The easiest way for JavaScript to modify html content is to use the innerHTML attribute. Let’s take a look at the syntax:

For example, if we want to modify the content of the e388a4556c0f65e1904146cc1a846bee element:
<html>
<body>
<p id="p1">Hello World!</p>
<script>
document.getElementById("p1").innerHTML = "hello kitty!";
</script>
</body>
</html> Explanation: The above HTML document contains the e388a4556c0f65e1904146cc1a846bee element with id="p1". We use HTML DOM to get the element with id="p1". JavaScript changes the content of the element (innerHTML) to "Hello Kitty! "
