Computer says NO to HTML5 document outline

by Steve Faulkner.

What a brilliant idea! For the longest time HTML5 specified, and advised developers, that it no longer mattered what the number (1 to 6) was in a heading element (when used in conjunction with sectioning elements). What mattered was the nesting level of the H1-h6 in sectioning elements, just like the X<H>TML promised land, but […]

The woes of date input

by Ian Devlin

One of the many new input types that HTML5 introduced is the date input type which, in theory, should allow a developer to provide the user with a simple, usable, recognisable method of entering a date on a web page. But sadly, this input type has yet to reach its full potential. Briefly, the date […]

HTML Developers: Please Consider

by Steve Faulkner

ARIA is an amazing technology, it allows developers to add meaning to meaningless HTML or override meaning on HTML that is being repurposed and sometimes misused, so that users who rely upon the meaning of HTML, as implemented in browsers, can understand and interact with HTML User Interfaces successfully.

Using ARIA in HTML

by Steve Faulkner

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 […]
