Assuming I have the following mixin with following arguments:
.font-style(@size: 1.2em, @style: 100, @leading:1.4em, @color: #efefed)
Now I want to play this mixin passing the arguments that I define for a specific class. Ex:
.myClass{ .font-style(2.2em,...) }
Doubt : If I want to modify only the @size and @color arguments, I'd need to repeat the default (@arguments) of the order Ex:
.font-style( @==a -> "mudei valor", @==b "default", @==c "default", @==d -> "mudei valor )
Yes, when creating your mixin with parameters using the variable "@arguments" you must specify a default value for each of them.
So when calling your mixin you do not have to pass the values in a special order and even omit the defaults. Ex:
Set Mixin
.font-style(@size: 1.2em, @style: 100, @leading:1.4em, @color: #efefed);
Call Mixin
.myClass{ .font-style(2.2em,2.4em) }
Note the omission of the other parameters.
Optional parameters (non-explicit value) need to be passed when there is a call. Ex:
.font-style(@size: @size, @color: @color);
