Hello, I'm interested in having 5 different backgrounds for users to choose from. I want them to be able to click on a thumbnail and have the site's background change dynamically. Could you please advise me on how to achieve this? Thank you for any assistance.
Understanding the basics of html and javascript is essential before attempting this task. To begin, you need to create an html structure similar to the following:
<div class="container" data-image="image1.jpg"></div>
<div class="container" data-image="image2.jpg"></div>
<div class="container" data-image="image3.jpg"></div>
<div class="container" data-image="image4.jpg"></div>
<div class="container" data-image="image5.jpg"></div>
A sample CSS code to style these containers:
.container {
width: 50px;
height: 50px;
border: 1px solid black;
background-color: blue;
}
The necessary javascript code:
var elements = document.getElementsByClassName("container"); // retrieve all elements
for(var i in elements) { // iterate through them
elements[i].click(function(e) { // handle click event
document.getElementsByTagName("body")[0].style.backgroundImage = this.dataset().image; // update background image
});
}
