Persistent sessions are possible. The way I'm doing it in the CMS I am working on is via GET which saves selection in session. I can't use a selector because I tailor the web page to the style sheet and some of them require different page design (IE search bar in aside opposed to header) I don't use persistent sessions, but session is kept in cookie and you can configure it to be a persistent cookie if you want.

Dealing with style sheet caching by all the different browsers and the user's settings for them is the big problem. I'd suggest this: Use the sessions buffer for simplicity. And, link your complete [all the selectors] default css file in the header. Then, include ONLY the selectors needed to render the special selectors in the html's header style block. These selectors will override those in the css file. Now, simply modify the selectors here when you return the page. Far as I know, all browsers honor revised styles when they are in the page html header. <header> <style type="text/css"> <!-- special selectors go here --> </style> </header>

Just make your site zoom-cooperative, such as: http://sperling.com/examples/zoom/ As far as making things high contrast, why not choose colors that are right the first time? Try this: http://webbytedd.com/c/access-color/ As far as making all of this persistent, look to using Cookies.

For example, some people with learning difficulties benefit from yellow text on blue backgrounds, as apparently those colours together are better at capturing a users attention for longer durations. This is often coupled with other layout changes such as narrower width text blocks to aid readability. Thanks, Ash http://www.ashleysheridan.co.uk |
