how to set css property of one class from another class


Problem :

I am applying css style to "body" and to a div which id is "overlay" like:

    background:#FEFEFE url(../Images/gradientHeader1.png);


"overLay" div is inside noscript tag which renders in the browser only when javascript is disabled in the browser.My requirement is that I have to set "overflow:hidden" in the body when "overLay" div get rendered.Can I set overflow property of the body from #overLay?or any other way?

Solution :

Yes you can do this without scripting:

    <div id="overLay">whatever</div>
    <style type="text/css">
        body {
            overflow: hidden !important;

(You also need a # in your CSS rule: #overLay { ... })
