UIkit : Lightweight and Modular Front-end Framework

UIkit is a lightweight and modular front-end framework for developing fast and powerful web interfaces. It built by YOOtheme, for creating cross-browser and responsive layouts faster. UIkit gives you a comprehensive collection of HTML, CSS, and JS components
which is simple to use, easy to customize and extendable.

The components included cover pretty much everything: buttons, tables, tabs, forms, modals, tooltips and much more.

Feature:

• LESS
  UIkit is developed in LESS to write well-structured, extendable code which is easy to maintain.
• Components
  A collection of small, responsive components using consistent and conflict-free naming conventions.
• Customizer
  UIkit’s very basic style can be extended with themes and is easy to customize to create your own look.
• Responsive
  With the mobile-first approach UIkit provides a consistent experience from phones and tablets to desktops.
