The Concise CSS framework is a completely free open source lightweight option for frontend developers. It’s written in Sass for the modern developer who can’t part from his/her favorite preprocessor.
If you visit the actual landing page you’ll realize the site is just as lightweight as the library.
Everything is bloat-free with a focus on ease of use. There are plenty of add-ons with the ability to code your own, too.
Anyone new to Concise who may wnat to learn should check out the free documentation. It relies on Sanitize.css with its own series of custom resets based solely on Concise’s portability.
Concise.css is also available for free download on GitHub with a few example code snippets for setup. Feel free to download a copy and try it out in your next project.
Also you can stay up-to-date with Concise CSS on Facebook or via Twitter @ConciseCSS.
