The Less Merge Space feature is used to add property value with space. It appends property value with space.

Let's take an example to demonstrate the usage of merge space feature in Less file.

Create a HTML file named "simple.html", having the following data.

HTML file: simple.html

  1. <!DOCTYPE html>  
  2. <head>  
  3.    <title>Merge Space Example</title>  
  4.    <link rel="stylesheet" href="simple.css" type="text/css" />  
  5. </head>  
  6. <body>  
  7.    <h2>Example of Merge Space</h2>  
  8.    <p class="class">Welcome to JavaTpoint: A solution of all technology.</p>  
  9. </body>  
  10. </html>  

Now create a file named "simple.less". It is similar to CSS file. The only one difference is that it is saved with ".less" extension.

Less file: simple.less

  1. .mixin() {  
  2.   transform+_: scale(1);  
  3. }  
  4. .class {  
  5.   .mixin();  
  6.   transform+_: rotate(2deg);  
  7. }   

Put the both file "simple.html" and "simple.less" inside the root folder of Node.js

Now, execute the following code: lessc simple.less simple.css

Less Less merge space1

This will compile the "simple.less" file. A CSS file named "simple.css" will be generated.

For example:

Less Less merge space2

The generated CSS "simple.css", has the following code:

  1. .class {  
  2.   transform: scale(1) rotate(2deg);  
  3. }   

Output:

Less Less merge space3
