Less.js is a simple CSS pre-processor that facilitates the creation of manageable, customizable, and reusable style sheets for websites. Because of this dynamic style sheet language, CSS is more useful. Interoperability between browsers is a characteristic of LESS. The CSS pre-processor is a computer language that is used to augment and compile CSS so that web browsers may use it. In addition, it is an extension to the CSS language that offers features like variables, functions, mixins, and operations that enable us to develop dynamic CSS while maintaining backward compatibility.

Compile LESS code into CSS code using the link.
Example 1: The code below demonstrates the usage and implementation of the Color Channel green() function.
<!DOCTYPE html> <html>
<head>
<link rel="stylesheet" type="text/css" href="style.css"/>
</head>
<body>
<h1 style="color:green">GeeksforGeeks</h1>
<h3><b>Less.js Color Channel
green() Function</b></h3>
<div class="container">
<p class="text">Box</p>
</div>
</body>
</html>
|
@body-bg-color: #eeeeee;
@text-color: rgb(0, 200, 100);
@container-bg: rgb(220, 43, 55);
body { background: @body-bg-color;
} .container{ height:100px;
width: 100px;
padding: 30px 0px 0px 25px;
background-color: (#cc3eff);
color:yellow;
} .text{ font-weight: green(rgb(123, 200, 0));
} |
Now, to compile the above LESS code to CSS code, run the following command:
lessc styles.less styles.css
The compiled CSS file comes to be:
body { background: #eeeeee;
} .container { height: 100px;
width: 100px;
padding: 30px 0px 0px 25px;
background-color: #cc3eff;
color: yellow;
} .text { font-weight: 200;
} |
Output:
Example 2: The code below demonstrates the usage and implementation of the Color Channel green() function with the if and boolean logical functions.
<!DOCTYPE html> <html>
<head>
<link rel="stylesheet" type="text/css" href="style.css"/>
</head>
<body>
<h1 style="color:green">GeeksforGeeks</h1>
<h3><b>Less.js Color Channel

@body-bg-color: #eeeeee;
@text-color: rgb(80, 188, 134);
@container-bg: rgb(255, 178, 24);
@cond1: boolean(green(@text-color) < 50%);
body { background: @body-bg-color;
} .container{ height:100px;
width: 150px;
padding: 30px 0px 0px 25px;
background-color: #6a001e;
color:yellow;
} .text{ font-weight: if(@cond1, bold, bolder);
} |
Now, to compile the above LESS code to CSS code, run the following command:
lessc styles.less styles.css
The compiled CSS file comes to be:
body { background: #eeeeee;
} .container { height: 100px;
width: 150px;
padding: 30px 0px 0px 25px;
background-color: #6a001e;
