* 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
* `.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.
In place of commit #9040, fix#8844
And sizing .navbar-toggle more like .btn elem
+ change `position:absolute` to `position:relative`
+ remove `right: 10px` in favor of `float:right`
+ change to `height: 34px`
+ remove `top:` in favor of `.navbar-vertical-align` basis new height
+ change `padding:` to match `.btn` el
* Instead of 20px as @line-height-base, use 1.5
* Update typographic scale for headings to use unitless as well--required some twerking of decimals a bit and some rounding
* Introduce new @line-height-computed value, which takes base font-size and multiplies it by 1.5, for use in padding and margin on components
* Rearrange sections
* Add code snippets for text and links in navbars
* Add .navbar-link back in
* Add mention of .navbar-text, but it still needs to be re-implemented
* Update nav to reflect new order
* Add top margin, calculated by subtracting height of an input from height of a navbar, and dividing by two
* Uses the same method as .navbar-form
* To use, add .navbar-btn to any button outside a form element
* Also add section to docs detailing buttons in navbars, and add more ids for the other unlinked and unmentioned sections in the side nav
* Nuke the commented out navbar forms code that's not currently needed
* Add a few more examples to the .navbar-form docs section
* Remove (for now at least) top padding on checkbox and radios
