The new Blogger templates are somewhat different from the older ones. In the older templates you would change the background in the Edit HTML section of your template, under the body {. If you are using a new template you can change it though the template designer.
1. To change the background of a new Blogger template to a custom design you need to go to Design --> Template Designer --> Advanced --> Add CSS.
2. Once you are there you need to insert a code like the one below:
background: url(http://www.example.com/image.png)PV RV;
background-attachment: AV;
}
.body-fauxcolumn-outer div {
background: none;
}
RED: This is the image URL.
BLUE: This is the positioning variable.
CYAN: This is the repeat variable.
GREEN: This is the attachment variable.
Now I am going to explain the variables and their purpose.
Positioning Variables (PV):
This is the position of the image in relation to the center of the element (in this case your whole screen). You can use any one of the following variables:
* top left
* top center
* top right
* center left
* center center
* center right
* bottom left
* bottom center
* bottom right
Repeat Variables (RV):
They specify how the image repeats itself.
*repeat (Repeats Y and X also known as tiled)
*repeat-x (Repeats Horizontal)
*repeat-y (Repeats Vertical)
*no-repeat (No repeat)
Attachment Variables (AV):
They specify whether the image moves with the screen when your scroll or whether it stays in place.
*fixed (Stays in place)
*scroll (Scrolls with screen)
3. After you are done the code may look like the one below:
background: url(http://www.example.com/image.png)top center repeat-x;
background-attachment: fixed;
}
.body-fauxcolumn-outer div {
background: none;
}
Note: Some newer templates may have conflicting elements that may cause the background to not work as planned.
Here are a couple of templates that need different code from the one used in the instructions. If you are using one of these template you may have to insert the codes below.
Watermark 3 Template: (grassy background image)
background: none;
}
.main-outer {
background: none;
}
body {
background: none;
}
.main-cap-top .cap-right{
background: none;
}
.body-fauxcolumn-outer {
background: url(http://www.example.com/image.png) PV RV;
background-attachment: AV;
}
Simple Template and Watermark Template:
background: url(http://www.example.com/image.png) PV RV;
background-attachment: fixed;
}
.body-fauxcolumn-outer .cap-top {
background: url(http://www.example.com/image.png) PV RV;
background-attachment: fixed;
}
The positioning variables and repeat variables must be the same for both. The attachment must be set to fixed. You don't necessarily have to follow this, and you can use 2 different images for a custom design. However, this is what I had to do to get a single image to display correctly.
That´s all!
Good luck!
