The meaning of ">" in style

[dotJoon]

html >body #outer{height:auto;}

What does ">" mean here?

[maxor]

Paul is using a child selector.

That says that all body elements, which are children (contained in) html elements have an id named outer with an auto height.

/* All paragraphs in a body element are red */

body > p { color: #F00; }
