HTML | DOM Section Object

The Section Object in HTML DOM is used to represent the HTML <section> element. The section element can be accessed by using getElementById() method.

Syntax:

document.getElementById("id")

Where id is assigned to the <section> tag.

Example 1:

<!DOCTYPE html>  
<html>  
    <head> 
        <title> 
            HTML DOM section Object 
        </title> 
    </head> 
      
    <body style = "text-align:center;">  
  
        <h1 style = "color:green;" >  
            GeeksForGeeks  
        </h1>  
          
        <h2>DOM section Object</h2>  
          
        <button onclick = "Geeks()"> 
            Click Here 
        </button> 
          
        <br><br> 
  
        <section id = "sec"> 
            A computer science portal for geeks. 
        </section> 
          
        <script> 
            function Geeks() { 
                var txt = document.getElementById("sec"); 
                txt.style.color = "green"; 
            } 
        </script> 
    </body>  
</html>                     

Output:

                document.body.appendChild(x); 
                  
                var para = document.createElement("H5"); 
                var txt = document.createTextNode("This"
