Essentially an entire rewrite of the library—docs, CSS, and JavaScript. Adds optional responsive CSS for nearly all components.

Project changes

  • Docs: major updates across the board to general structure, examples, and code snippets. Also made responsive with new media queries.
  • Docs: all docs pages are now powered by Mustache templates and strings are wrapped in i18n tags for translation by the Twitter Translation Center. All changes to documentation must be done here and then compiled (similar to our CSS and LESS).
  • Repo directory structure: removed the compiled CSS from the root in favor of a large direct download link on the docs homepage. Compiled CSS is in /docs/assets/css/.
  • Docs and repo: one makefile, just type make in the Terminal and get updated docs and CSS.

Scaffolding

Grid system

  • Updated grid system, now only 12 columns instead of 16
  • Responsive approach means your projects virtually work out of the box on smartphones, tablets, and more
  • Removed unused (by default) grid columns support for 17-24 columns

Responsive (media queries)

  • Media queries added for basic support across mobile and tablet devices
  • Responsive CSS is compiled separately, as bootstrap-responsive.css

Base CSS

Typography

  • h4 elements were dropped from 16px to 14px with a default line-height of 18px
  • h5 elements were dropped from 14px to 12px
  • h6 elements were dropped from 13px to 11px
  • Right-aligned option for blockquotes if float: right;

Code

  • New graphical style for <code>
  • Google Code Prettify styles updated (based on GitHub's gists)

Tables

  • Improved support for colspan and rowspan
  • Styles now restricted to new base class, .table
  • Table classes standardized with .table- required as a prefix
  • Removed unused table color options (too much code for such little impact)
  • Dropped support for TableSorter

Buttons

  • New classes for colors and sizes, all prefixed with .btn-
  • IE9: removed gradients and added rounded corners
  • Updated active state to make styling clearer in button groups (new) and look better with custom transition
  • New mixin, .buttonBackground, to set button gradients

Forms

  • Default form style is now vertical (stacked) to use less CSS and add greater flexibility
  • Form classes standardized with .form- required as a prefix
  • New built-in form defaults for search, inline, and horizontal forms
  • More flexible horizontal form markup with classes for all styling, including new optional class for the label
  • Form states: colors updated and customizable via new LESS variables

Icons, by Glyphicons

  • New Glyphicons Halflings icon set added in sprite form, in black and white
  • Simple markup required for an icon in tons of contexts: <i class="icon-cog"></>
  • Add another class, .icon-white, for white variation of the same icon

Components

Button groups and dropdowns

  • Two brand new components in 2.0: button groups and button dropdowns
  • Dependency: button dropdowns are built on button groups, and therefore require all their styles
  • Button groups, .btn-group, can be grouped one level higher with a button toolbar, .btn-toolbar

Navigation

  • Tabs and pills now require the use of a new base class, .nav, on their <ul>
  • New nav list variation added that uses the same base class, .nav
  • Vertical tabs and pills have been added—just add .nav-stacked to the <ul>
  • Pills were restyled to be less rounded by default
  • Pills now have dropdown menu support (they share the same markup and styles as tabs)

Navbar (formerly topbar)

  • Base class changed from .topbar to .navbar
  • Now supports static position (default behavior, not fixed) and fixed to the top of viewport via .navbar-fixed-top (previously only supported fixed)
  • Added vertical dividers to top-level nav
  • Improved support for inline forms in the navbar, which now require .navbar-form to properly scope styles to only the intended forms.
  • Navbar search form now requires use of the .navbar-search class and its input the use of .search-query. To position the search form, you must use .pull-left or .pull-right.
  • Added optional responsive markup for collapsing navbar contents for smaller resolutions and devices.

Dropdown menus

  • Updated the .dropdown-menu to tighten up spacing
  • Now requires you to add a <span class="caret"></span> to show the dropdown arrow
  • The navbar (fixed topbar) has brand new dropdowns. Gone are the dark versions and in their place are the standard white ones with an additional caret at their tops for clarity of position.

Labels

  • Label colors updated to match form state colors
  • Not only do they match graphically, but they are powered by the same new variables

Thumbnails

  • Formerly .media-grid, now just .thumbnails, we've thoroughly extended this component for more uses while maintaining overall simplicity out of the box.
  • Individual thumbnails now require .thumbnail class

Alerts

  • New base class: .alert instead of .alert-message
  • Class names standardized for other options, now all starting with .alert-
  • Redesigned base alert styles to combine the deafult alerts and block-level alerts into one
  • Block level alert class changed: .alert-block instead of .block-message

Progress bars

  • New in 2.0
  • Features multiple styles via classes, including striped and animated variations via CSS3

Miscellaneous components

  • Added documentation for the well component and the close icon (used in modals and alerts)

Popovers

New plugins
