How can I replace text with CSS?

Question

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

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

Instead of ( img

Obligatory: This is a hack: CSS isn't the right place to do this, but in some situations - eg, you have a third party library in an iframe that can only be customized by CSS - this kind of hack is the only option.

You can replace text through CSS. Let's replace a green button that has the word 'hello' with a red button that has the word 'goodbye', using CSS.

Before:

After:

See http://jsfiddle.net/ZBj2m/274/ for a live demo:

Here's our green button:

Hello

button {
  background-color: green;
  color: black;
  padding: 5px;
}

Now let's hide the original element, but add another block element afterwards:

button {
  visibility: hidden;
}
button:after {
  content:'goodbye'; 
  visibility: visible;
  display: block;
  position: absolute;
  background-color: red;
  padding: 5px;
  top: 2px;
}

Note:

• We explicitly need to mark this as a block element, 'after' elements are inline by default
• We need to compensate for the original element by adjusting the pseudo-element's position.
• We must hide the original element and display the pseudo element using visibility. Note display: none on the original element doesn't work.
