LESS - Mixin & return values


Mixins are similar to functions and the variables that are defined in a mixin will behave as its return values.


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

      <link rel = "stylesheet" href = "style.css" type = "text/css" />
      <title>Mixins & return values</title>

      <div class = "myclass">
         <h2>Welcome to Tutorialspoint</h2>
         <p>LESS is a CSS pre-processor that enables customizable, 
         manageable and reusable style sheet for web site.</p>

Next, create the style.less file.


.padding(@x, @y) {
   @padding: ((@x + @y) / 2);

   .padding(80px, 120px);  // call to the mixin
   padding-left: @padding; //  returns the value

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 −


.myclass {
   padding-left: 100px;


Follow these steps to see how the above code works −

  • Save the above html code in the less_Mixin_as_function_return_values.html file.

  • Open this HTML file in a browser, the following output will get displayed.
