Modify Site Background Image or Colour

If you want to change your UnionCloud sites' Background Image, or Background Colour, and you have access to Global CSS you can do either of these things using the following lines of code:

body { 
    background: url(https://pathToImage.jpg) no-repeat center center fixed; /*FOR AN IMAGE*/
OR
background-color:color; /*FOR A COLOR*/
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: cover;
}
