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

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

<html>
<head>
<style type="text/css">
body
{
background-color:#b0c4de;
}
</style>
</head>

<body>

<h1>My CSS web page!</h1>
<p>Hello world! This is a W3Schools.com example.</p>

</body>
</html>

Try it yourself in Notepad or Dreamweaver by coping and pasting the code above.
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"
Look at CSS Color Values for a complete list of possible color values.
In the example below, the h1, p, and div elements have different background colors:

Example

<html>
<head>
<style type="text/css">
h1
{
background-color:#6495ed;
}
p
{
background-color:#e0ffff;
}
div
{
background-color:#b0c4de;
}
</style>
</head>

<body>

<h1>CSS background-color example!</h1>
<div>
This is a text inside a div element.
<p>This paragraph has its own background color.</p>
We are still in the div element.
</div>

</body>
</html>

Try it yourself in Notepad or Dreamweaver by coping and pasting the code above.
Result:

CSS background-color example!

This is a text inside a div element.
This paragraph has its own background color.
We are still in the div element.


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

<html>
<head>
<style type="text/css">
body {background-image:url('your_image.gif');}
</style>
</head>

<body>
<h1>Hello World!</h1>
</body>

</html>

Try it yourself in Notepad or Dreamweaver by coping and pasting the code above.

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 shaded image: 

Example

<html>
<head>
<style type="text/css">
body
{
background-image:url('your_image.png');
}
</style>
</head>

<body>
<h1>Hello World!</h1>
</body>

</html>

Try it yourself in Notepad or Dreamweaver by coping and pasting the code above.
If the image is repeated only horizontally (repeat-x), the background will look better for shaded image:

Example

<html>
<head>
<style type="text/css">
body
{
background-image:url('your_image.png');
background-repeat:repeat-x;
}
</style>
</head>

<body>
<h1>Hello World!</h1>
</body>

</html>

Try it yourself in Notepad or Dreamweaver by coping and pasting the code above.

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:

Example

<html>
<head>
<style type="text/css">
body
{
background-image:url('your_image.png');
background-repeat:no-repeat;
}
</style>
</head>

<body>
<h1>Hello World!</h1>
<p>W3Schools background image example.</p>
<p>The background image is only showing once, but it is disturbing the reader!</p>
</body>

</html>

Try it yourself in Notepad or Dreamweaver by coping and pasting the code above.
In the example above, the background image is shown in the same place as the text. We want to change the position of the image, so that it does not disturb the text too much.
The position of the image is specified by the background-position property:

Example

<html>
<head>

<style type="text/css">
body
{
background-image:url('img_tree.png');
background-repeat:no-repeat;
background-position:right top;
margin-right:200px;
}
</style>

</head>

<body>
<h1>Hello World!</h1>
<p>W3Schools background no-repeat, set postion example.</p>
<p>Now the background image is only shown once, and positioned away from the text.</p>
<p>In this example we have also added a margin on the right side, so the background image will never disturb the text.</p>
</body>

</html>

Try it yourself in Notepad or Dreamweaver by coping and pasting the code above.


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":

Example

<html>
<head>

<style type="text/css">
body
{
background:#ffffff url('your_image.png') no-repeat right top;
margin-right:200px;
}
</style>

</head>

<body>
<h1>Hello World!</h1>
<p>Now the background image is only shown once, and it is also positioned away from the text.</p>
<p>In this example we have also added a margin on the right side, so that the background image will not disturb the text.</p>
</body>

</html>

Try it yourself in Notepad or Dreamweaver by coping and pasting the code above.
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 is missing, as long as the ones that are present are in this order.
This example uses more advanced CSS. Take a look:
Example

<html>
<head>
<style type="text/css">
body
{
margin-left:200px;
background:#5d9ab2 url('img_tree.png') no-repeat top left;
}


.container
{
text-align:center;
}


.center_div
{
border:1px solid gray;
margin-left:auto;
margin-right:auto;
width:90%;
background-color:#d0f0f6;
text-align:left;
padding:8px;
}
</style>
</head>


<body>
<div class="container">
<div class="center_div">
<h1>Hello World!</h1>
<p>This example contains some advanced CSS methods you may not have learned yet. But, we will explain these methods in a later chapter in the tutorial.</p>
</div>
</div>
</body>
</html>

TEXT FORMATTING

This text is styled with some of the text formatting properties. The heading uses the text-align, text-transform, and color properties. The paragraph is indented, aligned, and the space between characters is specified.

