Having the radius on the first standard alert box without showing it in the code listing could be confusing for new users, especially since the second alert box doesn't have the radius.
<div data-alert class="alert-box radius">
- This is a standard alert (div.alert-box).
+ This is a standard alert (div.alert-box.radius).
<a href="" class="close">×</a>
</div>
<div data-alert class="alert-box secondary">
This is a secondary alert (div.alert-box.secondary).
<a href="" class="close">×</a>
-</div>
\ No newline at end of file
+</div>
