LESS - Extend Inside Ruleset

Description

The &:extend(selector) syntax can be put inside the body of ruleset. It is shortcut of placing extend into every single selector of the ruleset.

Example

The following example demonstrates the use of extend inside ruleset in the LESS file −

extend_syntax.htm

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

   <body>
      <div class = "style">
         <h1>Welcome to TutorialsPoint</h1>
         <div class = "container">
            <h2>Hello!!!!!</h2>
         </div>
      </div>
   </body>
</html>

Next, create the style.less file.

style.less

.container,
.style {
   &:extend(.img);
}

.img{
   font-style: italic;
   background-color: #7B68EE;
}

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

.img,
.container,
.style {
   font-style: italic;
   background-color: #7B68EE;
}
