> Hello, > I'm wondering whether/how its possible to re-write CSS styles via Javascript? I read the SwitchyMcLayout article on ALA, and it got me thinking - could I change the z-index of a div based on the window size of the browser? Without an example page that is a bit tricky to do. Generally you can change the z-index of an element with the style property. Say if your element has the ID "main" it'll be: var obj = document.getElementById('main'); obj.style.zIndex = 100; You can read the window size of the browser with window.innerWidth. These examples should get you on the way: http://beginningjavascript.com/Chapter5/index.html Easiest would be a demo URL though. -- Chris Heilmann Book: http://www.beginningjavascript.com Blog: http://www.wait-till-i.com Writing: http://icant.co.uk/
