Comments - (Less Basics)

Comments are an important part of any programming language. They allow you to add notes and explanations to your code that can help other developers understand what you are doing. In this tutorial, we'll discuss how to add comments in Less.

Syntax

In Less, there are two ways to add comments:

// This is a comment

/* This is a
 * multi-line
 * comment
 */

The // syntax is used for single-line comments, while the /* */ syntax is used for multi-line comments.

Example

Let's add some comments to a Less file:

// Define some colors
@primary-color: #428bca; // Blue
@secondary-color: #d9534f; // Red

/* 
   Mixin for generating
   box shadows
*/
.box-shadow(@x: 0, @y: 0, @blur: 4px, @color: #000000) {
  box-shadow: @arguments;
  -moz-box-shadow: @arguments;
  -webkit-box-shadow: @arguments;
}

// Usage
.my-element {
  background-color: @primary-color;
  color: @secondary-color;
  .box-shadow(0, 0, 8px);
}

In this example, we define some colors and a mixin for generating box shadows. We also add some comments to explain what the code does and how to use it.

Output

Comments in Less are ignored by the compiler and do not appear in the compiled CSS. They are only there to help you and other developers understand the code.

Explanation

Less supports both single-line and multi-line comments. Single-line comments start with // and continue until the end of the line. Multi-line comments start with /* and end with */. Multi-line comments can span multiple lines and can be used for longer explanations and notes.

Use

Comments are an important part of writing clean and maintainable code. They allow you to add notes and explanations that can help other developers understand your code. Use comments to describe what your code does, why it does it, and how to use it.

Important Points

• Comments in Less start with // for single-line comments and /* */ for multi-line comments.
• Comments are ignored by the compiler and do not appear in the compiled CSS.
• Use comments to describe what your code does, why it does it, and how to use it.

Summary

In this tutorial, we discussed how to add comments in Less. We covered the syntax, example, output, explanation, use, and important points of Less comments. With this knowledge, you can now add comments to your Less code to make it easier to understand and maintain.
