Description

In lazy loading, variables can be used even when they are not declared.

Example

The following example demonstrates the use of lazy loading of variable in the LESS file −

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

   <body>
      <h2>Welcome to Tutorialspoint</h2>
      <p>LESS is a CSS pre-processor.</p>
   </body>
</html>

Now create the style.less.

style.less

p {
   font-size: @a;
   color: #ca428b;
}
@a: @b;
@b: 25px;

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

p {
   font-size: 25px;
   color: #ca428b;
}

Output

Follow these steps to see how the above code works −

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