Zebra striped list

Creates a striped list with alternating background colors, which is useful for differentiating siblings that have content spread across a wide row.

HTML

<ul>
  <li>Item 01</li>
  <li>Item 02</li>
  <li>Item 03</li>
  <li>Item 04</li>
  <li>Item 05</li>
</ul>

CSS

li:nth-child(odd) {
  background-color: #eee;
}

Demo

Explanation

1. Use the :nth-child(odd) or :nth-child(even) pseudo-class to apply a different background color to elements that match based on their position in a group of siblings.

Note that you can use it to apply different styles to other HTML elements like div, tr, p, ol, etc.

Browser support

✅ No caveats.
