A surprising number of Web sites have color specified for body text, headings, and links of all kinds yet not for the background. Because your visitor may have any color set in their preferences, they may:
The rule of thumb to avoid these problems is: If you specify one color, you must specify them all.
The proper, modern way to set color in a Web page is to use Cascading Style Sheets. This is strongly recommended over the use of <body> attributes and the <font> element in HTML, because CSS is more flexible, easier to maintain and saves bandwidth. Use the CSS properties <color> and <background-color> or its shorthand <background>.
The background, foreground and link colors are all specified in this simple black on white page.
html, body { background: #fff; color: #000; } a:link { background: #fff; color: #037; } a:visited { background: #fff; color: #636; }
Some of the advice here differs from ours.
