Is there an image overlapping another image?

Currently, I am working on developing a website for a Food Cart project in my class. One of the key features I want to incorporate is the ability for users to click on an image of a plate and have a different image representing the food appear on top of it. I am seeking advice on what type of javascript functions or else/if statements would be suitable to make this possible. If you need more specific details, feel free to ask.

Some examples of images I will be using include plate.gif, sandwich.gif, and more.

I appreciate any feedback or suggestions. Additionally, I am open to implementing a hover effect instead of a simple click or mouse press event.

Answer №1

By utilizing CSS, I have devised a simple method to display an image when clicking on a plate. You can easily modify it to activate on hover if necessary. To see the code in action, visit http://jsfiddle.net/suwz0zhg/1/

<img class="b" src="http://media.npr.org/assets/img/2013/01/10/plate_wide-4764eb8d34c625adfb8c18014a6f43eb300bf079.jpg?s=6" />
<img class="a" src="https://bridor.com/wp-content/uploads/product-images/60HABN-11.png" />

CSS

 img{
position:absolute;
width:300px;
height:250px;
}

.a{
margin-top:50px;
margin-left:80px;
width:150px;
height:150px;
z-index:-10;
transition:0s 10s;

}

.b:active ~ .a{
z-index:5;
transition:0s;
}

This code snippet allows you to toggle the visibility of an image by clicking on a plate, providing better cross-browser compatibility compared to CSS3 implementations. Simply click the plate to see the food item appear and disappear.

<html>
<head>
<title>Your Special Food Cart</title>
<style type="text/css">
.preview {
position:relative;
}
.preview .plate {
position:absolute;
top:0px;left:0px;
width:100%;
height:100%;
z-index:-1;
}
.preview .food {
position:absolute;
top:0px;
left:0px;
width:100%;
height:100%;
visibility:hidden;
z-index:1;
}
</style>
</head>
<body>
<script LANGUAGE="Javascript">
var shownfoodarray = new Array();
function showfood(nom) {
if (!shownfoodarray[nom]) {
shownfoodarray[nom] = 1;
} else {
if (shownfoodarray[nom] == 1) {
shownfoodarray[nom] = 0;
} else {
shownfoodarray[nom] = 1;
}
}
switch (shownfoodarray[nom]) {
case 0:
document.getElementsByClassName("food")[nom].style.visibility = "hidden";
break;
case 1:
document.getElementsByClassName("food")[nom].style.visibility = "visible";
break;
default:
document.getElementsByClassName("food")[nom].style.visibility = "hidden";
}
}
</script>
<div class="preview">
<a href="javascript:showfood(0);">
<div class="plate"><img src="http://media.npr.org/assets/img/2013/01/10/plate_wide-4764eb8d34c625adfb8c18014a6f43eb300bf079.jpg" width="200" height="200" alt="plate" border="0" /></div>
<div class="food"><img src="https://bridor.com/wp-content/uploads/product-images/60HABN-11.png" width="200" height="200" alt="food" border="0" /></div>
</a>
</div>
</body>
</html>

Given that this appears to be a school assignment, I will provide guidance on how to accomplish the task without directly sharing the code.

Start by selecting the images you plan to use. Ensure that all food images, except for the plate which serves as the base image, have a transparent background in PNG format. You can utilize design software such as Photoshop to achieve this.

For creating the illusion of various foods placed on the plate, familiarize yourself with CSS properties like position, z-index, and display. Resources from websites like W3schools can offer tutorials on these concepts.

To implement the click effect, begin by displaying the plate image. When clicked using JavaScript, overlay the first food image onto the plate. Subsequent clicks on the food image can then stack additional food images on top.

This guidance should set you on the right path towards completing the assignment successfully. While I could provide the code outright, it's essential to ensure fairness amongst your classmates. Best of luck!
