Default background color is determined by Web browser
Page designer can override the default by specifying BGCOLOR=#RRGGBB in the <BODY> tag. But, user can
set the browser to ALWAYS override a page's color and background.
Contrast is important
Solid background is better than pattern; dark on light or light on dark are better than using background and
text colors that are closer in hue. Many HTML editors and page creation software make the
assignment of background color easy.
Use browser-safe colors
If using background, be careful of high contrast patterns
Add a background pattern using the background=filename.gif element of the <body> tag. This page
is using the file "grbk2.gif" to provide background color. View document source to see the HTML coding.
