Flexible CSS Teaser Box
This is a box with flexible height and width. It uses two background images (tsr-l.gif and tsr-r.gif) to create the rounded corners and the top and bottom borders. CSS is used for the left and right borders. This box will expand vertically to contain any amount of text, of almost any size. How far it will be able to expand horizontally before it breaks depends on the size of the background images used. This example will break at a width of 1600 pixels. In most cases, that will be overkill, and one of the background images can be narrowed a bit to save a few hundred bytes.
