How to Comment in HTML

Author Info

Last Updated: January 18, 2023 Tested

A comment is a line of code that is not read by web browsers. Commenting your code allows you to leave reminders and explanations for yourself and any other coder that will be working on the page. Commenting can also be used to quickly disable parts of your code when you're testing or working on a new feature that isn't ready yet. Learning how to properly use comments will lead to more efficient coding, for you and your coworkers.

1
Insert a single-line comment. Comments are designated by the tags . You can insert quick comments to remind you what is happening with the code.
```
<html>
<head>
<title>Comment test</title>
</head>
<body>

<p>This is the website</p>
</body>
</html>
```
- Make sure there are no spaces in the comment tags. For example < !-- will not activate the comment function. Inside the tags, you can have as many spaces as you'd like.
2
Create a multiline comment. Your comments can span multiple lines, which is useful for explaining complex code, or for blocking off large pieces of code.
```
<html>
<head>
<title>Comment test</title>
</head>
<body>

<p>This is the website</p>
</body>
</html>
```

Use the comment function to quickly disable code. If you're trying to track down a bug or want to keep code from running on the page, you can use the comment function to quickly block it off. That way, you can easily restore the code by deleting the comment tag.
```
<html>
<head>
<title>Comment test</title>
</head>
<body>
<p>Check out these images</p>

<img src="/images/image1.jpg">

</body>
</html>
```

Use the comment function to hide scripts on unsupported browsers. If you are programming in JavaScript or VBScript, you can use the comment function to hide the script on browsers that don't support it. Insert the comment at the start of the script, and end it with //--> to ensure that the script works on browsers that do support it.
```
<html>
<head>
<title>VBScript</title>
</head>
<body>
<script language="vbscript" type="text/vbscript">

</script>
</body>
</html>
```
- The // in the end tag will prevent the script from executing the comment function if scripts are supported by the browser.^{[1]

Question

How do you code it so people can add comments on your website about the actual thing?

Community Answer

Comments placed on your website are done in PHP & MySQL code, not HTML. If you have CPanel, you can go to your Softaculous Apps Installer and install an APP that will either create a bulletin board, guest book or even down load word press onto your site. These apps are already written PHP/MySql and you can turn off or on the comments.

HTML code can get messy quickly so you should use comments to structure your code. Add comments at the start and the end of code sections to make it easy to find.
