In this article, I've pieced together 30 excellent CSS techniques and examples that showcases the capabilities and robustness of CSS.
You'll see a variety of techniques such as image galleries, drop shadows, scalable buttons, menus, and more - all using only CSS and HTML.
Tree-like navigation using nested lists, great for sitemap pages.
3 bar graph examples - "Basic CSS Bar Graph", "Complex CSS Bar Graph", and "Vertical CSS Bar Graph" using div's and definition list tags.
The important thing is to not fall victim of doing some things, just because you can, but instead apply these techniques appropriately where they add to the design or functionality of a web design.
