Adding a class to every other item
Can I add a class to every odd item?
You want to add a class to every other item in Perch so you can style it using CSS.
You can use the perch:every tag to achieve this.
<li<perch:every count="2"> class="odd"</perch:every>> ... </li>
While needing to add classes for presentational purposes is becoming less of a requirement as more browsers support CSS3 selectors such as
nth-child, it is worth remembering that you could use this technique to include additional markup or anything else you want to do with alternate items.
