body Preloader
If Preloader is enabled an animated loader will show before the actual page can be viewed. your pages will be loaded in the background giving a delay of around 3 seconds before the loaded page will be shown. This is useful if you have slower page load times in some circumstances (for instance slow loading images).

No Repeat will show an image in it's original state and will set at the top left of a page without a background-position.
Repeat All will repeat the same image horizontally and vertically seamlessly over the full page. The last image will be clipped if it does not fit. This is ideal for small images with certain shapes, designs, or colors.
Repeat Horizontally will repeat the image across a page.
Repeat Vertically will repeat the image down a page.

Background Size

Inherit background size gets it's value from its parent element.
Cover resizes the background image to cover the entire container, even if it has to stretch the image or cut a little bit off one of the edges.
Contain resizes the background image so the image is fully visible.
