This is an attractive "blue shading" image Tab Menu. The shade effect is created using two gradient background images, one for the overall tabs, and the other, for the currently "active" tab. Based partially on the Basic Tabs menu, Shade Image Tabs Menu supports three commonly requested features:
Ability to align the menu tabs "left", "center", or "right" on the page
Highlight a particular tab so it appears selected/ active,
Change the width of the TAB menu (so the underline beneath it spans a length other than the entire width of the page.
