hiding text using "text-indent"

Question

I'm trying to hide some text inside an <li> element using CSS by setting text-indent: -999px;.
For some reason this doesn't work when I set the direction of the document to "rtl" (right to left - my site is in Hebrew).
When direction is "rtl" the text still shows...
Anyone knows why, and a way around this?

Answer 1

Have you tried a positive text-indent?

Answer 2

The text-indent: -99px is an old trick, which is not the optimal way to hide text. Why not use visibility:hidden instead?
