CSS Background
CSS background properties are used to define the background effects of an element.
CSS properties used for background effects: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:
With CSS, a color is most often specified by:
- a HEX value - like "#ff0000"
- an RGB value - like "rgb(255,0,0)"
- a color name - like "red"
In the example below, the h1, p, and div elements have different background colors:
Example
h1 {
background-color: #6495ed;
}
p {
background-color: #e0ffff;
}
div {
background-color: #b0c4de;
}
background-color: #6495ed;
}
p {
background-color: #e0ffff;
}
div {
background-color: #b0c4de;
}

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:
Below is an example of a bad combination of text and background image. The text is almost not readable:
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:
If the image is repeated only horizontally (repeat-x), the background will look better:
Example
body
{
background-image: url("gradient.png");
background-repeat: repeat-x;
}
background-image: url("gradient.png");
background-repeat: repeat-x;
}

Note: When using a background image, use an image that does not disturb the text. |

Example
body
{
background-image: url("img_tree.png");
background-repeat: no-repeat;
}
background-image: url("img_tree.png");
background-repeat: no-repeat;
}

The position of the image is specified by the background-position property:
Example
body
{
background-image: url("img_tree.png");
background-repeat: no-repeat;
background-position: right top;
}
background-image: url("img_tree.png");
background-repeat: no-repeat;
background-position: right top;
}

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":
When using the shorthand property the order of the property values is:
- background-color
- background-image
- background-repeat
- background-attachment
- background-position
