* Clean up _flex.scss a little
This commit just cleans up the formating of _flex.scss by changing
it so that it uses a single `@include media-breakpoint-up` instead
of multiple. It also aligns all of the CSS properties so it looks
a bit nicer.
* Remove `-xs` from flex classes
* fix form-inline with flex enabled
* grunt
* fix alignment of labels
* shorter if syntax
* add new form example to docs for now
* update inline form docs usage guidelines
* responsive margins
* better margin utils
* fix sizing of .form-check
* flexbox alignment of .form-check
* no need to change direction
* support custom controls in inline form, for default and flex modes
* add example of custom select and checks to docs
* remove hidden and visible label variants since we cover that in the usage guidelines at the start and include hidden labels everywhere
* use property value instead of layout name
* apply to all labels
* add a visible label, space it out
* add id
* Add some flexbox nav components
- Includes .nav-justified for inline, tab, and pill nav components
- Includes example of using the flex utils (.d- and .flex-items-) for centered nav
* redo heading hierarchy a bit
* Darken dismiss icon opacity
* Darken text on active list group items
* Darken light gray for accessibility/contrast, then update gray and dark gray to match
The new breakpiont-limited class pattern is to omit the breakpoint size when using the lowest size eg. col-xs-12 to col-12. This commit implements this pattern to the grid system.
* Explore responsive display utils, but with a twist: lowest breakpoint has no breakpoint modifier in the class name
* make floats use the same format, add float-none mixin
* make spacer utils responsive by grid tier
* update scale to add two levels, document them
* change responsive spacing utils to avoid the xs abbreviation in the class name for that tier
* update code snippet to match source
* update usage in our docs
* linter
* docs updates
Firefox requires a width and flex-basis value to size the input field correctly. Despite the width being 1%, the input will size correctly at all parent widths.
