CSS allows you to apply a solid color as a background, and also allows you to create quite complex effects using a background image.

Solid Color background background image

body{

Background: #ff0000 URL (/i/eg_bg_03.gif) no-repeat Fixed Center;

}

1, solid color background: Background-color

Body   {  background-color:yellow;  } H1   {  background-color:#00ff00;  } P   {  background-color:rgb (255,0,255);  }
Range of element backgrounds

The Background-color property sets a solid color for the element. This color fills the element's content, padding, and border areas, extending to the outer bounds of the element's border (but excluding margins). If the border has a transparent part (such as a dashed border), the background color is displayed through these transparent sections
