HTML Comment Tag
The HTML comment tag is a markup construct used to add comments to an HTML document. Comments are not displayed in the web browser and are meant for developers to provide notes, explanations, or instructions to other developers who may be working on the same code.
In HTML, comments are delimited by the <!--
and -->
characters. Anything between these characters will be ignored by the browser and will not be displayed in the rendered webpage. Here’s an example of how to use the comment tag in HTML:
<!-- This is a comment -->
<p>This is some text.</p>
<!-- <p>This paragraph is commented out.</p> -->
In this example, the first and third lines are comments, while the second line is a paragraph of text. The third line also includes a commented-out paragraph, which is not rendered by the browser.
Comments can be used to explain the purpose or function of specific sections of code, to provide reminders or warnings, or to temporarily disable code during development. Here’s an example of how comments might be used to explain a piece of code:
<div class="container">
<!-- This div contains the header of the page -->
<header>
<h1>Welcome to my website!</h1>
<nav>
<!-- Navigation links go here -->
</nav>
</header>
<!-- Main content area -->
<main>
<p>This is some text.</p>
<!-- <p>This paragraph is commented out for now.</p> -->
</main>
</div>
In this example, comments are used to explain the purpose of the div elements, header, and main sections of the HTML code.
In summary, the HTML comment tag is used to add comments to an HTML document that are ignored by the browser and not displayed in the rendered webpage. Comments are useful for developers to provide notes, explanations, or instructions to other developers working on the same code. They are delimited by the <!--
and -->
characters and can be used to explain the purpose or function of specific sections of code, provide reminders or warnings, or temporarily disable code during development.
