<div class="parent">
<div class="child" id="child-A">
<div class="child" id="child-B">
<div class="child" id="child-C">
</div>
The main concept here is that initially, child-A will be on top, hiding child-B and child-C since they will be positioned below child-A.
There will be a feature that allows toggling to adjust the width of each child element, determining which ones are visible and which ones are hidden.
var checkboxes = document.querySelectorAll( 'input[type=checkbox]' );
function toggleCheckbox(event) {
var attribute = event.target.getAttribute("data-target");
var element = document.getElementById(attribute);
if (element.style.display === "none") {
element.style.display = "block";
} else {
element.style.display = "none";
}
}
for (var i = 0; i < checkboxes.length; i++) {
checkboxes[i].addEventListener('change', toggleCheckbox, false);
}.child{
width:200px;
height:200px;
position:absolute;
}
#child-A{
background:red;
z-index:100;
}
#child-B{
background:blue;
z-index:99;
}
#child-C{
background:yellow;
z-index:98;
}
#controls{
margin-left: 210px;
}<div class="parent">
<div class="child" id="child-A"></div>
<div class="child" id="child-B"></div>
<div class="child" id="child-C"></div>
</div>
<div id="controls">
<label><input type="checkbox" data-target="child-A" checked/> Child A </label> <br>
<label><input type="checkbox" data-target="child-B" checked/> Child B </label> <br>
<label><input type="checkbox" data-target="child-C" checked/> Child C </label> <br>
</div>To reach your objective, utilize CSS properties like position and z-index. To toggle the active state, manipulate the class of the element with JavaScript. Below is a straightforward example where clicking on the black area will toggle the active state.
let i = 0;
const children = document.querySelectorAll('.child');
function toggleDiv() {
children[i].classList.remove('active');
i = (i + 1) % 3; // considering we have 3 children
children[i].classList.add('active');
}.child {
position: absolute;
height: 100px;
width: 100px;
font-size: 20px;
background: black;
color: white;
}
.child.active {
z-index: 1;
}<div class="parent" onClick="toggleDiv()">
<div class="child active" id="child-A">child-A</div>
<div class="child" id="child-B">child-B</div>
<div class="child" id="child-C">child-C</div>
