The color Property

The color property of a style attribute specifies the text color of an HTML

element. The particular color itself can be specified in several ways:

  Using one of the sixteen standard HTML colors: aqua, black, blue, fuchsia,

gray, green, lime, maroon, navy, olive, purple, red, silver, teal, white, and

yellow.

  As a hexadecimal number in the form #rrggbb where r,g,b are hexadec 

imal digits: 0,1,2,3,4,5,6,7,8,9,a,b,c,d,e,f.

  As a 3 digit hexadecimal number #rgb

  As a term of the form rgb(R,G,B), where R,G,B are numbers between 0

and 255

  As a term of the form rgb(R%,G%,B%), where R,G,B are decimal numbers

between 0.0 and 1.0.

In each case but the first, the color is specified as a combination of red, green,

and blue light, and the R,G,B parameters specify how much of each of the

primary colors to use in the desired color.

url(page.gif)

or url(http://x.com/page.gif) or

For example, the following body tag specifies that the sincos.gif  image should

be used as the background for the page:
