LESS will call mixin dynamically

What do you call mixin dynamically?

A use case may be to create a style guide:

// The mixin which should be called
.typography-xs(){
  font-family: Arial;
  font-size: 16px;
  line-height: 22px;
}

// The mixin which tries to call typography-xs
.typography-demo(@typographyName, @mixinName) {
  @{typographyName} {
    &:before{content: '@{typographyName}';}
    // Calling the mixin dynamically
    @mixinName();
  }
}

// Example call of .typograhpy-demo
.typography-demo(xs, typography-xs);

Is such a dynamic call possible with a lower css value?

Currently, you cannot dynamically call as you wish. You can, however, customize it a little differently using pattern matching , for example:

// The mixin which should be called
.typography(xs){
  font-family: Arial;
  font-size: 16px;
  line-height: 22px;
}

// The mixin which tries to call typography-xs
.typography-demo(@typographyName) {
  @{typographyName} {
    &:before{content: '@{typographyName}';}
    // Calling the mixin dynamically
    .typography(@typographyName);
  }
}

// Example call of .typograhpy-demo
.typography-demo(xs);

Using pattern matching, you can create other patterns, for example:

.typography(xl){
  font-family: Arial;
  font-size: 32px;
  line-height: 44px;
}

.typography(times){
  font-family: 'Times New Roman';
  font-size: 16px;
  line-height: 22px;
}

xl times . , , (, -xs), , mixins.

, @{typographyName} :

.typography-demo(@typographyName, @selector: ~".") {
  @{selector}@{typographyName} {
    &:before{content: '@{typographyName}';}
    // Calling the mixin dynamically
    .typography(@typographyName);
  }
}

, , id @{typographyName}.
