The look and feel of applications is very important. It can make or break the usability of an application. Joomla and other website have a nice way of showing content on different sort of devices.
C3 baseview
Over the last couple of years BizzXL developed C3_Baseview: an easy way to faster create Joomla views based on a Library. It is designed to extend (page) views of the Joomla Framework. Baseview standardizes the views you use most. As Joomla Bootstrap was not up to our requirement we choose UiKit Opensource. This means that using a Yootheme template will give you all the benefits for pixel perfect styling.
At this moment of writing (dec 2015) the Joomla community is still not sure what the way is to go, we have decided to not develop till the structure is clear. In the near future a version of Baseview might be available on Github including a support for multiple Style Libraries.
