Now navbars have their own float utility classes, mixin-ed versions of
`.pull-left` and `.pull-right`.
* Removed chained `.navbar-nav.pull-right`
* Added `.navbar-left` and `.navbar-right` as mixins of the default
float utilities, but only above the `@grid-float-breakpoint` to match
the new navbar behavior
* Updated components docs to match the new changeas
* Added callout about component alignment here to explain the new
classes
* Now responsive by default (fits better with mobile-first approach)
* Requires `.nav-header` to group `.navbar-brand` and `.navbar-toggle`
for proper mobile display.
* Changed `.nav-collapse` to `.navbar-collapse`
* Simplified examples in docs
Instead of applying `.btn-` or `.input-` to individual elements in
button and input groups, we now have new sizing classes to keep your
markup a little leaner.
* Add `.input-group-sm` or `.input-group-lg` to your `.input-group` to
replicate `.input-sm` and `.input-lg`, respectively.
* Add `.btn-group-xs`, `.btn-group-sm`, or `.btn-group-lg` to your
`.btn-group` to replicate `.btn-xs`, `.btn-sm`, and `. btn-lg`,
respectively.
Both sets of new sizing classes simply use the existing individual
sizing classes as mixins, so customization of them is automatically
inherited when compiling.
Grid classes have been changed to account for a fourth set of classes,
meaning we now have XS, S, M, and L options. Specifically, we made the
following changes:
* Renames `.col-` to `.col-xs-`
* Adds `.col-md-` for devices 992px wide and up
* Remaps `.col-lg-` for devices 1200px wide and up
Alongside that, we've updated our media queries to better handle
advanced grid layouts:
* All column classes now kick in when they hit a `min-width`, undoing
the #9128 fix in
https://github.com/twbs/bootstrap/commit/db45a60cc86190a060f0baf0b3961cb
c690f3a65
* All column offsets, pushes, and pulls are scoped to an appropriate
range, meaning a `min-width` and `max-width` (thanks for the idea,
@eratzlaff)
We've also modified the widths of our grid containers for the small
device grid (now a max 720px instead of 728px) and large device grid
(now a max 1140px instead of 1170px) to avoid horizontal scrollbar
problems in Firefox (likely due to box-sizing, which is why we didn't
see it in 2.x).
Similarly, we've updated the responsive ultility classes to match the
new four media query approach of the grid system. That means we've:
* Added new `.visible-xs` and `.hidden-xs` classes
* Reassigns visible and hidden classes for small, medium, and large to
matching grid system media queries
* Updates docs examples to match grid system and account for fourth
utility range
-----
Fixes the following:
* #9135: fourth grid tier
* #9302: undoes previous range change for small grid system, so no need
to update any docs here
* #8755: consistent grid and responsive utilities schemas)
* #9195, #9216, and #9227: no more horizontal scrollbars
* `.navbar-brand` is no longer centered, thus removing need for
max-width and a few lines of code
* Clear floats of `.navbar-brand` in the `.nav-collapse` like we did in
2.x, thus simplifying some clearing and other things.
* Restyle the `.navbar-toggle` button to align it's bars up with the
text and flow of the document.
* Restyle the `.navbar-brand` to not use padding on left/right as to
avoid negative margin and other fuckery. This limits the ability to put
a bg color on the brand, but I think that's fine for now.
