Textmate newbie question: how to indent CSS

New in TextMate and can't find an answer in the documentation.

I saved a blank file as CSS and the "active package" appears as CSS at the bottom of the screen.

Then I pasted a bunch of CSS from elsewhere (mini page). However, this is all inserted as one line.

How do I make it look like "correct" CSS using TextMate? Text + Indent is just indenting the entire line in one tab.

thanks!
