How can I dynamically change the background color of a webpage using JavaScript?

Altering Webpage Background Color with JavaScript

One common task in web development involves changing the background color of a webpage dynamically. Achieving this with JavaScript offers a straightforward solution.

To modify the background color, you can manipulate the document.body.style.background property in JavaScript. This property allows you to set the desired color value.

For instance, you could create a function that takes a color parameter and sets the background color accordingly:

function changeBackground(color) {
  document.body.style.background = color;
}
Copy after login

You can then call this function when the webpage loads to set the initial background color:

window.addEventListener("load", function() {
  changeBackground('red');
});
Copy after login

In this example, the webpage's background will be set to red when the page loads.

However, note that this may vary depending on your webpage's structure. If you're using a DIV container with a separate background color, you'll need to modify that element's background property instead of the document body.
