Changing Backgrounds
To add or change a background on your website, navigate here. Click on whichever template you are in. It will have a star beside it. TIP: If you are in a Custom template, you would choose that instead of Default.
Go into Manage Styles for the Body Container.
If this is a new background, you will need to create a style called .sitecontainer
If you already have one, you will just need to edit the style that is already there.
Apply it to Medium and Large. Click on the background tab. Upload an image.
There are a few options on the right hand side. You may need to adjust a few of these depending on the size of your image. Hit Update.
