Question

I have a CSS file, which contain the style information of my web.
Some height & width is based on the screen size, so I can calculate the size using
the Javascript, can I embedded the javascript in the CSS file to do so?

Answer 1

In IE, and only IE, you can use CSS expressions:

width: expression(blah + "px");

Then width becomes whatever’s inside the brackets.

This only works in IE, though – so don’t use it. Use a JS function to assign the elements the style with element.style.width or similar.

For example:

<script type="text/javascript">
    document.getElementById('header').style.width = (100 * 2) + 'px';
</script>
