We have an option for this in CSS Sculptor that you can add to any layout.
Here's the CSS we use:
/* The following code is for the fixed footer */
html, body {
height: 100%;
}
#outerWrapper {
min-height: 100%;
position: relative;
}
* html #outerWrapper {
height: 100%;
}
#outerWrapper #fixedFooterWrapper {
bottom: 0;
position: absolute;
width: 100%;
}
You'll need to wrap your standard footer div with an outer wrapper to work properly.
