Updating backgroundPosition for dual background images within an HTML element using Javascript

Issue at Hand: I am currently facing a challenge with two background images positioned on the body tag; one floating left and the other right. The image on the left has a padding of 50px on the left side, while the image on the right has a padding of 50px on the right side. I am seeking a solution to dynamically change the padding for each of these images using pure Javascript (not jQuery).

Your assistance is greatly appreciated! :)

#body{
      background:url('http://www.w3schools.com/css/w3css.gif') no-repeat 50px 0px,
      url('http://www.w3schools.com/css/w3css.gif') no-repeat top right 50px;
}
javascriptcss

Answer №1

Feel free to utilize the following code snippet:

document.getElementById('body').style.backgroundPosition = '150px 0, 100px 0';

The values 150px 0 and 100px 0 correspond to the positioning of the left and right images respectively.

You can also view a live demo on JSFiddle here: http://jsfiddle.net/enve/9a32b/

Answer №2

To assign an id to the tag, use something like id="main", then

document.getElementById("main").style["margin-top"] = "20px";
document.getElementById("main").style["margin-bottom"] = "20px";
