that is a great place to start.

Set Text on a Circle – CSS Tricks

by: Chris Coyier


There isn’t any super simple standardized way to set web type on a circle (or any kind of curve). But it can be done! We’ll explore one way to do it here. But be forewarned, we’re going to use some CSS3 and JavaScript and not give two hoots about older browsers that don’t support some of the required tech. If you’re interested in this for a real project, this kind of thing is probably still best served by and image with proper alt text, or proper feature detection which can flip out the image for this fancy technique in browsers that can handle it.

An Example

View Demo   Download Files   Go Play on CodePen

Let’s proceed with something a bit simpler.

The Entire Process

Let’s take simple phrase for example:

Imagine if we took the words we were trying to set in a circle and broke them apart into individual letters.

Let’s make sure each box is the same exact size by using a monospace font.

Now let’s make each of those boxes long, like a bicycle wheel spoke.

Then we bundle up all those spokes so they are all right on top of each other.

Now imagine we afix the ends of those spokes to a central hub. We rotate each spoke just a little bit more than the last one.

If we rotate the parent element counter-clockwise and remove our red guides, we have some text on a circle!

Technical Bits

To be able to manipulate each letter like that, you have to wrap them in another element.Lettering.js can do that for you easily (jQuery and plugin dependency).

So you have this.

<h1>Established 2012</h1>

You load jQuery and Lettering.js and then call this:


And it turns into this in the DOM:

<h1> <span class="char1">E</span> <span class="char2">s</span> <span class="char3">t</span> <span class="char4">a</span> <span class="char5">b</span> <!-- you get the idea --> </h1>

This really only works well with monospaced fonts. Even if you force monospaced-ness by setting each span to a fixed with, the space between each letter will be wrong and it will look weird. You could manually kern it by manually adjusting each rotation if you were nuts.

For each span, you want to set the height, position them all in the same spot, and then set the transform-origin to the bottom of the box (so they rotate around that hub. Vendor prefix that).

h1 span { font: 26px Monaco, MonoSpace; height: 200px; position: absolute; width: 20px; left: 0; top: 0; transform-origin: bottom center; }

Now you need a whole bunch of class name selectors, each that rotates by a bit more.

.char1 { transform: rotate(6deg); } .char2 { transform: rotate(12deg); } .char3 { transform: rotate(18deg); } /* and so on */

But imagine that with every vendor prefix as well, pretty messy. With Sass and Compass it’s a three-liner:

@for $i from 1 through 100 .char#{$i} +transform(rotate(($i*6)+deg))

Taking things a bit further, we could get a little more finicky and fancy:

Or how about setting text on a spiral?


Here’s a Sass (.sass) mixin from Chris Eppstein for a more extensible text rotation mixin:

=rotated-text($num-letters: 100, $angle-span: 180deg, $angle-offset: 0deg) $angle-per-char: $angle-span / $num-letters; @for $i from 1 through $num-letters .char#{$i} +transform(rotate($angle-offset + $angle-per-char * $i))

CSS3 – Gradients

Speed Up with CSS3 Gradients


Safari 4+, Chrome 1+, Firefox 3.6+, and Opera 11.10+ are all now supporting CSS3 gradients. This wide browser support makes using them for progressive enhancement all the more appealing. More good news, CSS3 gradients fall into the camp where you can specify fallbacks (i.e. images) so that browsers that don’t support them just use the image instead.

But wait… if you need to use an image anyway, why bother with declaring the gradient with CSS? That is kind of how I felt for a long time, but there is one important aspect that makes it worth it:browsers that support them don’t load the image fallback. One less HTTP Request = all the faster your site will load.

How it’s done

Cutting to the chase, here is the CSS for the most simple possible top-to-bottom linear gradient:

.gradient-bg { /* fallback/image non-cover color */ background-color: #1a82f7; /* fallback image */ background-image: url(images/fallback-gradient.png); /* Safari 4+, Chrome 1-9 */ background-image: -webkit-gradient(linear, 0% 0%, 0% 100%, from(#2F2727), to(#1a82f7)); /* Safari 5.1+, Mobile Safari, Chrome 10+ */ background-image: -webkit-linear-gradient(top, #2F2727, #1a82f7); /* Firefox 3.6+ */ background-image: -moz-linear-gradient(top, #2F2727, #1a82f7); /* IE 10+ */ background-image: -ms-linear-gradient(top, #2F2727, #1a82f7); /* Opera 11.10+ */ background-image: -o-linear-gradient(top, #2F2727, #1a82f7); }

You could add the non-prefixed version too, but since that’s not yet supported in anything I typically opt out of that, in case there are last minute changes to spec.

