HTML comments are used to add notes or remarks to the HTML code. These comments are not displayed in the web browser, but they can be useful for developers to understand the code or to leave reminders for themselves or other developers.
HTML comments are written using the <!-- and --> tags. Anything written between these tags is considered a comment and is ignored by the web browser.
Here are some examples of how to use HTML comments:
<!-- This is a comment --> <p>This is some text.</p> <!-- This is a multi-line comment. It can span multiple lines. -->
As you can see, comments can be added anywhere in the HTML code, and they can be single-line or multi-line.
Comments can also be used to temporarily remove or "comment out" a piece of code without deleting it. This can be useful for testing or debugging purposes.
Here is an example of how to use comments to temporarily remove a piece of code:
<p>This is some text.</p> <!-- <p>This is some other text.</p> -->
In this example, the second <p> tag is commented out, so it will not be displayed in the web browser.
It is important to note that comments should not be used to hide or obfuscate code. They should only be used for notes or remarks that are relevant to the code.
Overall, HTML comments are a useful tool for developers to add notes or remarks to their code without affecting the display of the web page.
