You probably don't have a library of mobile devices at your disposal for reviewing your website. Not to worry! You can use Sitefinity to emulate what your website will look like on several popular (and not so popular) devices.
- Edit a page
- Click "More Actions"
- Choose "Preview for Smartphones & Tablets"
- Use the drop down at the top to select a device
You can also use the toggle beside the drop down to switch between portrait and landscape orientation.
BTW... yes, that is a blackberry in the picture at the top.
