HTML | DOM Style backgroundPosition Property
The HTML DOM Style backgroundPosition : It sets or returns position of the background-image in an element.
Syntax:
- To get the backgroundPosition property
object.style.backgroundPosition
- To set the backgroundPosition property
object.style.backgroundPosition = value
Property Values:
- keyword values: this is used to specify the position using keywords. If only one value is specified, the other value would be ‘center’ by default. The possible keyword combinations are:
- top left
- top center
- top right
- center left
- center center
- center right
- bottom left
- bottom center
- bottom right
- x% y%: this is used to specify the position using percentage. The x% determines the horizontal position and y% determines the vertical position with respect to the initial top-left position.
- xpos ypos: this is used to specify the position using a pixels or any other CSS measurement. The xpos determines the horizontal position and ypos determines the vertical position with respect to the initial top-left position.
- initial: this is used to set this property to its default value.
- inherit: this inherits the property from its parent.
The values are explained using the following examples:
Example-1: Using keyword values. We use the value ‘bottom right’ in this example.
<!DOCTYPE html><html lang="en"> <head> <title> DOM Style backgroundPosition Property </title> <style> .bg-img { height: 300px; width: 300px; border-style: solid; background: no-repeat center; } </style></head> <body> <h1 style="color: green"> GeeksforGeeks </h1> <b> DOM Style backgroundPosition Property </b> <p> Click on the button to change the position of the background image </p> <div class="bg-img"> </div> <button onclick="changePos()"> Change position of background image </button> <script> function changePos() { elem = document.querySelector('.bg-img'); // Setting the position to bottom vertically // and right horizontally elem.style.backgroundPosition = 'bottom right'; } </script></body> </html> |
Output:

- After pressing the button:
Example-2: Using percentage to specify the position. We use ‘25% 75%’ to position the image.
<!DOCTYPE html><html lang="en"> <head> <meta charset="UTF-8"> <title> DOM Style backgroundPosition Property </title> <style> .bg-img { height: 300px; width: 300px; border-style: solid; background: no-repeat center; } </style></head> <body> <h1 style="color: green"> GeeksforGeeks </h1> <b> DOM Style backgroundPosition Property </b> <p> Click on the button to change the position of the background image </p> <div class="bg-img"> </div> <button onclick="changePos()"> Change position of background image </button> <script> function changePos() { elem = document.querySelector('.bg-img'); // Setting the position to 25% horizontally //and 75% vertically elem.style.backgroundPosition = '25% 75%'; } </script></body> </html> |
Output:
- Before pressing the button:
- After pressing the button:
Example-3: Using fixed units to specify the position. We use ’50px 25px’ to position the image.
<!DOCTYPE html><html lang="en"> <head> <title> DOM Style backgroundPosition Property </title> <style> .bg-img { height: 300px; width: 300px; border-style: solid; background: no-repeat center; } </style></head> <body> <h1 style="color: green"> GeeksforGeeks </h1> <b> DOM Style backgroundPosition Property </b> <p> Click on the button to change the position of the background image</p> <div class="bg-img"> </div> <button onclick="changePos()"> Change position of background image </button> <script> function changePos() { elem = document.querySelector('.bg-img'); // Setting the position to 50px horizontally //and 25px horizontally elem.style.backgroundPosition = '50px 25px'; } </script></body> </html> |
Output:
- Before pressing the button:
- After pressing the button:
Example-4: Using the initial value. This sets the position to its default value.
<!DOCTYPE html><html lang="en"> <head> <title>DOM Style backgroundPosition Property</title> <style> .bg-img { height: 300px; width: 300px; border-style: solid; background: no-repeat center; } </style></head> <body> <h1 style="color: green"> GeeksforGeeks </h1> <b> DOM Style backgroundPosition Property </b> <p> Click on the button to change the position of the background image </p> <div class="bg-img"> </div> <button onclick="changePos()"> Change position of background image </button> <script> function changePos() { elem = document.querySelector('.bg-img'); // Setting the position to the default // value with initial elem.style.backgroundPosition = 'initial'; } </script></body> </html> |
Output:
- Before pressing the button:
- After pressing the button:
Example-5: Using the inherit value. This inherits the position from its parent element.
<!DOCTYPE html><html lang="en"> <head> <title> DOM Style backgroundPosition Property </title> <style> /* Parent element */ #parent { height: 300px; width: 300px; border-style: solid; /* Setting the parent's background-position //to center left*/ background-position: center left; } .bg-img { height: 300px; width: 300px; background: no-repeat center; } </style></head> <body> <h1 style="color: green"> GeeksforGeeks </h1> <b> DOM Style backgroundPosition Property </b> <p> Click on the button to change the position of the background image </p> <div id="parent"> <div class="bg-img"></div> </div> <button onclick="changePos()"> Change position of background image </button> <script> function changePos() { elem = document.querySelector('.bg-img'); // Setting the position to inherit from its parent elem.style.backgroundPosition = 'inherit'; } </script></body> </html> |
