HTML comments are used to add notes or remarks that are not displayed on the webpage. They can be used to provide explanations or instructions for other developers who may be working on the code, or simply to remind yourself of things you need to fix or improve later.
To add a comment in HTML, you can use the
<!-- --> syntax. Anything you put between these tags will not be displayed on the webpage. Here’s an example:
<!-- This is a comment. It will not be displayed on the webpage. --> <p>This is some text that will be displayed on the webpage.</p> <!-- Here's another comment. -->
In this example, the first and third lines are comments, while the second line contains actual HTML code that will be displayed on the webpage.
Comments can also be used to temporarily remove code from the page without deleting it entirely. For example, if you’re troubleshooting a problem with your code, you might comment out certain lines to see if that fixes the issue. Here’s an example:
<!-- <p>This line of code is causing a problem.</p> --> <p>This line of code is not causing a problem.</p>
In this example, the first line has been commented out so that it is temporarily disabled. This can help you isolate the problem and determine if the issue is caused by that particular line of code.
It’s important to note that comments should be used sparingly and only when necessary. Overuse of comments can make the code difficult to read and maintain, especially if the comments are not kept up-to-date as the code changes over time.
