Comment puis-je changer la couleur d'arrière-plan d'une page Web à l'aide de JavaScript ?

Altering the Background Color with JavaScript

Changing the background color of a webpage with JavaScript is a straightforward task. Here's how to do it:

Solution:

1. Access the document body: Utilize the document.body property.
2. Modify the background style: Set the background property of document.body.style. For instance, to set it to red, use document.body.style.background = 'red'.

Here's a sample function to achieve this:

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

Toinvoke the function, add the following code to the page's onload event handler:

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

Note:

Consider the page's structure. If the background is set to a specific DIV container, you need to modify its background color instead of the document body.
