Comments are not displayed on the web-browser and have no any visual effect on the web pages.
Generally, comment sections are green color in the editor.

The following example is wrong of using HTML comment.

<!DOCTYPE html>
<html>
<head>
</head>
<body>

<!--start first para
  <p> First para </p>

  <p> Second para </p>
end second para-->

</body>
</html>

It will not display anything on the web browser. HTML comment must strictly obey the basic syntax of defining it.
