Can CSS3 be used to style the children divs of a parent div with specific conditions, such as:
Is jQuery necessary for implementing this dynamic logic or can it be achieved with CSS alone?
.parent div {
height: 1em;
width: 1em;
background: red;
margin: 0.5em;
}
.parent div:last-child {
background: green;
}<div class="parent">
<div></div>
<div></div>
<div></div>
</div>
<hr />
<div class="parent">
<div></div>
<div></div>
</div>
<hr />
<div class="parent">
<div></div>
</div>I believe that the issue can be resolved using only CSS.
Consider using the last-child selector: http://www.w3schools.com/cssref/sel_last-child.asp
Apply the same style to all child elements and then adjust the style for the last child element.
This way, in a scenario with 3 divs, the style will apply to the third div as the last child, and in a scenario with 2 divs, it will apply to the second child as the last one, and so on.
Unfortunately, achieving this with just CSS is not possible. However, a simple jQuery solution involves adding a specific class to the parent div based on the number of children it contains (e.g., 'has-3-children').
var targetDiv = $('.target-div-class');
targetDiv.addClass('has-' + targetDiv.find('.child-div-class').length + '-children');
You can then easily style elements based on this added class.
