CSS Background, Image and Color Styles

One of the interesting things about using CSS is that most things can have a background image, background color, and foreground color. The entire page's properties can be made using a body selector, while you can easily use other selectors such as p or table to define background and color properties.

You are probably familiar with the <body> tag. A typical <body> tag looks something like this:

<body background="graphic.jpg" text="#FFFFFF" bgcolor="#000000">

To convert that into CSS, it looks like this:

body { background-image: url(graphic.jpg);
color: #FFFFFF; background-color: #000000; }

Big deal right? But CSS adds some special features. One of the most important is the background-repeat property. It has these values: repeat, repeat-x, repeat-y, or no-repeat. A regular web page has a default of background-repeat: repeat, which means the image is repeated both horizontally and vertically. With CSS, you can set the background to repeat horizontally (repeat-x), repeat vertically (repeat-y), or not repeat at all (no-repeat).

We can edit the style mentioned above to have the body's background never repeat by adding background-repeat: no-repeat:

body { background-image: url(graphic.jpg);
color: #FFFFFF; background-color: #000000;
background-repeat: no-repeat; }

If you want to include the repeat in your standard background tag (for example, if are not using CSS for the rest of your page), you can add style="background-repeat: no-repeat;", so it looks like this:

<body background="graphic.jpg" text="#FFFFFF" bgcolor="#000000" style="background-repeat: no-repeat;">

Remember that although over 90% of web browsers in use today support CSS, there are still some that do not. It may be helpful to use the standard <body> tag to define a text and bgcolor, and then use a style sheet to define everything else, using the same color and background-color values.

If you are using anything but repeat for a background-repeat, you should read the margin chapter of this guide to make sure your background doesn't make your text hard to read.
