HTML Comment Tag
The HTML comment tag is represented by the <!-- and --> symbols. Any text that appears between these symbols will not be displayed on the web page, but will instead be treated as a comment by the web browser.
There are several reasons why you might want to use the HTML comment tag in your web pages. One common use is to add notes to your code that explain what certain sections do. For example, you might add a comment like <!-- This section contains the header of the page --> above the code for your header element. This can make it easier for you and others to understand and maintain your code over time.
Another use for the HTML comment tag is to temporarily remove sections of code without actually deleting them. This can be useful when you're testing different layouts or features on your web page, as it allows you to quickly switch between different versions without having to rewrite your code every time.
It's important to note that while HTML comments are not displayed on the web page, they are still visible in the source code. This means that anyone who views your web page source code can see your comments, so you should avoid including any sensitive or confidential information in them.
In addition to the <!-- and --> symbols, there are a few other things to keep in mind when using the HTML comment tag. First, comments cannot be nested within other comments. If you try to do so, the web browser will ignore everything after the first --> symbol. Second, comments should not be used to hide text from users or to manipulate search engine rankings. Doing so is considered black hat SEO and can result in your site being penalized or banned.
In conclusion, the HTML comment tag is a useful tool for adding notes and annotations to your web page source code. It can make your code more readable and easier to maintain, and it can also be used to temporarily remove sections of code for testing purposes. However, it's important to use comments responsibly and avoid including any sensitive or confidential information in them.
You can add comments to your HTML source by using the following syntax:
Notice that there is an exclamation point (!) in the start tag, but not in the end tag.
Add Comments
HTML comments are represented by the <!-- and --> symbols. Anything that appears between these symbols will be treated as a comment by the web browser and will not be displayed on the web page. You can use comments to explain what certain sections of your code do, or to add notes for yourself or other developers who may work on the code in the future.
For example, you might add a comment like <!-- This section contains the header of the page --> above the code for your header element. This can make it easier for you and others to understand the purpose of the code and how it fits into the overall structure of the web page.
Another common use for HTML comments is to temporarily remove sections of code without actually deleting them. This can be useful when testing different layouts or features on your web page. You can simply comment out a section of code and then uncomment it later when you're ready to test it again.
It's important to note that HTML comments are not displayed on the web page, but they are still visible in the source code. This means that anyone who views your web page source code can see your comments, so you should avoid including any sensitive or confidential information in them.
In addition to the <!-- and --> symbols, there are a few other things to keep in mind when using HTML comments. First, comments cannot be nested within other comments.

Doing so is considered black hat SEO and can result in your site being penalized or banned.
In conclusion, HTML comments are an essential part of web development. They provide a way to add notes and explanations to your code, which can make it easier to understand and maintain over time. However, it's important to use comments responsibly and avoid including any sensitive or confidential information in them.
With comments you can place notifications and reminders in your HTML code:
Hide Content
It is possible to hide content using comments. Comments are a way to add notes and explanations to your code that are not visible to users. By using comments to hide content, you can make it easy to temporarily remove or hide parts of your HTML without affecting the structure or layout of your web page.
To hide content using comments, simply wrap the content you want to hide with an HTML comment tag. HTML comments are represented by the <!-- and --> symbols. Anything that appears between these symbols will be treated as a comment by the web browser and will not be displayed on the web page.
Comments can be used to hide content.
For example, if you wanted to hide a paragraph of text, you could use the following HTML code:
In this example, the hidden paragraph is wrapped with an HTML comment tag, which makes it invisible to users. The visible paragraph is not wrapped with a comment tag and is therefore displayed on the web page.
It's important to note that comments should not be used to permanently hide content from users. They are intended for temporary use only, such as when you're testing a new feature or working on the design of a web page. If you want to permanently hide content from users, you should use CSS or other HTML elements to do so.
In addition, it's important to remember that comments are still visible in the source code of your web page. This means that anyone who views your web page source code can see your comments, so you should avoid including any sensitive or confidential information in them.
In conclusion, hiding content using comments is a useful technique for temporary use in HTML. By wrapping content with HTML comment tags, you can easily hide parts of your HTML without affecting the structure or layout of your web page. However, comments should not be used to permanently hide content, and you should avoid including sensitive or confidential information in them.
You can also hide more than one line. Everything between the <!-- and the --> will be hidden from the display.
Comments are also great for debugging HTML, because you can comment out HTML lines of code, one at a time, to search for errors.
Hide Inline Content
It is possible to hide inline content using comments. Inline content refers to content that appears within an HTML element, such as text or an image. By using comments to hide inline content, you can make it easy to temporarily remove or hide parts of your HTML without affecting the layout or appearance of your web page.
To hide inline content using comments, you can use a technique called "commenting out." This involves wrapping the content you want to hide with an HTML comment tag, but instead of using the standard <!-- and --> symbols, you use a special symbol combination that tells the web browser to ignore the content.
For example, if you wanted to hide a paragraph of text within a div element, you could use the following HTML code:
In this example, the paragraph of text is wrapped with a special comment tag that starts with <!--[if false]> and ends with <![endif]-->. This tells the web browser to ignore the paragraph of text, even though it appears within the div element.
It's important to note that this technique is only supported by certain web browsers, specifically Internet Explorer. Other web browsers may not support it, so you should avoid using it for important content or functionality.
In addition, it's important to remember that comments are still visible in the source code of your web page. This means that anyone who views your web page source code can see your comments, so you should avoid including any sensitive or confidential information in them.
In conclusion, hiding inline content using comments is a useful technique for temporary use in HTML.
