Using Background Images

Background images make the blog so much more colourful than plain old solid colour backgrounds. A background image

• Is not clickable.
• Shows up only where no foreground content is present.

Look at using a background image under the text title, for instance. Note that this is the opposite from replacing the text in the title with a picture. If you put a picture in the title, no background will be visible, unless you intentionally make the picture too small for the title space, or use a transparent .gif file for an image.

We do this using CSS rules. Look in the template for

#header-wrapper {
width:660px;
margin:0 auto 10px;
border:0px solid $bordercolor;
}

Change that to

#header-wrapper {
width:660px;
margin:0 auto 10px;
border:0px solid $bordercolor;
background: url(http://whatever.wherever.com/what.gif) no-repeat 0px 0px;
}

The CSS object "header-wrapper" is the Beta standard name for the screen area which will contain the text blog title and blog description. If you have, separately, tweaked your header, any of the above settings may differ. Just add the "background" rule.

If you have a Classic blog, your template may or may not use a CSS rule to define the header. It may or may not use a CSS object "header-wrapper". Be aware of the possibilities. You could, conceivably, have a <div> tag, with all of the rules defined there in the HTML.

<div style="width:660px; margin:0 auto 10px; border:0px solid $bordercolor;"> ... </div>

if so, change that to

<div style="width:660px; margin:0 auto 10px; border:0px solid $bordercolor;background: url(http://whatever.wherever.com/what.gif) no-repeat 0px 0px;"> ... </div>

You can apply a background image to any area in the blog, not just the header.

body {
...
background: url('whatever.wherever.com/what.gif');
...
}

With any large screen area, your image will probably be smaller than the area being covered. You'll probably not use "norepeat", so your background image gets reused, repeatedly, in a checkerboard pattern, over the entire area.
