LESS - Mixin inside mixin

Description

Whenever a mixin is defined inside another mixin, it can be used as return value too.

Example

The following example demonstrates the use of mixin inside mixin in the LESS file −

<html>
   <head>
      <link rel = "stylesheet" href = "style.css" type = "text/css" />
      <title>Mixin inside mixin</title>
   </head>

   <body>
      <h1>Welcome to Tutorialspoint</h1>
      <div class = "myclass">
         <p>LESS is a CSS pre-processor that enables customizable, 
         manageable and reusable style sheet for web site.</p>
      </div>
   </body>
</html>

Next, create the style.less file.

style.less

.outerMixin(@value) {
   .nestedMixin() {
      font-size: @value;
   }
}

.myclass {
   .outerMixin(30);
   .nestedMixin();
}

You can compile the style.less to style.css by using the following command −

lessc style.less style.css

Execute the above command; it will create the style.css file automatically with the following code −

style.css

.myclass {
   font-size: 30;
}
