How can I use JavaScript to dynamically change the background color of my webpage?

Customizing Webpage Aesthetics: Changing Background Color with JavaScript

Manipulating the visual appearance of webpages is an essential aspect of web design. One common adjustment is changing the background color. JavaScript offers a straightforward solution to achieve this.

JavaScript Method for Background Color Modification

To modify the background color of a webpage using JavaScript, utilize the document.body.style.background property. Set the value of this property to the desired color to change the background.

Example Implementation

The following code demonstrates how to implement background color modification using JavaScript:

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

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

In this example, the changeBackground function accepts a color argument and assigns it to the background property. The window load event listener calls this function to set the background color to red upon page load.

Considerations

It's important to note that the effectiveness of this technique depends on the page structure. If a DIV container has its background color set differently, it may be necessary to modify its background color instead of the document body.
