Caravela now has a nice responsive theme for use on devices with smaller screens like your phone or tablet. You don’t need to do anything to activate the new theme. Just visit Caravela on your phone or tablet and you’ll automatically see a version of the site optimized for your device.
On your desktop you probably won’t notice any differences (but you can preview the mobile theme by shrinking your browser window).
Please let me know if you run into any issues or have any suggestions for improvement.
