Bootstrap 2.3

Work-in-progress pull request for bug fixes and enhancements before our 3.0 release. Originally this was slated as 2.2.3, but since we added a feature, it gets the minor release.

Key changes

• Updated makefile to use local dependencies for easier dev setup.
• Added carousel indicators! Add the associated HTML and it automagically works.
• Added new justified navigation example. This was previously an unlinked and unsupported example I snuck in back in October. Officially adding it via the 2.3 release.
• Added sticky footer with fixed navbar example because folks seem to have trouble adapting the default example.
• Added container option to tooltips. The default option is still insertAfter, but now you may specify where to insert tooltips (and by extension, popovers) with the optional container parameter.
• Improved popovers now utilize max-width instead of width, have been widened from 240px to 280px, and will automatically hide the title if one has not been set via CSS :empty selector.
• Improved tooltip alignment on edges with #6713.
• Updated input groups to make them behave more like default form controls. Added display: inline-block;, increased margin-bottom, and added vertical-align: middle; to match <input> styles.
• Improved accessibility for links in all components. After merging #6441, link hover states now apply to the :focus state as well. This goes for basic <a> tags, as well as buttons, navs, dropdowns, and more.
• Added print utility classes to show and hide content between screen and print via CSS.
• Upgraded to jQuery 1.9. No changes were needed, but we did upgrade the included jQuery file to the latest release.
• Moved changelog to be within the repo instead of as a wiki page.
• Added .horizontal-three-colors() gradient mixin (with example in the CSS tests file).
• Added .text-left, .text-center, and .text-right utility classes for easy typographic alignment.
• Added @ms-viewport so IE10 can use responsive CSS when in split-screen mode.
• Tooltips now work with SVG.
• Updated to latest HTML5 shiv with a new local copy (within the repo) instead of the outdated Google Code version.
• Fixed z-index issues with navbar and carousel controls in the carousel example.
• Added support for th elements within tbody for .table-rounded.
• Removed target-dir from composer.json.
• Updated Holder.js from v1.6 to v1.9.
• Other miscellaneous CSS and docs bugfixes items.
