Web Page Animation

by Joe Gillespie — Jul 1, 1998

Choosing an animation technique to use on a Web page is primarily a trade-off between quality and file size. It also depends very much on how much effort the designer is prepared to put into producing it in the first place.

Ok, we are not talking about Disney epics here, we are looking at ways to attract the eye in a basically static medium. The simplest animation technique is the animated GIF used mostly for banner ads.

The GIF file format is best used for flat graphics as its LZW compresses these most efficiently. Colour depths can be reduced from the 8-bit maximum to one just sufficient to display the colors necessary. This helps to reduce file size - and bandwidth.
