Abstract:

Very few designers appreciate the aesthetic of a text input field, and styling form fields cross-browser on any Web site can be a tedious and frustrating experience. The compromise typically involves applying a simple colored border and background to the fields. I think this is the right approach for Web sites and applications that are form field intensive, but the search box plays a special role in the design, and it deserves a little more attention.
