    <body style = "text-align:center;">
 
        <h1 style = "color:green;">

        </h1>
         
        <h2>DOM strong Object</h2>

            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";
