Backgrounds (Css tutorial)

Hello guys! morning and welcome to this section of my tutorial. In my last tutorial i talked about CSS Measurement Units. So now i want to talk about CSS backgrounds.
This section of my tutorial teaches you how to set backgrounds of various HTML elements. You can set the following background properties of an element:

  • The background-color property is used to set the background color of an element.
  • The background-image property is used to set the background image of an element.
  • The background-repeat property is used to control the repetition of an image in the background.
  • The background-position property is used to control the position of an image in the background.
  • The background-attachment property is used to control the scrolling of an image in the background.
  • The background property is used as a shorthand to specify a number of other background properties.
Set the Background Color
Following is the example, which demonstrates how to set the background color for an element.

<p  style="background-color:blue;">
This text has a blue background color.
</p>

Set the Background Image

<table  style="background-image:url(/image/novapic.gif);">
<tr>
<td>
This table has background image set.
</td>
</tr>
</table>

Repeat the Background Image
The following example demonstrates how to repeat the background image if an image is small. You can use no-repeat value for the background-repeat property if you don't want to repeat an image. In this case, the image will display only once. 
By default the background-repeat property will have a repeat value.

<table  style="background-image:url(/image/novapic.gif);  
                        background-repeat: repeat;">
<tr>
<td>
This table has background image which repeats multiple times.
</td>
</tr>
</table>

The following example which demonstrate how to repeat background image vertically.

<table  style="background-image:url(/image/novapic.gif);  
                        background-repeat: repeat-y;">
<tr>
<td>
This table has background image set which will repeat vertically.
</td>
</tr>
</table>

The following example demonstrate how to repeat the background image horizontally.

<table  style="background-image:url(/image/novapic.gif);  
                        background-repeat: repeat-x;">
<tr>
<td>
This table has background image set which will repeat horizontally.
</td>
</tr>
</table> 

Set the Background Image Position
The following example demonstrates how to set the background image positioned 150 pixels away from the left side.

<table  style="background-image:url(/image/novapic.gif);  
                        background-position: 150px;">
<tr>
<td>
This table has background image positioned 150 pixels away from the left.
</td>
</tr>
</table> 

The following example demonstrates how to set the background image positioned 150 pixels away from the left side and 200 pixels down from the top.

<table  style="background-image:url(/image/novapic.gif);  
                        background-position: 150px  200px;">
<tr>
<td>
This table has background image positioned 150 pixels away from the left and 200 pixels down from the top.
</td>
</tr>
</table> 

Set the Background Attachment
Background attachment determines whether a background image is fixed or  scrolls with the rest of the page.
The following example demonstrates how to set the fixed background image. 

<p  style="background-image:url(/image/novapic.gif);  
                        background-attachment: fixed;">

This paragraph has a fixed background image.
</p> 

The following example demonstrates how to set the scrolling background image.

<p  style="background-image:url(/image/novapic.gif);  
                        background-attachment: scroll;">

This paragraph has a scrolling background image.
</p>

Shorthand Property
You can use the background property to set all the background properties once. For example:

<p style="background:url(/image/novapic.gif)" repeat fixed;">
This paragraph has fixed repeated background image.
</p>
