* Add min-width to body when printing
This should address some inconsistencies between browsers when printing. It applies a min-width to the body so that the content better resembles what your might see on your screen. I've made it a variable for easy customizing, too.
* Don't underline buttons when printing
* Add basic print styles for page and body size to create a semi-consistent print experience across browsers
With apologies, copy/paste error following on from trying to fix conflicting Hound/Travis checks for https://github.com/twbs/bootstrap/pull/20821/ slipped through before I noticed them.
* Relative URLs were output as-is, which is suboptimal or even confusing for end-users
* Ditto for fragment identifiers
* Outputting long URLs inline with prose isn't good UX
JavaScript could potentially help with this (e.g. http://alistapart.com/article/improvingprint).
However, we're not currently interested in trying to tackle the hard problem of fancy print stylesheets/views
(particularly given the level of cross-browser inconsistency when it comes to printing).
So let's just keep things simple, vanilla, and unsurprising,
which should also make it easy for others to add their own print fanciness on top of Bootstrap.
Forcing black-and-white text & backgrounds is too harsh. Printing speed isn't everything.
Users or authors can easily enable grayscale themselves if need be.
