Reading CSS value using JavaScript

Question

This works:

Answer 1

In InternetExplorer you can use .currentStyle instead of .style. In other browsers, you can use the getComputedStyle mechanism.

var yourElement = document.getElementById('whatever');
var theStyle = window.getComputedStyle(yourElement);

You can then call .getPropertyValue() on the returned style object to find the CSS properties you're interested in.
