In this blog post, I’m continuing the work I started on the first leaked build of Windows 8.1 to include the new changes introduced in the latest leaked build of IE11 (namely build 9385 leaked a few days ago).

On the eve of HTML Web Components, and of stronger than ever Responsive Design requirements, the need for Element Media Queries is becoming very visible. This blog post will try to make a case for a JavaScript prollyfill and gives some background on why the :min-width pseudo-class is so difficult to implement.

Here are some of the new features (CSS/JavaScript) I noticed when working in the leaded IE11 build (please note that the build seems quite old to me, probably very near of the RTM version of IE10).

The Extensible Web Community Group is currently working on his first project: a polyfill code generator. The goal of the project is to generate a stub JavaScript code from some WebIDL definition. To ensure maximum compatibility, we need to follow the WebIDL type conversion rules: but how do we do this efficiently?

Back in early 2010, I made a lightening talk on how I thought a new kind of innovation process started to drive the web forward. Today, I think this model is becoming more and more the predominant model of evolution of web standards.

A few days ago, Microsoft introduced TypeScript. Many IT news websites defined TypeScript as a “Super Javascript” from Microsoft, but what is it really? Why was he crafted? What are Microsoft plans going forward?

I’m proposing to add ‘rpx’ aka the ‘Responsive Pixel Unit’ to later revisions of CSS Values and Units. It’s value is computed as follow: (1rem) / (the default font size settings of the browser).

These days, most JavaScript libraries perform data binding. Data binding means updating the UI automatically as a result of a model change using the Observer-Observee principle. Here’s my take on the data binding standardization.

These days, many people advocate for the use “image sets”. Meanwhile, image sets is just a way to put more burden on the developer by asking him to specify two image urls in his markup if he want to support high-resolution screens (phones, tablets, and high-end notebooks).

Some time ago, there has been a big PR ongoing by the people of the Web Performance WG to make sure we used requestAnimationFrame in our websites instead of setTimeout when it was available.

However, the latest drafts (which were implemented in IE10) introduced an undetectable breaking change from the currently published working draft, which can break your existing websites using the requestAnimationFrame function.

There’s no way to make designs responsive to ambient light variations in CSS today. This is strange, and I think it should change…

We can divide the mails we receive in our mail box into multiple categories. Some are personal messages. Some, however, are automatically generated notifications. It’s therefore amazing no one (Apple, Microsoft, Google) actually integrated mails to their notification systems.

A while back I tweeted that users and authors, to the contrary of the popular belief, are less important than browser implementers and spec writers in standards committees. I really think it is the case, and I’ll care to explain why in this blog post.

While everybody seems to be using WordPress right now, there’s no reason not consider making your own blogging platform. In this blog post, I’m sharing my experience on the creation of a blogging platform.

Many subjects are being discussed in the CSS Working Group. So many subjects, in fact, that you can't get involved in all of them. However, some are more critical to the future of the CSS language than others. And I truly believe that the current css-variables discussion is one of them.
