About Scopes

You may have tailwind classes in other places besides className="...", or even cva(...). For examples, the classes prop in mui components.

You can define places for cnls to look for classes with the cnls.scopes settings. The syntax for a scope is :<...values>

Variants are:

• fn to target a function call (e.g 'fn:cva')
• att to target a jsx attribute (e.g. 'att:className')
• prop to target a jsx attribute (e.g. 'prop:className')

Values are strings, and you can use a wildcard * at the begining or the end. For example 'att:className att:*ClassName' will find classes all of these attributes

<Btn
  className="w-10 bg-red"
  iconClassName="text-black"
  textClassName="text-xl"
/>

By default cnls uses 'att:className,class fn:createElement'.
