LESS - Selector Interpolation with Extend

Description

The @{variable} symbol is used as part of the variable name, id and class name. Extend does not have the ability to match selector with variables. Extend can be connected to the interpolated selector.

Example

The following example demonstrates the use of selector interpolation with extend in the LESS file −

extend_syntax.htm

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

   <body>
      <h2 class = "style">This is a simple example of Selector Interpolation</h2>
      <p class = "style">This is a simple example of Selector Interpolation</p>
   </body>
</html>

Next, create the style.less file.

style.less

.style {
   color: #BF70A5;
   font-style: italic;
}
@{variable}:extend(.style) {}
@variable: .selector;

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,
.selector {
   color: #BF70A5;
   font-style: italic;
}

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.
