A comment tag is a HTML tag that is used to add comments to a HTML page. A HTML comment tag must have:
- <!– at the beginning of the comment.
- Text or HTML markup in between.
- –> at the end of the comment.
An example of a single-line HTML comment tag is:
<!-- This is a single line HTML comment -->
If you want to comment out a whole HTML section, you can use a multi-line HTML comment as shown below:
<!-- This is a multi-line HTML comment It contains a lot of HTML content inside it. <div id="header"> <h1 id="my-logo" class="title">Picture learner</h1> --> <h2 class="subtitle">Learn through pictures and sounds</h2> </div>
Any text inside the comment tag is not visible to the reader on the browser. You can view the comments when you click: “view page source” on a browser.
You can use the comment tags to:
- insert comments in the source code
When you are writing the HTML code, you can use the comment to explain what each section of the code is doing.
- hide part of a webpage from being displayed.
You can use HTML comment tag to comment out HTML code. If you have a part of a webpage that you want to hide it but not delete it, then HTML comment tag is your best bet. This way, you can hide a whole section of a HTML page from being viewed on the browser.
You can use comments to explain your code, which can help you when you edit the source code at a later date. This is especially useful if you have a lot of code.
