Wire Frame Aura Menu
Author: Dynamic Drive
This is a clean looking CSS menu with simply a gray border outlining its edges. To add a little flare, an "aura" effect is added when the mouse moves over the menu items, realized using a gradient ellipse image. This menu supports easy alignment other than "left", such as "center" or "right" instead.
Single image used (3 flavors to choose from):
