HTML Comments tags

  • Comment is a piece of code which is ignored by any web browser.
  • It is a good practice to add comments into your HTML code, especially in complex documents, to indicate sections of a document, and any other notes to anyone looking at the code.
  • Comments help you and other understand your code and increases code readabillity.
  • HTML comments are placed in between <!--..--> tags. So any content placed with-in <!--..--> tags will be treated as comment and will be complately ignored by the browser.
Example of comment :

<!DOCTYPE html>
<html>
        <head>
                <title>This is document title</title>
        </head>
        <body> 
                <!-- I am single comment -->
                <!--
                This is a multiline comment and it can span through as many as lines you like.-->
                <p>Document content goes here.....</p>
         </body>
</html>

This will produce following result without displaying the content given as a part of comments

Output :
Document content goes here.....

Multi-line comment :

You can comment multiple lines by the special beginning tag <!-- and ending tag --> placed before the first line and end of the last line as shown in the given example below.

<!DOCTYPE html>
<html>
        <head>
                <title>This is document title</title>
        </head>
        <body> 
                <!-- I am single comment -->
                <!--
