Question

What I want to do is something like:

#div_id > .some_class 
{
}

I don’t want to change the class everywhere. I only want to change the class if it in that particular div.

Is ther some other way to do that same thing?

Answer 1

You’ve already stumbled upon the answer yourself:

#div_id > .class {
    /* CSS magic */
}

This selects .class if it is the direct descendant of #div_id. For all descendants regardless of depth, use the selector #div_id .class instead.
