Welcome to the CSS-Discuss Wiki

This Wiki is dedicated to real-world (and ideally, browser-neutral) application of CSS (Cascading Style Sheets).

Topics include: techniques for page-layout and special display-effects, testing and validation, workarounds for limitations and bugs, CSS code-editors, beginner and advanced tutorials, and to a lesser extent pure CSS theory, and pure CSS power-demonstrations. Discourse on (X)HTML, DOM, and other webpage- technology areas is not forbidden, but keeping it associated with CSS is encouraged.
