I am trying to get rid of this:
document.body.className = "someclass";
I want to do this in CSS.
body.someclass {
.
.
.
}
unfortunately I am not able to get this working in Firefox, chrome.
Am I doing anything wrong here? Is there any way we could apply a CSS class to body?

CSS can be added to HTML documents in 3 ways: Inline - by using the style attribute inside HTML elements. Internal - by using a <style> element in the <head> section.
Type Selectors correspond with HTML elements. ID Selectors are used by adding # in front of an elements ID. Class Selectors are used by adding a period in front of an elements class.
The <style> element must be included inside the <head> of the document. In general, it is better to put your styles in external stylesheets and apply them using <link> elements.
You are doing two different things there. Your JavaScript is actually assigning the class "someclass" to your body element, while your CSS is styling a body element with the class "someclass", it won't assign the class to it, that is not the task of CSS. You would do it in plain (X)HTML like this:
<body class="someclass">
Part of the problem is that valid XHTML can only have one <body> element per document. A class is generally ascribed to an element that occurs multiple times (or, rather, to a style that you want applied multiple times).
SINCE there's only ever one body, I've never added an ID or a class to it. Just style:
body {
background-color: red;
}
If you have a class you want to reuse, use a comma in your selector:
.coolStyle, body {
font-weight: bold;
color: red;
text-decoration: blink;
}
All of this is potentially meaningless, however, because anything applied to the <body> tag will be inherited by its children unless explicitly styled otherwise.
