The easiest way to make the content of your site accessible to a wider audience, including people with text-only browsers. Helpful to users who have their graphics turned off for faster page downloading. ALT tags provide assistance to screen readers

Additional colors lessen the effectiveness of the color scheme

22 Using JavaScript for Good

23 JavaScript in Action A simple example of Javascript in action is the image rollover, where one image is swapped for another when the mouse rolls over it. A more sophisticated example is a JavaScript powered shopping cart. Make sure the use of JavaScript does not slow down the loading of the Web page.
