Definition
HTML attribute that provides alternative text when non-textual elements, typically images, cannot be displayed.
Information
ALT text is commonly omitted from web pages, from the smallest personal pages to the largest web corporate sites. Yet, if properly used, ALT text can be quite useful. Among other things, ALT text can:
* provide further detail for an image or the destination of a hyperlinked image.
* enable and enhance access for people with various disabilities.
* provide much-needed information for people who surf the Web with graphics turned off, and people who surf the Web with text-only browsers.
* assist in navigation when a graphics-intensive site is being viewed over a slow connection, enabling site visitors to make navigation choices before graphics are fully rendered.
