- Spacing tweaks in the general mixins
- Add comments to transform mixins about IE support
- Remove `-ms-keyframes` because only IE10+ supports it, and without
prefix
- Add new mixin to generate and customize focus state as needed
- Adds variable to set default color
- Include clear disclaimer about customizing this—it's about users', so
don't go making everything bright red and expect them not to be
confused or alarmed.
Relevant issues: #2742, #4185, #7942, #8171, #8610, #9044
* Once again no longer applies to single inputs (this is a bit simpler,
but I'm open to new ideas) but the entire set of inputs, labels, and
help text within a particular element. However, the styles are not too
dependent on markup or layout, so they're super flexible.
* Simplified the markup in the validation docs examples to match latest
changes.
* Renamed `.form-state-validation` mixin to `.form-control-validation`
to match naming of prev commit.
* Update `.nav-divider` mixin to simplify to a 1px line (one value
instead of two in parametric mixin)
* Rename and consolidate dropdown caret vars
* Add vars to Customizer
This change prevents situations where specificity causes some rules to
be overridden by the ones intended for mobile.
* Added mixin `responsive-invisibility()`
* Swapped out `display: none !important;` for new mixin
- Removed mixins for generating grid classes
- Thus, we manually declare every grid class, from 1-11 (12th unit is
excluded as that's the same as no grid columns)
- No more need for `.col` base class (yay!)
- Negative indent the rows at tablets and above once again (ugh, still
working through this part)
- Add support for `.col-md` for tablet-specific grid columns
- Still need to figure out offsets, pushes, and pulls on other
devices—right now only available on desktop
* Add start and end support to the horizontal gradient as well
* Change all variables from camelCase to use-dashes
* Better comments in the gradients mixins area
* Update current uses of gradients in dropdowns and carousel to specify only two values by direct assignment of variables
