Basic HTML Comments

Comments in HTML are created using the <!-- --> syntax. Anything between these markers is considered a comment and will not be rendered by the browser:

<!-- This is a comment -->

Using Comments to Explain Code

Comments can be used to explain the purpose of an HTML element, making the code easier to understand for anyone who might read it in the future:

<!-- This paragraph contains a brief description of the article -->
<p>This is a short paragraph explaining the content of the article.</p>

Commenting Out Code

Comments can also be used to temporarily disable parts of the HTML code during testing. This is useful for debugging or testing the effects of excluding certain elements:

<!--
<p>This paragraph will not be displayed in the browser because it is commented out.</p>
-->

Nesting Comments

Nesting comments, or placing comments within comments, is not supported in HTML. Attempting to nest comments can lead to unexpected results and is generally discouraged:

<!-- This is a comment
    <!-- This nested comment will cause an error -->
-->
