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 […]

Conical gradients, today!

It’s no secret that I like conical gradients. In as early as 2011, I wrote a draft for conical-gradient() in CSS, that Tab later said helped him when he added them in CSS Image Values Level 4 in 2012. However, almost three years later, no progress has been made in implementing them. Sure, the spec is […]

Awesomplete: 2KB autocomplete with zero dependencies

Sorry for the lack of posts for the past 7 (!) months, I’ve been super busy working on my book, which up to a certain point, I couldn’t even imagine finishing, but I’m finally there! I’ve basically tried to cram all the CSS wisdom I’ve accumulated over the years in it 😛 (which is partly why it […]

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 […]

Meet More than you probably wanted to know about screen DPI

Yesterday (Sunday) I was on a 9.5 hour flight from Canada with no inflight entertainment (well, thanks Air Canada), so I did what every bored human being would do instead of watching movies: I decided to code an app! And out of the infinite set of possible apps somebody can make, I decided to make […]

Preview corner-shape, before implementations!

As an editor of the Backgrounds & Borders Level 4 spec, I am naturally a bit more interested in the cool features it will bring, once implementations start (it’s currently too early for that). One of the coolest features in it is corner-shape. While in Backgrounds & Borders 3, border-radius was only used for rounded […]

Easy color contrast ratios

I was always interested in accessibility, but I never had to comply with any guidelines before. At W3C, accessibility is considered very important, so everything we make needs to pass WCAG 2.0 AA level. Therefore, I found myself calculating color contrast ratios very frequently. It was a very enlightening experience. I used to think that […]

Introducing Prism: An awesome new syntax highlighter

For the past three weeks, on and off, I’ve been working on releasing Dabblet’s syntax highlighter as standalone, since many people had requested it. Zachary Forrest  suggested the name “Prism” and I liked it so much I decided to go with it, even though there is an abandoned Mozilla project with the same name. I ended […]

Exactly how much CSS3 does your browser support?

This project started as an attempt to improve dabblet and to generate data for the book chapter I’m writing for Smashing Book #3. I wanted to create a very simple/basic testsuite for CSS3 stuff so that you could hover on a e.g. CSS3 property and you got a nice browser support popup. While I didn’t achieve […]

Introducing dabblet: An interactive CSS playground

I loved JSFiddle ever since I first used it. Being able to test something almost instantly and without littering my hard drive opened new possibilities for me. I use it daily for experiments, browser bug testcases, code snippet storage, code sharing and many other things. However, there were always a few things that bugged me: […]
