I recently realized that unprefixed gradients finally propagated to stable Chrome, and after tweeting about it, I decided to do some research on which browsers support unprefixed gradients, and what percentage of users needs them. Currently, unprefixed gradients are supported in: Chrome 26+ Firefox 16+ Opera 12.10+ IE10+ Lets have a look at which prefixes [...]
These days, I’m working on the slides for my next talk, “The humble border-radius”. It will be about how much work is put into CSS features that superficially look as simple as border-radius, as well as what advances are in store for it in CSS Backgrounds & Borders 4 (of which I’m an editor). It [...]
I recently found myself looking at the Tools switch in Espresso: Not because I was going to use it (I rarely do), but because I started wondering what would be the best way to replicate this effect in CSS. I set on to create something that adhered to the following rules: It should be keyboard [...]

The CSS Working Group is recently discussing the very serious problem that vendor prefixes have become. We have reached a point where browsers are seriously considering to implement -webkit- prefixes, just because authors won’t bother using anything else. This is just sad. Daniel Glazman, Christian Heilmann and others wrote about it, making very good points [...]

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: [...]
Edit: This was originally written to be posted in www-style, the mailing list for CSS development. I thought it might be a good idea to post it here as other people might be interested too. It wasn’t. Most people commenting didn’t really get the point of the article and thought I’m suggesting we should simply [...]
I recently saw Paul Irish’s jQuery invert page plugin. It inverts every color on a webpage including images or CSS. This reminded me of the invert color keyword that’s allowed on outlines (and sadly only supported by Opera and IE9+). So I wondered how it could be exploited to achieve the same effect through CSS [...]
About a year ago, prof. Vasilis Vassalos of Athens University of Economics and Business approached me and asked for my help in a new course they were preparing for their Computer Science department, which would introduce 4th year undergrads to various web development aspects. Since I was always complaining about how outdated higher education is when [...]
In this post I’m going to share some tips to increase a site’s usability that are very quick to implement. Not all of them are cross-browser, but they are the icing on the cake anyway, nobody would mind without them.
