In this chapter, you’ll learn common techniques to make your pages easier to read and use. Tabs fit lots of information in a small space and let visitors click a tab to access content in smaller chunks. Tooltips—pop-up windows with additional information about moused-over links, form fields, and other HTML elements—provide supplemental information. An increasingly popular tactic for controlling page content is a slider—sort of a window on the page where content slides in and out of view. Sliders let you showcase content and are commonly used on home pages.
You’ll also learn a few useful techniques for building your own interface widgets: how to determine the dimensions of the browser window, a page element, and the position of elements on a page.
