### RubyGems
### Global changes
- **Flexbox is enabled by default.** In general this means a move away from floats and more across our components.
-- Switched from [Less](http://lesscss.org/) to [Sass](http://sass-lang.com/) for our source CSS files.
+- Switched from [Less](http://lesscss.org/) to [Sass](https://sass-lang.com/) for our source CSS files.
- Switched from `px` to `rem` as our primary CSS unit, though pixels are still used for media queries and grid behavior as device viewports are not affected by type size.
- Global font-size increased from `14px` to `16px`.
- Revamped grid tiers to add a fifth option (addressing smaller devices at `576px` and below) and removed the `-xs` infix from those classes. Example: `.col-6.col-sm-4.col-md-3`.
* `vendor/` contains third-party testing-related code (QUnit, jQuery and Sinon).
* `visual/` contains "visual" tests which are run interactively in real browsers and require manual verification by humans.
