Hey Ian,
you can use
#footer {
margin-top: 0px;
position: fixed;
bottom: 0px;
}
to force it to stick to the bottom on all pages, yet the catch here is that the „bottom” will be defined as the bottom of the browser window – i.e. if the page’s content exceeds the window height, the footer will overlap it. Without resorting to hacky solutions, it’s possible to either tell the footer to consider the bottom of the screen as its starting point, or the bottom of content, not both. This is why there’s no content block on the „Page with Background Slider” page template.
Sincerely,
