ARIA (WAI-ARIA if you want to be formal) is a set of attributes that you can add to HTML elements. These attributes communicate role, state and property semantics to assistive technologies via the accessibility APIs implemented in browsers. The W3C HTML specification provides information about which ARIA attributes are allowed to be used on each HTML element in section 3.2.7 WAI-ARIA. Developer (u

It’s nearly two years since I suggested a <picture> element as a strawman proposal as a way to solve the problem of responsive images, so let’s have a look at how we’re doing. In September there was a big meetup at Mozilla’s Paris office organised by Mozilla’s Marvellous Mr Marcos who’s been very active in the Responsive Images Community Group and did the hard work of actually turning the <picture

Since the mists of HTML 2 we’ve been able to semantically indicate added or removed information using the elements <ins> and <del> respectively. While seemingly simple on the surface these elements have hidden depths. I’ll also compare and contrast <del> with <s>, recently out of font style rehab and back in HTML5. Let’s start with <ins> and <del>… Using ins and del These two elements have very si

I have to be honest with you: I feel like a fraud writing about JavaScript for HTML5 Doctor. I would feel like a fraud writing about JavaScript for a click-driven ad-splattered content farm, never mind HTML5 Doctor. The thing is though, I’m writing about the classList API, and it’s super easy. If your JavaScript-fu isn’t great and you’re wary of HTML5 APIs, this one is at the perfect temperature f

Whether you’re searching for content or logging in to your e-mail account or Facebook page, using online forms is one of the most common tasks performed on the Web.

When building web sites and web applications, we often need to provide essential feedback to a user informing them of the progress of their request or task, be it uploading a file, playing a video, or importing data. HTML5 makes life easier for us by defining an element whose sole purpose is just that: the <progress> element. The HTML5 specification describes it best: The progress element represen

This is a follow up to my 2009 article Native Audio in the Browser, which covers the basics of HTML5 audio. It may well be worth reading if you want to get a feel for the <audio> element and associated API. Now, two and a half years later, it’s time to see how things are progressing. With many new advanced audio APIs being actively worked on and plenty of improvements to the existing native audio

Using Modernizr to detect HTML5 features and provide fallbacks Modernizr is a JavaScript library that detects which HTML5 and CSS3 features your visitor’s browser supports. In detecting feature support, it allows developers to test for some of the new technologies and then provide fallbacks for browsers that do not support them. This is called feature detection and is much more efficient than brow

Contrary to what HTML5 Please and the W3C would have you believe, CSS3 is not part of HTML5. “But this is HTML5 Doctor,” I imagine you saying. “Why are you talking about CSS3 here?” Well, I want to talk about a very specific part of CSS3, one that works in perfect tandem with HT

Until recently, we developers couldn’t to do much with the state and history of the browser. We could check the number of items in the history and push users forwards and backwards, but this provides little benefit to the user. With the rise of more dynamic web pages, we need more control. Thankfully, HTML5 gives us that control by extending the JavaScript History API. What’s the point? # It goes

The scoped attribute for the <style> element allows you to include styles mid-document that targets a specific element and its children. Depending upon how you look at this, it’ll either be a godsend or a curse. Once you’ve reached the end of this article, I hope you can form your own opinion. Let’s take a quick look at the spec: The scoped attribute is a boolean attribute. If set, it indicates th
