Earlier this week, we published a number of new tests for web standards on our IE Test Center page, together with a harness to run them automatically in your browser as well as cross-browser pass rate statistics for these new tests. We quickly received web community feedback that the pass rate data in the first table was prone to misinterpretation. What the Test Center Pass Rates Include: T...
We’re always excited to engage with members of the W3C including the developers of other browsers as well as the broader web development community to help shape the direction of emerging Web standards, particularly HTML5. This includes participating in events like TPAC, which we wrote about in November, and on-going engagement with various working groups. Patrick recently talked abou...
The first time we used ‘The CSS Corner’ as a general blog post heading, Chris Wilson sent this feedback: “Many readers will think the post is about border-radius”. The very first comment proved him right within hours. Today, CSS Corner is about the border-radius property, by far the most heavily requested feature of the CSS3 Backgrounds & Borders module. A factor behind this popul...
Tab isolation has recently become a more popular topic. This post is a quick survey of what tab isolation is, how it works, and what it provides. What is it? Tab isolation is a way to improve a browser’s reliability by containing the impact of a crash. Depending on how it’s implemented, tab isolation can also help contain some security attacks. There are two different implementations a...
As part of our commitment to standards and interoperability, we are excited to provide initial support for the W3C’s Scalable Vector Graphics (SVG) 1.1 (Second Edition) Specification in the Internet Explorer 9 Platform Preview. The second edition of the SVG spec contains updates to the W3C-Recommended first edition SVG 1.1 specification. We expect SVG, supported by good user and developer experi...
There are many tools in the market that allow you to customize your pages' cascading style sheets (CSS), but there are actually a very few that do the opposite—scan for all the CSS rules in the document and remove those that are not used. Cleaning out the CSS will not only reduce the bandwidth impact, but will also improve the performance of the browser (minimizing the time spent by the CSS engi...
Getting specific feedback directly from developers about their experiences with the platform is super important to us. It’s a critical part of how we optimize for real world performance and real world code patterns. This post is about the changes we’re making to our feedback programs in support of broadening and strengthening that feedback loop. Feedback about Feedback Your feedback about ho...
Last week, the W3C HTML Working Group reached a decision to publish several new working drafts and these are now available. The discussion about what to publish and how to structure the HTML5 specification has taken several months. In November, at the TPAC meeting, a request was made for the Microdata section of the specification to be removed. Back in August, I posted about our support for a sepa...
When we started looking deeply at HTML5, we saw that it will enable a new class of applications. These applications will stress the browser runtime and underlying hardware in ways today’s websites don’t. We quickly realized that doing HTML5 right – our intent from the start – is more about designing our browser’s subsystems around what these new applications will need than it is about a ...
The Windows Internet Explorer Platform Preview build marks an important milestone in the development of the next version of Internet Explorer. A significant part of the platform preview is focused on new or proposed World Wide Web Consortium (W3C) web standards. The goal of industry standards is actually “interoperability.” For HD television standards, that means that mult...
