HTML DOM DFN Object

The DOM DFN Object is used to represent the HTML <dfn> tag. The DFN element is accessed by getElementById().

Syntax:

document.getElementById("ID");

Where “id” is the ID assigned to the “dfn” tag.

Example 1: In this example, we will use DOM DFN Object.

html

<!DOCTYPE html>
<html>
<head>
    <title>DOM DFN Object</title>
</head>
<body>
    <h2>DOM DFN Object</h2>
    <p>
        <!-- Id assigned to the dfn tag. -->
        <dfn id="GFG">Geeksforgeeks
        </dfn> is a portal for geeks.
    </p>
    <button onclick="myGeeks()">Submit</button>
    <script>
        function myGeeks() {
            // accessing dfn
            let gfg = document.getElementById("GFG");
            gfg.style.color = "coral";
            gfg.style.fontSize = "20px";
        }
    </script>
</body>
</html>

Output:

Example 2: DFN Object can be created by using the document.createElement Method.
