Alternate table row color using CSS?

I am using a table with alternate row color with this.

tr.d0 td {
  background-color: #CC9999;
  color: black;
}
tr.d1 td {
  background-color: #9999CC;
  color: black;
}

<table>
  <tr class="d0">
    <td>One</td>
    <td>one</td>
  </tr>
  <tr class="d1">
    <td>Two</td>
    <td>two</td>
  </tr>
</table>

Here I am using class for tr, but I want to use only for table. When I use class for table than this apply on tr alternative.

Can I write my HTML like this using CSS?

<table class="alternate_color">
    <tr><td>One</td><td>one</td></tr>
    <tr><td>Two</td><td>two</td></tr>
    </table>

How can I make the rows have “zebra stripes” using CSS?

You have the :nth-child() pseudo-class:

table tr:nth-child(odd) td{
    ...
}
table tr:nth-child(even) td{
    ...
}

In the early days of :nth-child() its browser support was kind of poor. That’s why setting class="odd" became such a common technique. In late 2013 I’m glad to say that IE6 and IE7 are finally dead (or sick enough to stop caring) but IE8 is still around — thankfully, it’s the only exception.
