To write HTML comments insert <--- and ! - - -> at both ends of the comment. HTML comments are known to keep HTML code organized and are ignored by the browser.

The one of the most important aspects of documentation software is written comments on the code. Comments are the lines that exist in computer programs that are ignored by interpreters and compilers and are intended to be read by humans.

Writing comments allows you to make your code more readable and indicate the content of specific parts of a program made. For example, if you are writing a long program, you can use comments to keep track of certain functions or lines of code.

In this tutorial, we’ll explore how to write comments in HTML. We’ll start by looking at why comments are used in programming. Next, we’ll look at the two main types of comments:. Single- line comments and multi-line comments

Why do developers write comments

In HTML, comments are ignored? by browsers and they are removed when the code is compiled and minified. So why do we write reviews?

Comments are written to be read by humans and to help make the code easier to understand. When you’re working on a single project, it’s easy to skip comments because you’re the only person reading your code. However, if you are working on a large project that includes complex code, you can easily lose sight of the purpose of your code.

Also, if you work in a team, other people may not understand the code you wrote. If this becomes the case, people may have to follow you to find out the purpose of a specific code or they may skip a line of code without understanding what it means and how it works.

comments provide a number of benefits for developers. First , as we have discussed, comments make your code easier to understand. If you write comments on your code, you and others who have read the code will find it easier to keep track of what is happening at certain points in the code

Second , comments allow developers to explain their reasoning behind decisions about a program . This can be useful for times when a program stops functioning and requires a bug fix, or when a developer needs a greater clarity as to the reason why a particular approach was used to solve a problem. Comments can also help speed up the development process, as it is easier for you to understand your code.

HTML Comment

Comments in HTML documents are surrounded by special arrows and are separated from the rest of the program. Comments are not displayed by the browser. Here is the syntax for a basic HTML comment tag:

When our web page is open, this code does not appear on our web page. Instead of this, the code will appear in our source code for reading.

The above example is a single line comment , which means the text will only appear on one line. This type of comment is useful if your comment will be short. However, if you intend to write a long comment, you should use a multi - line comment .

The syntax for multi-lines is the same as for single-line comments , with the only difference that the comment is on a new farm line. Here is the syntax for a multi-line comment tag:

Using HTML Comments

Now that you know how to write HTML comments, you may be wondering: when should I add comments to my coded? While there are no strict guidelines on when to use feedback, and each developer and team has their own preferences, there are a few things you should keep in mind.

Comments should generally be used:

Of course, there are other situations where you can add comments to your code, but these are the most common.

Additionally , you can also use HTML comments for commenting on HTML tag blocks. This allows you to keep a line of code in your program, but tells the browser to ignore it when the HTML web page is rendered.

Commenting code outside of your program is common when debugging, because, when debugging, you need to find the cause of a problem and implement a solution, and it can be helpful to tell a program to ignore the code without completely removing it from the program. Here is an example of using HTML comments to comment code:

is an example paragraph.

This is another example, paragraph.

--->

When our browser renders this code, the second paragraph is ignored because it is included in the comments.

HTML comments, while useful, should only be used when they add value to the program. There is no need to add comments to explain all the functions of a program or to explain the arguments in a meaningful way. Here are a few tips you should keep in mind when writing HTML comments:

Conclusion

Using Comments HTML helps make your reminder prog more readable both for you and for other people who would read your code. Writing comments in your code can make it easier for others to understand the intent behind your code.

In this tutorial, we have explored the basics of comments and how to create a comment in HTML. We also discussed why comments are useful, and we explored best practices for writing comments effectively . That said, each developer has their own style of commenting and as you write other comments you will find that you adopt your own.
