+### Validate Item Count
+
+Thanks to [Jon Jones](http://www.jondjones.com/learn-episerver-cms/episerver-developers-guide/episerver-content-areas/how-to-add-bootstrap-row-validation-within-your-episerver-content-areas) for copyright! If you have Content Area with single row and want to validate item count inside to match single Bootstrap row (12 columns), you just need to add `[BootstrapRowValidation]` attribute:
+
+```
+public class StartPage : SitePageData
+{
+    ...
+    [BootstrapRowValidation]
+    public virtual ContentArea MainContentArea { get; set; }
+```
+
 ## Customize Bootstrap Content Area
 In order to customize available display options you need to add new ones through provider model.
