The DOM header object is used to represent the HTML <header> element. The header element can be accessed by the getElementById() method.
Syntax:
document.getElementById("id");
Where ‘id’ is the ID assigned to the header tag.
Example 1: In the below program the header element is accessed and the color of the text inside the header element is changed.
HTML
<!DOCTYPE html>
< html >
< body >
< h1 style = "color:green;" >
GeeksForGeeks
</ h1 >
< h2 >DOM header Object</ h2 >
< article >
< header id = "head" >
< p >A computer science portal for geeks.</ p >
</ header >
</ article >
< button onclick = "Geeks()" >Click Here!</ button >
< script >
function Geeks() {
let doc = document.getElementById("head");
doc.style.color = "green";
}
</ script >
</ body >
</ html >
|
Output:
Example 2: Header Object can be created by using the document.createElement method.
HTML

< p id = "head" style = "color:green;" ></ p >
< script >
function Geeks() {
let x = document.createElement("HEADER");
document.body.appendChild(x);
let doc = document.createElement("H3");
let t = document.createTextNode(
"A computer science portal for geeks.");
doc.appendChild(t);
document.getElementById("head").appendChild(doc);
