<body>
  <header class="header">

  <main class="main">
    <!-- main content here -->
  </main>
  <footer class="footer">
    <!-- footer content here -->
  </footer>
</body>

html, body {
  height: 100%;
}
body {
  display: flex;
  flex-direction: column;
}
.main {
  flex: 1;
}
.footer {
  margin-top: auto;
  display: flex;
  flex-direction: column;
  justify-content: center;
  align-items: center;
}

To achieve this, there are a few things to keep in mind:

Set the height of the html and body elements to 100% so that they take up the full height of the screen, even if the content is not long enough to fill the entire height.
Set the flex property of the .main element to 1, which means it will grow to fill any remaining space in the body element after the header and footer have been sized.
Use margin-top: auto on the .footer element to push it to the bottom of the body element and take up any remaining vertical space.

By using percentage-based height on the html and body elements, and flex property on the .main class, the layout can adapt to different screen sizes and resolutions while maintaining a consistent vertical arrangement of header, main content area, and footer. This approach is particularly useful for creating responsive web designs that work well on mobile devices, tablets, and desktops.
