Example

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

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

   <body>
      <h2>Exclusion Function</h2>
      <div class = "color1">
         <p>(color1) <br> #ff6600</p>
      </div><br>
      
      <div class = "color2">
         <p>(color2) <br> #333333</p>
      </div><br>
      
      <div class = "res">
         <p>(result) <br> #cc7033</p>
      </div>
   </body>
</html>

Next, create the style.less file.

style.less

.color1 {
   width: 100px;
   height: 100px;
   background-color: #ff6600;
}

.color2 {
   width: 100px;
   height: 100px;
   background-color: #333333;
}

.res {
   width: 100px;
   height: 100px;
   background-color: exclusion(#ff6600, #333333);
}

p {
   padding: 30px 0px 0px 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

.color1 {
   width: 100px;
   height: 100px;
   background-color: #ff6600;
}

.color2 {
   width: 100px;
   height: 100px;
   background-color: #333333;
}

.result {
   width: 100px;
   height: 100px;
   background-color: #cc7033;
}

p {
   padding: 30px 0px 0px 25px;
}
