Forten
Forten is my proprietary lightweight (S)CSS framework inpired by Milligram, with SCSS modularity, Javascript independence, B.E.M. naming schemes, and a semi-flat aesthetic.
Coming in a ~15kb size, Forten utilizes SCSS for a low cost implementation. A flexible percentage-based flexbox grid system breaks the 12-column system, while still offering familiarity. This framework embraces B.E.M. so that users can instantly identify the differences between element classes, modifying classes, and parent-dependent classes. Lastly, the framework doesn't rely on Javascript at all! Forten is still a work-in-progress.
Under The Hood
The entire framework is composed of SCSS (or Sass), aiming to abstract repetition and keeping it dry as possible. Similar to Bootstrap, Bulma, and Milligram, I used modular imports (defined by using the "_Module.scss" pneumonic). The grid/column system was inspired by Milligram, which at the time had a major leg up on Bootstrap because it used flexbox. Forten and Milligram use a percentage-based column system.
Everything else otuside of the flexbox foundation is created with an opinionated style for all elements. This was never full finished, especially because I moved my focus more on learning Javascript and eventually React.
