Stylesheet Variables

Has anyone managed to get these working in Contao 2.11.2?

I'm trying but it doesn't seem to be working for me. Here's an example:

In the global stylesheet options for my theme I put '$blue1' into the Key field and then 2e3192 into the Value field.

In my actual stylesheet I then use the variable like this:

Code:

---

#wrapper
{
    background:#$blue1;
}

---

It's not working though.Is that right? I've tried all sorts of things like not including the '$' in the Key field and including the # in the Value field. When I check the style in my browser it's actually outputting the variable name instead of the value.

Update: I've managed to get it working by declaring the variables for each stylesheet individually, but the global values are still not working.

I need to global values to work as I have about 15 styelsheets, it defeats the point of using variables if I have to go and set-up the variables for each stylesheet.

Update: Cleared the Contao cache under Maintenance and it has cured the problem.
