What possible reason could there be for the empty space on the left side?

<ul style="background: blue; list-style: none; width: 40px; height: 40px; color: white">
  <li style="float: left; width: 20px; background: red">a</li>
  <li style="float: left; width: 20px; background: green; height: 40px">b</li>
</ul>

This block of HTML/CSS appears to create a ul element that is wider than expected, measuring 80px instead of 40px. I am unsure of the reason behind this discrepancy. Any suggestions or insight would be greatly appreciated! Here is a link to the corresponding fiddle for reference:

Thank you in advance for your help!

Answer №1

The reason is that the ul element typically has default padding.

To remove this padding, you must reset it to zero:

ul {
  padding: 0;
}

Answer №2

The reason for this behavior is the default margin and padding applied to ul elements.

<ul style="background: blue; list-style: none; width: 40px; height: 40px; color: white;margin:0; padding:0">
  <li style="float: left; width: 20px; background: red">a</li>
  <li style="float: left; width: 20px; background: green; height: 40px">b</li>
</ul>
