CSS Background Properties.

Background Color
The background-color property specifies the background color of an element.
The background color of a page is defined in the body selector:
Examples
background-color:#b0c4de;
background-color:red

Background Image
The background-image property specifies an image to use as the background of an element.
By default, the image is repeated so it covers the entire element.
The background image for a page can be set like this:
background-image:url('paper.gif')

Background Image - Repeat Horizontally or Vertically
By default, the background-image property repeats an image both horizontally and vertically.
Some images should be repeated only horizontally or vertically, or they will look strange, like this:

background-image:url('gradient2.png');
background-repeat:repeat-x;

Background Image - Set position and no-repeat
Remark When using a background image, use an image that does not disturb the text.
Showing the image only once is specified by the background-repeat property:

background-image:url('img_tree.png');
background-repeat:no-repeat;

Background - Shorthand property
As you can see from the examples above, there are many properties to consider when dealing with backgrounds.
To shorten the code, it is also possible to specify all the properties in one single property. This is called a shorthand property.
The shorthand property for background is simply "background":
background:#ffffff url('img_tree.png') no-repeat top right;
When using the shorthand property the order of the property values are:

* background-color
* background-image
* background-repeat
* background-attachment
* background-position

It does not matter if one of the property values are missing,
as long as the ones that are present are in this order.

background: url("image url") no-repeat bottom right;
