ProUI is a responsive and full featured Admin and Frontend Template powered by the popular Bootstrap 3.2 framework. It overwrites the default style of Bootstrap to match its own modern and clean design and at the same time extends it to a large degree without being too complicated and losing its simplicity. Even if you are not familiar with the framework, template's UI components can easily be replicated without losing focus from development.
