LESS - Not Outputting The Mixin

Description

It is possible to create a mixin and it can be made to disappear in the output by simply placing the parentheses after it.

Example

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

<html>
   <head>
      <link rel = "stylesheet" href = "style.css" type = "text/css" />
      <title>LESS Mixins</title>
   </head>

   <body>
      <div class = "myclass">
         <h1>Welcome to Tutorialspoint</h1>
         <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

.a() {
   padding-left: 100px;
}

.myclass {
   background : #64d9c0;
   .a;
}

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 {
   background: #64d9c0;
   padding-left: 100px;
}
