LESS - Variable Lazy Loading

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.

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