How to add comments in HTML

Theodore Kelechukwu Onyejiaku

In programming or coding, comments provide readability, understandability, clarifications, helpful notes, and so on. It is a good practice to add comments in your code. While writing HTML, you can also add comments.

Syntax

<!-- [comment] -->

HTML comments begin with the <!-- tag and are closed with the --> tag.

Note: The opening tag has an exclamation mark, but the closing tag does not.

Examples

Just like in other languages, comments can be single-line or multi-line. In HTML, we use the same syntax for both.

<!-- This is a single line comment -->

<!-- This is a 
multi-line comment
in HTML-->

Demo

Let’s demonstrate the use of a comment in HTML in the following code by making sure that only one p element is displayed on the browser.

<!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="UTF-8">
        <meta http-equiv="X-UA-Compatible" content="IE=edge">
        <meta name="viewport" content="width=device-width, initial-scale=1.0">
        <title>HTML Comment</title>
    </head>
    <body>
        <p>This paragraph should display</p>
        <!-- Hey browser don't display this
        <p>This paragraph should not display yet</p>
        -->
    </body>
</html>

Thanks for reading!
