New Features

Website

I had every single file on the website and repository professionally copy-edited so that everything was grammatically correct and flowed well.

#13: Over a year ago, I started using inuitcss on freelance projects and absolutely loved it. I've always been a fan of Harry Roberts' work, so I took inspiration from his organization of code and directory structure. I also used a couple of his mixins with and without modifying them. He alerted me that I had not properly attributed his work so I went through the entire code (and in the readme) and attributed his work and others that I took inspiration from. I appreciate his being forthright with me as I would never want to step on his toes and intentionally steal his work. I respect Harry and his work, and I want to make sure he knows that.
Changed comment formatting

#9: @adamkelso had the great idea to abstract some more of the hard-coded colors in Concise into their own variables in the _defaults.scss file. This way, people will have less trouble customizing Concise for their own projects.
Added feature switches for object-specific styling for tables, forms, and navigation.
Variablized font-size and line-height for base <html> and <body> styling
Fixed spacing for feature switches in the _defaults.scss
Fixed the issue that was happening with the (column mixin with gutters)[https://github.com/ConciseCSS/concise.css/commit/6eb6a0a70a204d6ea9457cf29411f9e6c75e83a6]. Thanks to MattDiMu at CSS-Tricks for the help.