And once more with better formatting and without the comments:

.gradient-bg { background-color: #1a82f7; background-image: url(images/fallback-gradient.png); background-image: -webkit-gradient(linear, 0% 0%, 0% 100%, from(#2F2727), to(#1a82f7)); background-image: -webkit-linear-gradient(top, #2F2727, #1a82f7); background-image: -moz-linear-gradient(top, #2F2727, #1a82f7); background-image: -ms-linear-gradient(top, #2F2727, #1a82f7); background-image: -o-linear-gradient(top, #2F2727, #1a82f7); }

CSS3 Please! is a good resource for snagging up-to-date syntaxes as well.

View Demo   Download Files

Different syntax for different rendering engines

Mozilla (Firefox, Flock, etc)

Mozilla’s syntax (more detail here) is like this:

-moz-linear-gradient([<point> || <angle>,]? <stop>, <stop> [, <stop>])

The simplest way to declare a gradient is to just list a comma separated list of colors. That will start at the top and gradient to the bottom with equidistant color stops for each color. In the demo code above, we use a point and an angle (90deg) to it go bottom-to-top instead. For radial gradients: -moz-radial-gradient

WebKit (Safari, Chrome, etc)

WebKit’s syntax (more detail herefor Chrome 1-9 and Safari 4-5 is like this:

-webkit-gradient(<type>, <point> [, <radius>]?, <point> [, <radius>]? [, <stop>]*)

They have now deprecated the old syntax and moved toward something simpler. As of Chrome 10 and Safari 5.1 it’s now like this:

background-image: -webkit-linear-gradient([<point> || <angle>,]? <stop>, <stop> [, <stop>]); /* Chrome 10+, Saf5.1+ */


As of Opera 11.10, Opera supports CSS3 gradients in the same format as Mozilla and the latest WebKit.

background-image: -o-linear-gradient([<point> || <angle>,]? <stop>, <stop> [, <stop>]); /* Opera 11.10+ */

Trident (IE)

Trident’s syntax (not really CSS3… more detail here) is like this:

filter: progid:DXImageTransform.Microsoft.gradient(GradientType=0, startColorstr=#1471da, endColorstr=#1C85FB); -ms-filter: "progid:DXImageTransform.Microsoft.gradient (GradientType=0, startColorstr=#1471da, endColorstr=#1C85FB)";

“filter” should work in IE6-IE8 (haven’t tested IE9), but it’s not “valid” code. “-ms-filter” is valid, but only works in IE8+.

Unfortunately, we can’t invite IE to the party! Using these filter properties does indeed work, and it would allow us to programmatically declare gradients which is cool. But, instead of using the filter first and the image as a fallback, declaring a background-image overrides the filter and it uses that. Since we definitely still need image fallbacks, we might as well not use this at all.

If you don’t need image fallbacks (just a solid color will do), using filter probably is a good idea.

Reader Ed Lerner writes in to say that even though filters only work with hex values, you can still get alpha transparency by prefacing the hex value with the amount of transparency from 00 (0%) to FF (100%). Example:

rgba(92,47,90,1) == #FF5C2F5A
rgba(92,47,90,0) == #005C2F5A


The WebKit and Mozilla syntax for gradients both incorporate “stops”. A stop is an optional additional declaration that includes a point and a color. This means the gradient wont just start at one color and end at the other, it will fade to the stop color first, and that stop color will fade to the end color. More than one stop can also be used.

Saving HTTP requests

Using Firebug and looking in the Net tab to see all the resources used by the page, we can see the advantage.

The above screenshot is Firefox 3.6. We can see that the gradient fallback images are NOT loaded, which saves an HTTP request.

However using Firefox 3.5.8, the fallbacks are loaded.

We don’t save any HTTP Requests in olders version of Firefox (This is 3.5.8 on Vista). The gradient fallback images are still being loaded (and used).

It gets a little more iffy in WebKit browsers.

WebKit browsers WILL use the CSS3 property to render the gradient, but at the same time, still load the fallback images, so no HTTP requests are saved. The only advantage is the programatic declaration of color.

UPDATE (August 9th, 2010)
As of this date, Safari 5.0.1 is still loading the fallback images, but Chrome 6.0.472.25 dev now joins the party of browsers that (awesomely) don’t load the fallback image.

UPDATE (April 1st, 2011)
Safari is at 5.0.4 and is still loading fallback images. Opera 11.10 does the right thing out of the gate by not loading fallbacks.

