This shadowed border has a width of 80% and hence scales with the size of your browser window. Try it out ;-) And now some Lorem ipsum:

- <a href="#">Tab 1</a>
- <a href="#">Tab 2</a>
- <a href="#">And a third tab</a>
Tabs that change the color when hovered over (hover works on all supported browser but Internet Explorer 6.0).
Links that "glow" when hovered over - this is alpha code... It doesn"t work in IE6 and Opera and looks strange in Safari. This is some text with some <a href="#" class="sbi">links</a>. Don"t get bored by the content but hover over the links ... This is some text with some <a href="#" class="sbi">links</a>. Don"t get bored by the content but hover over the links ...
