Altering the font size causes the spacing above and below the div to become unbalanced

I'm facing an issue with achieving symmetrical spacing in the div. When I increase the font size to 200% or 32px, there is a mismatch between the lower padding set at 3em and the <body> tag's margin of 3 em as it extends longer towards the bottom. Link to the screenshot

<html lang="en">

<head>
  <meta charset="UTF-8>
  <meta http-equiv="X-UA-Compatible" content="IE=edge">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Document</title>
</head>

<body style="margin-left: 5px;
margin-right: 5px;
margin-top: 3em;">
  <div style="text-align: center; padding-bottom: 3em; font-size:32px;">Lorem ipsum dolor sit amet</div>
  <div style="font-size: 55px; background-color: #000000; color: #FFFFFF;">Lorem Ipsum Dolor Sit Amet</div>
</body>

</html>

Answer №1

Since you have utilized the "em" unit, which is directly linked to font size, let me provide a quick definition for clarity: em: This unit is relative to the font size of the element (For example, 2em signifies twice the size of the current font)

Any adjustments made using the "em" unit will consequently impact the padding and margin accordingly.