UPDATE (July 20th, 2011)
Safari 5.1 no longer loading fallbacks =)

Doing it by the numbers

The speed gained by losing an HTTP request, to me, is the biggest advantage. The more I learn about web performance it seems to me keeping those down is the #1 way to improve page load time. However there is another advantage to using CSS3 gradients, and that is that these gradients are created programmatically through numbers. Need to adjust some colors? Just adjust some numbers. No need to bring a big image editing program into the picture. This makes maintaining the site easier, as well as opens up doors for adjusting values on-the-fly. I imagine JavaScript libraries will begin to get the ability to animate these values soon enough, which will be pretty darn cool.

Ooooh Stretchy

When using an image for a gradient, it is declared as a CSS background-image and then repeated (you can often get away with a 1px slice, which is very efficient, size wise). The result though is that a static portion of the background is gradientized, and any overflow to that is flat color. Sometimes that works perfectly. Sometimes though it would be cool if the gradient stretched the entire height or width of the box. That is another thing CSS3 gradients can possibly be useful for:

So the big question is… is it really worth doing right now?

My answer on March 2nd, 2010: I’m thinking it’s pretty darn close. If the numeric representation is a big deal to you, then I say yes you should start using them. If the speed is the only reason you would, then just realize that the only browser that it will help in is Firefox 3.6+, so you might wanna wait a bit on that.

My answer on April 1st, 2011: Pretty much yes, go for it, especially linear gradients. Linear gradients are more solid cross browser and browsers that don’t support them are dropping in usage relatively quickly. Of course it depends on the exact use case, but typically a gradient is a visual nicety and thus a fallback of a solid color or image isn’t such a big deal.

Wire Frame – Web

Library Site Design: Wireframes


Nov18by Thanks – Joseph Gilbert

Our design principles for the Library site restructuring left us with a lot of tricky design issues to tackle, and we also needed to make sure we were addressing organizational stakeholder needs in addition to our researched user needs.  Reviewing the ways that other websites approach similar problems proved informative (such as those in eduStyle’s Noteworthy Sites list), though most other library sites contained the same complex, tabbed search boxes, obscure navigational labeling, and physical location focus that we hoped to avoid.  After many conversations with Erin, reviewing organizational needs based on Erin’s interviews, considering our user personae, and studying our analytics data, I produced the following wireframes and presented them to our stakeholder community (Nov. 16, 2011).


Library Home Wireframe

The home page design has obvious paths for the “library as research hub” and “library as service space” user populations, a streamlined four-item main navigation (replacing a building-based navigation), content for first-time or curious users, and a cross-cutting series of “utility” navigation menus in the footer.

Home (with menu)

Library Home with Menu

“About the Library” employs a “mega-menu” that helps us structure content in ways that a traditional drop-down menu does not. Here, we guide most users to their likely destination of “Libraries & Labs”.

Libraries & Labs

Libraries & Labs Wireframe

The Libraries & Labs page puts the focus on space vitals (like hours and contact info) while allow each space to embed a blog feed or similar content for space-specific and time-sensitive user communication. The user is able to filter spaces by certain criteria, such as which libraries are open.

 Exhibits & Collections

Exhibits & Collections Wireframe

The Collections page puts a strong, renewed emphasis on our named and thematic collections, per our design principles, to encourage not only easy access by our local research community, but also visibility to scholars and enthusiast around the world.


Services Wireframe

The Services page meets our design principle goal of providing cross-organizational access to services. The hierarchical headings help us avoid a “laundry list” approach to services while still highlighting the breadth and depth of expertises offered by the Library.

Our Organization

Organization Wireframe

The “Our Organization” page, replacing departmental listings, gives users (more likely to be at other university libraries or prospective employees than our local students) to get the same sense of activity and personality that our Libraries & Labs page employs for those units not linked directly to physical spaces.



Hot in web standards: May 2012

Hot in web standards: May 2012

By Lea Verou on May 31, 2012 | 3 comments

In the first of a regular series of reports, Lea Verou summarises the latest need-to-know developments in the fast-moving world of the Working Groups …

May 2012 brought many exciting developments in web standards, across a number of different Working Groups. Here, in the first of a regular series of reports, I’ll sum up the hottest topics and emerging trends every professional web designer needs to know about. If any of the concepts seem unfamiliar, you can might want to begin by reading the 8 biggest web standards myths, debunked. Otherwise, let’s get started!


