Trying to perfectly center a div on a webpage using CSS can be tricky. Many common solutions found through Google tend to underestimate the complexity of the task.
Take this approach, for example:
top: 50%;
left: 50%;
This method often centers the div along with its width and height, rather than just at the precise middle point of the page. How can we achieve exact centering? Consider this scenario with a sample div:
<div class="notification-instance ui-draggable ui-draggable-handle" style="width:33.333333333333336%;position:absolute;top:50%;left:50%;margin:0 auto;">
<div class="draggable panel panel-pink">
<div class="panel-heading" style="background-color: #B00049">
Panel Title
</div>
<div class="panel-body">
Panel Body
</div>
</div>
</div>
In this situation, utilizing bootstrap's col-md classes is not an option. Furthermore, without predefined dimensions for the div due to dynamic parameters, achieving true central alignment becomes even more complex.
