LESS - Classic Use Case

Description

Classic use case is used to keep away adding the base class in LESS. The values written in base class are avoided when the same values are overridden inside the other class.

Example

The below example describes the use of classic use case in the LESS file −

extend_syntax.htm

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

   <body>
      <div class = "cont">
         <h2>Welcome to TutorialsPoint</h2>
         <p>The largest Tutorials Library on the web.</p>
      </div>
   </body>
</html>

Next, create the style.less file.

style.less

.style {
   font-family: "Times New Roman";
   font-style:italic;
}

.cont {
   &:extend(.style);
   font-family: "Comic Sans MS";
}

You can compile the style.less file 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

.style,
.cont {
   font-family: "Times New Roman";
   font-style: italic;
}

.cont {
   font-family: "Comic Sans MS";
}

Output

Follow these steps to see how the above code works −

  • Save the above html code in the extend_syntax.htm file.

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