Hanging Punctuation

One of the most powerful uses of CSS is to control the typography in your document.

When you have punctuation that appears at the beginning of a line in a paragraph that is left justified, it makes the text look uneven.

Hanging punctuation puts the punctuation into the left margin so the text lines up.

Here's the very basic CSS:

blockquote, blockquote p {
	text-indent: -0.5em;

The blockquote p above is necessary if you are marking up documents to conform to XHTML strict.