Blending modes and filters are coming to CSS

Ever wanted to blur an HTML element? Greyscale its contents? Use Photoshop-style blending modes on it, like “Multiply”? There are two new proposals that do exactly this:

These are not entirely new concepts, they have been possible in SVG for a long time. However, these new specifications bring those effects to HTML content as well. In addition, they are introducing a couple of simple shortcuts, that eliminate the need of linking to an SVG file that contains the effects. For example, to blur an element, you simply do:

  1. filter: blur(10px);

Filters also solve the common problem with CSS box-shadows which don’t follow the transparency of the element, but are always rectangular (see image). CSS filters can produce true drop shadows that fully follow the form of the element, accounting for non-solid borders, semi-transparent fills, pseudo-elements etc. You can play with a dabblet comparing the differences here.


Blending modes are equally simple to apply: 

  1. blend-mode: multiply;

There are going to be ways to selectively apply blending modes to parts of the element, such as only the background or shadows, but the syntax for this is still under discussion.

Filters are already supported by Chrome (behind a -webkit- prefix), so you can experiment with them all you want. Blending modes are newer and have no implementations yet. However, once they get a few implementations you can start using them immediately, as they both degrade quite gracefully.

Both specs are developed in the FX task force (FX TF), which is a joint effort between theCSS WG and the SVG WG. The FX TF focuses on developing new specifications that apply to both CSS and SVG as well as merging and simplifying existing technologies that could apply to both (such as transforms).

The responsive images saga

“Responsive images” is a term used to describe a number of approaches to conditionally load different image files on an <img>, based on the capabilities of the client (eg screen size, pixel density etc).

Lately, there has been a lot of discussion around standardising responsive images. After a misunderstanding in the WHATWG mailing list, a group of developers formed a W3C Community Group to discuss the issue. After a lot of back and forth, they decided that the best solution would be a <picture> element, containing one or more <source> elements, as well as an optional fallback (eg an <img>). One of the biggest benefits of this approach is consistency, as it’s on par with other HTML5 media elements, such as <video> and <audio>. According to most authors, it’s also a more elegant and easy to understand syntax.

Unfortunately, it turned out that, despite the aforementioned benefits, their proposed solution was harder to implement as it conflicts with the work performed by the lookahead pre-parser, a technique employed by every rendering engine to download assets faster, before even proper parsing of the content. In addition, it was advocated that media queries are not the best way to select which assets to load. For example, if we have an iPhone 4 Retina display with a high pixel density, but said iPhone is currently on a data roaming internet connection that costs €3/MB, do we load high- or low-res images? Media queries won’t help here and as someone who uses data roaming a lot, I don’t think such use cases are negligible.

For these reasons, WHATWG settled on a srcset attribute instead. A lot of author outragefollowed that news, but at the time of writing, WHATWG is still reluctant to reverse their decision. Furthermore, rumours are circulating that Apple has already implemented srcset in WebKit, pushing WHATWG towards it.


There’s been a big spat over responsive images but WHATWG is unwilling to reverse its decision

CSS Alignment module

In the past few years, it became clear that CSS layout was lacking. Floats and CSS tables were not built for laying out web applications. To deal with this, the CSS WG authored a number of different layout modules, such as Flexbox and Grid Layout.

These new modules are finally on par with the layout managers traditionally used in native applications. However, fantasai noticed that they each introduced different mental models and syntax for alignment, even though this could be shared across all layout-related CSS modules. To rectify this, she started a new draft that attempts to merge all these different models into one: CSS Box Alignment Module Level 3. It’s still at a very early stage, but it’s showing a lot of promise.

Flexbox is on its way to Last Call, a milestone that will also incorporate the new alignment properties.

CSS prefixes, again

A few weeks ago, Opera’s leaked decision to actually implement some -webkit- featuresstirred the CSS prefixes drama again. The issue is multi-faceted and it could even be said that it’s one of the worse situations the CSS WG has ever faced. The main problem is that every proposed solution suffers from at least two of the following four problems:

  1. Does not allow the CSS WG to get enough author feedback on experimental features (eg constraining experimental features only in non-stable browser builds)
  2. Does not allow the CSS WG to change the features because any change will break too many existing websites (the current situation)
  3. Does not allow authors to target specific implementations, which is a problem since experimental implementations can (and should) be vastly different (dropping the prefixes falls in this category)
  4. If authors are allowed to target specific implementations in an opt-in fashion, they don’t handle it responsibly, turning the system into a popularity contest (the current situation).

At the moment, it seems almost impossible to find a holy grail solution that will address all of the above. Florian Rivoal from Opera took a shot at it, with a proposal that gained some traction, as it almost eliminates both #3 and #4. Unfortunately, it still suffers from issue #2, so it was rejected.
