描述
the vlinkcolor property is expressed as a hexadecimal rgb triplet or as one of the string literals listed in color values. this property is the javascript reflection of the vlink attribute of the <body> tag. the default value of this property is set by the user on the colors tab of the preferences dialog box, which is displayed by choosing general preferences from the options menu. you cannot set this property after the htm source has been through layout.
if you express the color as a hexadecimal rgb triplet, you must use the format rrggbb. for example, the hexadecimal rgb values for salmon are red=fa, green=80, and blue=72, so the rgb triplet for salmon is "fa8072".
例子
