reset multiple css styles for one single div element

Question

my question is if it is possible to reset css styles (a lot off them) for a single div and all elements that are contained in that div.

I am asking, because I found

Answer 1

Try this:

div.foo, div.foo *
{
    // your styles
}

which will apply the styles to the div with class "foo" and all its descendants. The star (*) is known as the universal selector, and not surprisingly, selects elements of any type.

Or for just the immediate children:

div.foo, div.foo > *
{
    // your styles
}
