CSS TUTORIALS

Backgrounds:

What is CSS Background
CSS background properties are used to define the background effects of an element.
CSS properties used for background effects:
  • background-color
  • background-image
  • background-repeat
  • background-attachment
  • background-position
How to set 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:
Example
body {
background-color: #b0c4de;
}

With CSS, a color is most often specified by:
a HEX value - like "#cc0000"
an RGB value - like "rgb(150,0,0)"
a color name - like "blue"

-color: #000000;
}
How to set 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:
Example
body {
background-image: url("landscape.gif");
}

How to set 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:
Example
body {
background-image: url("coolbackground.png");
}

If the image is repeated only horizontally (repeat-x), the background will look better:
Example
body {
background-image: url("coolbackground.png");
background-repeat: repeat-x;
}

How to - Set position and no-repeat in Background Image

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":
Example
body {
background: #ffffff url("img_flower.png") no-repeat right top;
}
When using the shorthand property the order of the property values is:

  • background-color
  • background-image
  • background-repeat
  • background-attachment
  • background-position
It does not matter if one of the property values is missing, as long as the ones that are present are in this order.
