The Strong Object in HTML DOM is used to represent the HTML <strong> element. This tag is used to show the importance of the text. The strong element can be accessed by using getElementById() method.

Syntax:  

document.getElementById("id")

Where id is assigned to the <strong> tag.

Example 1:

<!DOCTYPE html>
<html>
 
<head>
    <title>
        HTML DOM Strong Object

</head>
 
<body style="text-align:center;">
    <h1 style="color:green;">
        GeeksForGeeks
    </h1>
    <h2>DOM strong Object</h2>
 
    <!-- Assign id to STRONG tag-->
    <p>
        <strong id="GFG">
            GeeksForGeeks:
        </strong>
        A computer science portal for geeks.
    </p>
    <button onclick="myGeeks()">
        Submit
    </button>
 
    <!-- set style to the strong object -->
    <script>
        function myGeeks() {
            var para = document.getElementById("GFG");
 
            /* Change the color of strong element */
            para.style.color = "green";
