Main Concepts of HTML Comments
-
Purpose of Comments in HTML: Comments in HTML are lines of code that are not displayed on the web page itself, but serve as helpful annotations or explanations within the source code. They can be used for problem-solving or providing information about the code.
-
Inserting Comments in HTML: To insert a comment in HTML, you use opening
<!--
and closing-->
tags. Anything written between these tags will be treated as a comment and will not be displayed on the website. -
Visual Representation of Comments: When you add comments in HTML, they are visually represented by highlighting the text in green color in many text editors or IDEs. This makes it easy to distinguish comments from actual code.
-
Usage of Comments in Source Code: Comments are commonly used to add explanations, documentations, or reminders within the source code. They are helpful for yourself and other developers when working on unfamiliar sections of code.
-
Non-Display of Comments on Web Page: Even though comments are included in the HTML file, they are not rendered or displayed on the actual web page when it is viewed in a browser. Comments serve a behind-the-scenes function for developers rather than appearing as content on the site.
Practical Applications of HTML Comments
HTML comments are a useful tool when working on web development projects. They can help you leave notes for yourself or other developers, troubleshoot issues, and organize your code more effectively. Here's how you can add comments in HTML:
-
Identify the Section: Look for the part of your HTML code where you want to add a comment.
-
Insert the Comment Tags: Simply insert the opening
<!--
and closing-->
comment tags around the text you want to comment on. For example:<!-- This is a comment in HTML -->
-
Save the Changes: After adding your comment, save the HTML file.
-
View the HTML File: Open the HTML file in a web browser.
-
Inspect the Comments: Notice that the comments you added do not appear on the web page itself. They are only visible in the source code to provide information to developers.
Try It Out Yourself!
- Open your HTML file in a text editor.
- Find a section of code where you want to add a comment.
- Insert a comment using the
<!--
opening tag and-->
closing tag. - Save the changes and open the HTML file in a web browser to see how the comments are displayed in the source code.
By incorporating HTML comments into your projects, you can better understand your code, collaborate with others, and make the development process smoother. Start experimenting with comments in your HTML code today!
