Variables
How to use variables?
You just have to write your variables in the [ExtendedCSS] tag like this:
[ExtendedCSS]
var1="grey"
yourVar="white"
test_var="monospace"
Then you can use your variables in the css file like this:
body {
background-color: $var1;
color: $yourVar;
font-family: $test_var;
}
