What is the use of comments in html ?

Answer 1

Comments are used to put notes in your code so that the ones reading your code (including you) have an easier time understanding it. You can also use them to dummy out a block of code you want to be able to put back easily for example.

Note: In HTML, the comments can be seen by clients looking at the source code, so don't put confidential info in there.

Answer 2

same as in other programming languages
for better understanding of code for the other people and also for u r self...
