Adding a Page Background
You're now ready to create a background for the Cycle Pathology home page. Dan has a
graphic image of a cyclist standing before a sunset. He wants you to place this image in
the top-left corner of the page body against a black background. He does not want you
to tile the image.
You'll place a style rule for the page background in a new style sheet fi le that you'll
create now.
To format the page background:
1. Open the cp_stylestxt.css file in your text editor. Type your name and the date in
the comment section at the top of the file, and then save the file as cp_styles.css .
2. Below the comment section, insert the following style rule (see Figure 4-10):
/* Styles for the Page Body */
body {
background: black url(bike_bg.png) top left no-repeat;
