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
        </title>
    </head>
      
    <body style = "text-align:center;"
  
        <h1 style = "color:green;"
            GeeksForGeeks 
        </h1
          
        <h2>DOM strong Object</h2
          
        <!-- Assigne 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"; 
            
        </script
    </body
</html>                    

Output:
Before click on the button:
strong
After click on the button:
strong



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




<!DOCTYPE html> 
<html
    <head>
        <title>
            HTML DOM Strong Object
        </title>
    </head>
      
    <body style = "text-align:center;"

        </h1
          
        <h2>DOM strong Object</h2
          
        <button onclick = "myGeeks()">
            Submit
        </button><br>
          
        <!-- script to display strong element -->
        <script
            function myGeeks() { 
                var elem = document.createElement("STRONG"); 
                var txt = 
                document.createTextNode("GeeksForGeeks:" 
                +"A computer science portal for geeks."); 
  
                elem.appendChild(txt); 
  
                document.body.appendChild(elem);