Text Color

The color property is used to set the color of the text.
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"
Look at CSS Color Values for a complete list of possible color values.
The default color for a page is defined in the body selector.

Example

<html>
<head>
<style type="text/css">
body {color:red;}
h1 {color:#00ff00;}
p.ex {color:rgb(0,0,255);}
</style>
</head>

<body>
<h1>This is heading 1</h1>
<p>This is an ordinary paragraph. Notice that this text is red. The default text-color for a page is defined in the body selector.</p>
<p class="ex">This is a paragraph with class="ex". This text is blue.</p>
</body>
</html>

Try it yourself in Notepad or Dreamweaver by coping and pasting the code above.
Result:

This is heading 1

This is an ordinary paragraph. Notice that this text is red. The default text-color for a page is defined in the body selector.
This is a paragraph with class="ex". This text is blue.


Remark For compliant CSS: If you define the color property, you must also define the background-color property.

Text Alignment

The text-align property is used to set the horizontal alignment of a text.
Text can be centered, or aligned to the left or right, or justified.
When text-align is set to "justify", each line is stretched so that every line has equal width, and the left and right margins are straight (like in magazines and newspapers).

Example

<html>
<head>
<style type="text/css">
h1 {text-align:center;}
p.date {text-align:right;}
p.main {text-align:justify;}
</style>
</head>

<body>
<h1>CSS text-align Example</h1>
<p class="date">May, 2009</p>
<p class="main">In my younger and more vulnerable years my father gave me some advice that I've been turning over in my mind ever since. 'Whenever you feel like criticizing anyone,' he told me, 
'just remember that all the people in this world haven't had the advantages that you've had.'</p>
<p><b>Note:</b> Resize the browser window to see how the value "justify" works.</p>
</body>

In my younger and more vulnerable years my father gave me some advice that I've been turning over in my mind ever since. 'Whenever you feel like criticizing anyone,' he told me, 'just remember that all the people in this world haven't had the advantages that you've had.'
Note: Resize the browser window to see how the value "justify" works


Text Decoration

The text-decoration property is used to set or remove decorations from text.
The text-decoration property is mostly used to remove underlines from links for design purposes:

Example

<html>
<head>
<style type="text/css">
a {text-decoration:none;}
</style>
</head>

<body>
<p>Link to: <a href="http://www.amaderit.com.com">Amader IT</a></p>
</body>

</html>

Try it yourself in Notepad or Dreamweaver by coping and pasting the code above.
Result:
Link to: Amader IT

It can also be used to decorate text:

Example

<html>
<head>
<style type="text/css">
h1 {text-decoration:overline;}
h2 {text-decoration:line-through;}
h3 {text-decoration:underline;}
h4 {text-decoration:blink;}
</style>
</head>

<body>
<h1>This is heading 1</h1>
<h2>This is heading 2</h2>
<h3>This is heading 3</h3>
<h4>This is heading 4</h4>
<p><b>Note:</b> The "blink" value is not supported in IE, Chrome, or Safari.</p>
</body>

</html>

Try it yourself in Notepad or Dreamweaver by coping and pasting the code above.
Result:

This is heading 1

This is heading 2

This is heading 3

This is heading 4

Note: The "blink" value is not supported in IE, Chrome, or Safari.


Remark It is not recommended to underline text that is not a link, as this often confuses users.

Text Transformation

The text-transform property is used to specify uppercase and lowercase letters in a text.
It can be used to turn everything into uppercase or lowercase letters, or capitalize the first letter of each word.

Example

<html>
<head>
<style type="text/css">
p.uppercase {text-transform:uppercase;}
p.lowercase {text-transform:lowercase;}
p.capitalize {text-transform:capitalize;}
</style>
</head>

<body>
<p class="uppercase">This is some text.</p>
<p class="lowercase">This is some text.</p>
<p class="capitalize">This is some text.</p>
</body>
</html>

Try it yourself in Notepad or Dreamweaver by coping and pasting the code above.
Result:

THIS IS SOME TEXT.
this is some text.
This Is Some Text.


Text Indentation

The text-indentation property is used to specify the indentation of the first line of a text.

Example

<html>
<head>
<style type="text/css">
p {text-indent:50px;}
</style>
</head>
<body>

<p>In my younger and more vulnerable years my father gave me some advice that I've been turning over in my mind ever since. 'Whenever you feel like criticizing anyone,' he told me, 'just remember that all the people in this world haven't had the advantages that you've had.'</p>
