How can I replace text with CSS?

How can I replace text with CSS using a method like this:

.pvw-title img[src*="IKON.img"] { visibility:hidden; }

Instead of ( img[src*="IKON.img"] ), I need to use something that can replace text instead.

I have to use [ ] to get it to work.

<div class="pvw-title">Facts</div>

I need to replace “Facts“.
