How Can I Make the :nth-child Selector Ignore Hidden Elements?

How to Make nth-child Selector Ignore Hidden Elements

Issue:

In CSS, the :nth-child() selector counts hidden elements in its calculations. This can cause disruptions when hiding elements using display: none.

Solution:

To exclude hidden elements, we need to remove them from the DOM altogether. Here's a CSS-based solution and a jQuery-based solution:

CSS Solution:

.hidden {
    display: none !important;
}

The !important declaration overrides the display: none rule and completely removes the element from the page layout.

jQuery Solution:

$('.hidden').remove();

The remove() method physically removes the hidden elements from the DOM, ensuring they're not counted by the :nth-child() selector.

Example:

Consider the following HTML structure:

<div class="container">
  <div class="item"></div>
  <div class="item hidden"></div>
  <div class="item"></div>
</div>

Using the nth-child(2n) selector, the second item would be targeted. However, if we hide the second item using display: none, it would still be counted by the selector.

By using either the CSS or jQuery solution provided, the hidden element would no longer be considered by the nth-child() selector, resulting in the desired effect.
