How to Set Padding or Margin as Percentage of Parent Container Height
When attempting to align an element vertically using CSS, it may seem logical to set the padding-top or margin-top property as a percentage of the parent container's height. However, using percentages with padding-top and margin-top results in values relative to the container's width, causing unexpected behavior when the container's width changes.
The Solution
To set padding or margin as a percentage of the parent container's height, avoid using padding-top and margin-top. Instead, set the top or bottom property of the element within the parent container.

<div>
<div>
Explanation
