LESS - Greyscale

Description

It discards the saturation from a color in the selected elements. It has the following parameters −

color − It represents a color object.

Example

The following example demonstrates the use of greyscale color operation in the LESS file −

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

   <body>
      <h2>Example of Greyscale Color Operation</h2>
      <div class = "myclass1">
         <p>color :<br>#426105</p>
      </div><br>

      <div class = "myclass2">
         <p>result :<br>#333333</p>
      </div>
   </body>
</html>

Next, create the style.less file.

style.less

.myclass1 {
   height:100px;
   width:100px;
   padding: 30px 0px 0px 25px;
   background-color: hsl(80, 90%, 20%);
   color:white;
}

.myclass2 {
   height:100px;
   width:100px;
   padding: 30px 0px 0px 25px;
   background-color: greyscale(hsl(80, 90%, 20%));
   color:white;
}

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

.myclass1 {
   height: 100px;
   width: 100px;
   padding: 30px 0px 0px 25px;
   background-color: #426105;
   color: white;
}

.myclass2 {
   height: 100px;
   width: 100px;
   padding: 30px 0px 0px 25px;
   background-color: #333333;
   color: white;
}
