LESS - List Extract Function

Description

It will return the value at a specified position in a list. It takes list (list of values separated by a comma or space) and index (integer specifying a position of an element to return) as parameters.

Example

The following example demonstrates the use of extract function in the LESS file −

<!doctype html>
   <head>
      <title>Extract Function</title>
      <link rel = "stylesheet" href = "style.css" type = "text/css" />
   </head>

   <body>
      <h1>Example of Extract Function</h1>
      <p>LESS enables customizable, manageable and reusable style sheet for web site.</p>
   </body>
</html>

Next, create the style.less file.

style.less

p {
   @list: 10px, 20px, 30px, 40px;
   @val: extract(@list, 2);
   font-size:@val;
   color:#F79F81;
}

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: 20px;
   color: #F79F81;
}
