> selector

Explorer 4 and 5.0 on Windows select all paragraphs.

Not at all supported by Explorer 5.5 and 6 on Windows.

Selects an element that is the child of another element.

Testsheet:

body > p {font-style: italic;}

The > selector means "child of", so that this style sheet should make the text in all P's that are direct children of BODY italic. It should not make the P's in the browser compatibility DIV at the top of the page italic, though. These P's are not direct children of the BODY element and should remain unaffected.
