Employing JavaScript to overlay multiple transparent images on top of each other

I am envisioning a dynamic sandwich assembly tool where users can customize their sandwich by selecting different ingredients. By using radio buttons, I hope to visually display the sandwich taking shape as each ingredient is selected. Rather than creating numerous unique images and functions for each possible combination, I would like the ability to stack images on top of one another to create a cohesive visual representation. I have seen similar functionality in popular food ordering apps such as Pizza Hut or Domino's, where customers can build their own pizza and see the image change based on their selections. Is it feasible to achieve this concept based on my description? Thank you.

Answer №1

To achieve this, one method is to layer background images on top of each other. This can be done by incorporating the following CSS code:

.image-container{
    background:
        url(beach.png) no-repeat,
        url(sun.png) no-repeat,
        url(ocean.png) no-repeat;
}

Answer №2

For optimal rendering, I suggest utilizing a canvas element.

function render(){
    var canvas=document.getElementById("myCanvas");
    var context=canvas.getContext("2d");
    var image1=document.getElementById("1");
    context.drawImage(image1,10,10);
    var image2=document.getElementById("2");
    context.drawImage(image2,10,10);

};
$('#btn').click(function(){render();});
<button id="btn" >Render </button>

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<img id="1" width="220" height="277" src="http://www.veryicon.com/icon/png/System/Fruity%20Apples/Seablue%20512.png"  style="display:none;" />
    <img src="https://www.wildcardcorp.com/images/company-logos/mac-icon.png" id="2" style="display:none;" />

<p>Canvas:</p>
<canvas id="myCanvas" width="500" height="500" style="border:1px solid #d3d3d3;">
Your browser does not support the HTML5 canvas tag.
</canvas>
