Retrieving and Using Variables

Frink

I am building an extension, and I am trying to save the variable from the admin settings modal, then echo it into an extension.less file with some css styling. My question is:

Where would I define the name for the variable?
How would I pull the variable?
How would I echo the variable, and other text into my .less file?

Frink The best examples are always .. other extensions. The one I know is flarum/core which uses the user defined colors to generate the whole css; you might want to spit through that first?

luceos OK. How do I name my variables, and how would I reference them in JS, and also PHP?
