There have been many attempts to create boxes with round corners over the years, some using tables, some using Javascript, others with images. This is the first, and possibly only, that uses only CSS and HTML to do so, and it seems to work rather well. While not as awe-inspiringly flexible as some options, its simplicity and code-length (or lack there of) make it stand out.
