[html] How to keep footer at bottom of screen

Perhaps the easiest is to use position: absolute to fix to the bottom, then a suitable margin/padding to make sure that the other text doesn't spill over the top of it.

css:

<style>
  body {
    margin: 0 0 20px;
  }
  .footer {
    position: absolute;
    bottom: 0;
    height: 20px;
    background: #f0f0f0;
    width: 100%;
  }
</style>

Here is the html main content.

<div class="footer"> Here is the footer. </div>
