clipped from: www.smileycat.com This collection of techniques to create boxes with rounded corners using CSS has become quite popular. The problem now is there are so many choices it's hard to know which one to choose.
To that end I've provided some more information about each method in order to help people choose which best fits their needs.
Some of these techniques use CSS and one or more background images, some use CSS, JavaScript and no images, and a couple use only CSS — no images or JavaScript required (more markup is needed though).
There are so many different techniques now, it really depends on your individual requirements and preferences; particularly whether you want to use a JavaScript-based technique or not.
Try out a few methods and see if there's one that fits.
