About CSS

In this lesson, we will learn about the CSS comments and its usages.

Understanding and Using CSS Comments

CSS comments are essential for documenting your code, making it more readable, and providing notes for yourself or other developers who may work with your code.

Comments in CSS are messages or explanations that are not displayed in the webpage but are visible in the source code. They help you explain your design decisions, mark sections of code, or temporarily disable styles for testing.

In CSS, comments are written using the following syntax:

Syntax
/* This is a CSS comment */

Comments start with /* and end with */. Everything between these symbols is considered a comment and is ignored by the browser when rendering the webpage.

Why Use CSS Comments

You can use comment in your CSS code for the following reasons and they are:

  • Documentation: Comments serve as documentation for your CSS code. They explain why you made specific design choices, helping you and others understand the code's purpose.
  • Debugging: Comments can help identify issues or debug problems in your styles. You can comment out sections of code to see how changes affect your design.
  • Temporary Changes: You can use comments to temporarily disable styles without removing the code. This is helpful for testing or troubleshooting.

Let's look at some common use cases for CSS comments:

Explaining Styles:
/* Set the font size for headings to 24px */
h1, h2, h3, h4, h5, h6 {
    font-size: 24px;
}
Section Marking:
/* ================
   Header Styles
   ================ */
.header {
    background-color: #333;
    color: #fff;
}
Temporary Disabling:
/* Comment out this code to disable the background color */
/* background-color: #ff0000; */
