How can the DOM structure impact the ability to manipulate elements effectively when using CSS hover events in PHP for image displays?

The DOM structure can impact the ability to manipulate elements effectively when using CSS hover events in PHP for image displays if the target element is not a direct child or sibling of the element triggering the hover event. To solve this issue, you can use event delegation by attaching the hover event to a parent element that contains both the triggering element and the target element. This way, the event will bubble up to the parent element and still be triggered when hovering over the target element. 

<div class="parent">
    <div class="trigger"></div>
    <div class="target"></div>
</div>

<script>
    $('.parent').on('mouseover', '.trigger', function() {
        $('.target').addClass('hover');
    });

    $('.parent').on('mouseout', '.trigger', function() {
        $('.target').removeClass('hover');
    });
</script>
