Zenario offers you a quick method to add CSS classes to both a page and a layout. Simply follow these guidelines.
To add your own CSS class to a content item follow these steps.
Under the "Edit" tab of your page go to "Properties" and then click on "Edit metadata"
A floating admin box will appear.
Click on the "Background & CSS" tab and at the bottom is a field to add your own class name.
If you want to add a CSS class to a layout a very similar method is used.
Go to the "Layout" tab on the front-end and click on "Change skin".
A floating admin box will appear.
Again go to the "Background & CSS" tab.
At the bottom of the box there is a field to your classes.
You can now add CSS classes to content items and layouts.
