The DOM Caption Object is used to represent the HTML <Caption> element (A caption element is used to specify the caption of a table). The Caption element is accessed by getElementById().

Properties:

It has a align Attribute which is used to set or return the alignment of the caption.

Syntax:

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

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

HTML

<!DOCTYPE html>
<html>
   
<head>
    <style>
        table,
        th,
        td {
            border: 1px solid black;
        }
    </style>
</head>
   
<body>
    <h1 style="color:green;font-size:35px;">
        GeeksForGeeks
    </h1>
    <h2>DOM Caption Object</h2>
    <table>
        <caption id="GFG">Students</caption>
        <tr>
            <th>Firstname</th>
            <th>Lastname</th>
            <th>Age</th>
        </tr>
        <tr>
            <td>Priya</td>
            <td>Sharma</td>
            <td>24</td>
        </tr>
        <tr>
            <td>Arun</td>
            <td>Singh</td>
            <td>32</td>
        </tr>
        <tr>
            <td>Sam</td>
            <td>Watson</td>
            <td>41</td>
        </tr>
    </table>
    <br>
    <button onclick="myGeeks()">Submit</button>
   
    <script>
        function myGeeks() {
            let w = document.getElementById("GFG");
            w.style.color = "green";
            w.style.fontSize = "28px";
