In this tip I recommend you check out a new Toolbar for Internet Explorer developed by Steven Faulkner, of the National Information and Library Service (NILS). Support for the toolbar is confined to Internet Explorer on Windows, so I haven’t been able to try it out myself (I use a Mac) – however, Gez Lemon of the website Juicy Studio is giving it glowing reviews – and I trust his judgement.
According to the blurb, ‘It is designed to help the user to interrogate aspects (structure/code/content) of a html document that can have an affect on the accessibility of that html document. ‘
It does all sorts of things I would find useful as a developer of accessible websites (validation, screen resolution changes, CSS on/off, links to online checking tools and so on), so I think you will find it very useful. You can find installation instructions, and a full feature list for the accessibility toolbar on the website.
The Web developer tool for Firefox is also worth checking out: http://www.chrispederick.com/work/firefox/webdeveloper/ – and it is according to Mike Pepper, ‘bloody good’.
