W3Conf in San Francisco, February 21-22

You might have heard about W3Conf, W3C’s conference for web designers and developers. This year, I have the pleasure of not only speaking there but also organizing it, along with Doug Schepers and designing the website for it. Alongside with yours truly, it features an excellent lineup of amazing speakers like Eric Meyer, Alexis Deveria of […]

One year of pastries

Last September, I was approached by Alex Duloz, who invited me to take part in his ambitious new venture, The Pastry Box Project. Its goal was to gather 30 people (“bakers”) every year who are influential in their field and ask them to share twelve thoughts — one per month. For 2012, that field would […]

CSS Animations with only one keyframe

This is a very quick tip, about a pet peeve of mine in almost every CSS animation I see. As you may know, I’m a sucker for reducing the amount of code (as long as it remains human readable of course). I demonstrated a very similar example in my “CSS in the 4th dimension” talk, […]

Lots of improvements coming to dabblet

I posted about this in both the WebPlatform.org blog and Dabblet’s blog, but I thought it might be interesting to many readers of this blog as well: As many of you probably know, I’ve started working for W3C Developer Relations since this August. Half of my time is devoted to WebPlatform.org, a very promising project […]

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 […]

Dive deep into CSS3 (and Bolognese!) in Bologna, Italy

I don’t usually like to advertise my talks or workshops through blog posts, and even though I’ve given a lot, I’ve only posted about less a handful. However, this one is special: It might be my last. Don’t get me wrong: I LOVE giving workshops, teaching people new things and seeing them put them in […]

lea@w3․org

In my recent post describing how I got into web development I wrote that I’m in the verge of some big changes in my life. The main one of them starts tomorrow. As of tomorrow, the above will be my professional email. Yes, you guessed it right; I’m joining the W3C team! Yes, the same W3C you all know and […]

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 […]

Important -prefix-free update

Those of you that have been following and/or using my work, are surely familiar with -prefix-free. Its promise was to let you write DRY code, without all the messy prefixes, that would be standards-compliant in the future (which is why I’m always against adding proprietary features in it, regardless of their popularity). The way -prefix-free […]

So, you’ve been invited to speak

I’ve been lucky enough to be invited to do about 25 talks over the course of the past few years and I have quite a few upcoming gigs as well, most of them at international conferences around Europe and the US. Despite my speaking experience, I’m still very reluctant to call myself a “professional speaker” or […]
