Accessibility – specifying the language of your page

I’m going to write a few posts on specific things you can do to improve the accessibility of a webpage.

You can identify the primary natural language of a document by making a simple change to your HTML element:

<HTML lang="en">

That’s it – now your site complies with Checkpoint 4.3 of the W3C Accessibility checklist by identifying the primary language of a document.

This very simple tip improves the accessibility of your page – it’s presently Priority 3, so if only mandatory if you’re aiming at AAA compliance. But it’s good practice, a small change and low risk – why not add it to your master page?
