Wicked! Does this work in all browsers?

Hello. I'm curious, is there a "content" property in CSS?I was reading through an email digest I subscribe to and someone posted a CSS snippet with a content property. It looked like this:

code:before { content: " <?"; display:block; } code:after { content: " ?>"; display: block; }

Is this for real or am I dreaming? What does this do, exactly?Thanks.
