When you add a single, not-repeating background image to your Web page, it appears, by default, in the top left corner of the viewpoint. You can set the image to be displayed anywhere else on the page, by using CSS property background-position. The next CSS test file centers the image on the page:

File test.css

body {

background-color: #ffffff;

background-image: url(psy.jpg);

background-repeat: no-repeat;

background-position: center center;

}

h1 {

text-align: center;

font: 24px Arial, Helvetica,Geneva ,Verdana, sans-serif;

}

p {

text-align: center;

font: 14px Arial, Helvetica,Geneva ,Verdana, sans-serif;

line-height: 1;

}

 

You can use for example the next test file:

 

File test.html

<!DOCTYPE html PUBLIC “-//W3C//DTD XHTML 1.0 Strict//EN”

“https://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd”>
