While building Elements and Design sets for WPExplorers, we were looking for a CSS Framework to keep our Elements consistent and easy to manage. Current market has a lot to offer, but unfortunately those with deep integration with Bricks are way too pricey for a CSS Framework. We wanted to avoid a situation where you need to buy a lot of addons just to get started. For that, WPExplorers CSS Framework was created. It is a lightweight utility framework based on the most popular ones used in page builders (biggest shoutout Oxyninja).
It comes with utility classes for grid layouts, fluid spacing, fluid typography and many more. For full class list, visit framework page.
