I want to understand how web accessibility experts deals with websites if they want to confirm that those sites are compatible with accessibility guidelines. Do they have to understand any server-side language? or just HTML and CSS?

For example, if there is a company website which provides services for other sites to ensure the accessibility for them, do they have to have a look at the server side code or only the output HTML and CSS?

  • By "services for other sites to ensure the accessibility for them" do you mean providing a report on accessibility and problems that need to be addressed? Or a service that includes actually addressing any problems? Commented Jan 14, 2013 at 5:03
  • Addressing any problems..

Usually just the output. The only server-side issue I can think of now is how to ensure a site has pretty urls like, "/user/logins/all-time" instead of /index.php?item=users&lookup=logins&timeframe=all-time, which is not at the height of accessibility. (usually mod_rewrite magic in an .htaccess file, but so many other ways, too).

But, by far, the most important aspect of accessibility, IMHO, is the content; HTML markup is merely a sub-topic of that.
