HTML DOM Strong Object

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 the getElementById() method.

Syntax:  

document.getElementById("id")

Where id is assigned to the <strong> tag.

Example 1: In this example, we will use the Strong Object in HTML DOM.

HTML




<!DOCTYPE html>
<html>
<head>
    <title>
        HTML DOM Strong Object
    </title>
</head>
 
<body style="text-align:center;">
    <h1 style="color:green;">
        w3wiki
    </h1>
    <h2>DOM strong Object</h2>
 
    <!-- Assign id to STRONG tag-->
    <p>
        <strong id="GFG">
            w3wiki:
        </strong>
        A computer science portal for Beginner.
    </p>
    <button onclick="myBeginner()">
        Submit
    </button>
 
    <!-- set style to the strong object -->
    <script>
        function myBeginner() {
            var para = document.getElementById("GFG");
 
            /* Change the color of strong element */
            para.style.color = "green";
        }
    </script>
</body>
</html>


Output: 

 

Example 2: Strong Objects can be created by using the document.createElement method.

    </button><br>
    <!-- script to create strong element -->
    <script>
        function myBeginner() {
            let elem = document.createElement("STRONG");
            let txt =
                document.createTextNode("w3wiki:"
                    + "A computer science portal for Beginner.");
            elem.appendChild(txt);
            document.body.appendChild(elem);
