Way to add text on certain elements on action? [SOLVED]

Instead of just adjusting the color of text of the link of a news article that someone has already visited, (a:visited) I want it to add "Read:" at the beginning of the link of the news article. Simple way to do this?

To add some text via CSS, you'd use the :before pseudo selector:

Code:

---

a:visited:before { content: "Read: "; }

---

Information on what browsers actually support it:

Thank you so much. I'll keep a color change for visited for the older I.E. versions for a backup. That site is extremely useful as well. Didn't know there were so many different types of selectors that have special functions like that.
