IE8: CSS Expressions are no longer supported in Standards Mode

In case you don’t know, CSS expressions were actual bits of JavaScript that you could run from CSS rules; this was commonly used to simulate the CSS max-width property for IE:

 
CSS:
  1.  
  2. div.someClass {
  3. /* Internet Explorer */
  4. width: expression(document.body.clientWidth> 600) ? "600px" : "auto";
  5. /* Standards-compliant browsers */
  6. max-width: 600px;
  7. }

  1. The good news about this is that IE8 now supports max-width etc so you shouldn’t need to use it for that.

    But on the other hand – it was a handy work-around for IE rendering problems :(

  2. Stewart: the only problematic Microsoft browser Re CSS 2.1 max-width property is IE6 used by approximately 25% of people currently online. For IE7 and 8 it works perfectly fine.

    See the CSS 2.1 minimum and maximum height and width test case results for IE. 3 versions tested, IE6-8.

  3. Sorry. max- and min-width don't work for me at all with IE8, compatibility mode or not. No matter what doctype (html and xhtml tested). Neither do CSS expressions.

  4. Actually, IE8 max-width is not properly working on 1360x700px resolution.
