CSS image replacement

CSS image replacement is a dated web design technique that uses Cascading Style Sheets – as opposed to other technologies, like Flash – to replace text on a web page with an image containing that text. It is intended to keep pages accessible to users of screen readers, text-only web browsers, or other browsers where support for images or style sheets was either disabled or nonexistent, while allowing the image to differ between styles. One of many techniques was the Fahrner image replacement, named after Todd Fahrner, who was credited with the idea of image replacement in 2003.

With the introduction of CSS web font support in all major web browsers, CSS image replacement is now little used.
