Stretchy: Form element autosizing, the way it should be

As you might be aware, these days a good chunk of my time is spent working on research, at MIT . Although it’s still too early to talk about my research project, I can say that it’s related to the Web and it will be open source, both of which are pretty awesome (getting paid to work on cool open source stuff is the dr.

An album for a11y

TL;DR I'm putting together an album to raise money for an organization that supports web accessibility. I had this brainwave while nursing a hangover in Brighton after Responsive Day Out: There are a load of folks working in the overlapping fields of web standards and accessibility who are musicians. Some really quite.

The Precarious X In UX

I have a long-held suspicion of anything directed at me — especially anything commercial — that sells itself on its "experiential" qualities. I hate the word "immersive" in particular. "Here, let me waterboard you with my new web app! You're going to love it!" Basically, I'm suspicious of anything that seeks to appeal.

Frame Based Animation With Sass

Frame Based Animation with Sass I wanted an easy way to create traditional animations, wherein each frame is a different drawing. I created this Sass @mixin which generates keyframe animation blocks for nth children, placing each of these "frames" in an animated sequence. Note the use of the steps(1) timing function&h.

The role of the Front-end Developer

The role of the front-end developer extends far beyond translating designs into code. They should be involved in many other aspects of the design and development process too.

Select boxes shouldn’t submit on change

Some forms that let users sort a list sometimes consist of single select box without a submit button. Instead the form is submitted when the user selects an option ( onchange ) using JavaScript. Top: a select box without a button (bad). Bottom: a select box with a button (good). The reason for this is usually to declu.

An easy notation for grayscale colors

These days, there is a lengthy discussion in the CSS WG about how to name a function that produces shades of gray (from white to black) with varying degrees of transparency, and we need your feedback about which name is easier to use. The current proposals are: 1. gray(lightness [, alpha]) In this proposal gray(0%) is.

Confessions Of A CSS Expert

"I guess it all started pretty innocently enough. The UX guys would be asking for a new module or something. You know the sort of thing: a search box or paginator. Whatever. So I'd give that block a class like 'search-widget' or 'paginator'; something to make my stylesheet more readable and to help me contain styles w.

Forms with multiple submit buttons are problematic

Multiple submit buttons are problematic for keyboard users because forms can be submitted by pressing Enter when a field is focused. When this happens the form will be submitted as if the user pressed the first button within the element which isn’t always desirable. An example Take the following address form with a po.

Introducing Whathecolor: A color game for web developers!

I’ve been interested in digital color for a long time, and this year I decided to risk giving a technical talk about color some of the conferences I’m speaking at. “Why is that risky?” you might ask. Well, it might end up being really interesting, or it may end up alienating both designers because it’s too technical a.

Smooth state animations with animation-play-state

When a CSS animation is applied from the beginning of the page load, things are easy. You just use the animation property with appropriate parameters, and you’re done. However, what if the animation is applied on a certain state, e.g. :hover, :active, :focus or a JS-triggered class change? A naïve approach would be to.

Accessible Buttons Jquery Plugin

Please note: The following should be considered an experiment. There is rarely a good reason not to use a element for button-like controls, especially if it means loading a javascript resource just to polfill the behaviors that already offers.

Font Hacking

What if I told you there was a way to radically alter your web pages without using images, javascript, proprietary CSS3 or any extra markup?

Vintage Tobacco Advertising

Rock and roll has always been a contrary form of music. At once 'the devil's music' and the soundtrack to the American Dream , it has leant itself to as much commercial dogma as rebellious transgression. Rock and roll is both savage and servile. It's sexual awakenings and automobile sales. This moral and ideological d.
