Today we’re releasing Bootstrap v3.1.1. As our first patch release for the v3.1.x release series, we’ve focused on CSS bug fixes, documentation improvements, and further refinements to our build tools. See the included changelog for more details.
Today we’re stoked to ship Bootstrap v3.1. We’ve got a handful of new features, plenty of bug fixes and improvements, and updated build tools.
New docs
We’ve made tons of changes across the board, most notably to our documentation. Just like v2.1 brought a brand new design, v3.1 overhauls the docs to refocus on the actual documentation rather than the chrome around it. Our new homepage restores the quick run through of key features and showcases some awesome examples from the Expo.
Official Sass port
The best part about v3.1 is that we’re shipping with an official Sass port. A few weeks ago we moved over the most popular port on GitHub and made it official—Bootstrap is now available in Sass. Rather than bloat the main project with support for Less and Sass—and all the documentation for both—we’ve kept them separate for the time being. Prominent links in the docs are included though, so enjoy!
New examples
We’ve added three new examples: Blog, Cover, and Dashboard. Each example provides a single page of awesomeness for you to quickly get started on a project built with Bootstrap. They’re responsive and ready to go.
Improved features
A handful of features that aren’t exactly new to Bootstrap have seen an update in v3.1:
Modals now include optional sizes
Dropdowns now have their own alignment classes for easier customization
Form feedback styles for validation states now include optional icons to reinforce color changes
All-in-all these make components more focused, more durable, and easier to work with. See the changelog included with the GitHub release for the complete list of new features.
Remote modal content
One of the more important improved features is for our modals. If you currently use the modal’s remote option, be aware this release may break your modals. Yes, this is a breaking change, but it’s first and foremost a bug fix that corrects a rather longstanding and overlooked error. Our apologies for any headaches it may cause, but it’s been missed in the last few patch releases.
See the #11933 pull request for details on the code changes.
New license
We’ve been talking about it for what seems like forever, but thanks to all our contributors and the core team, we’ve finally done it. As of v3.1, Bootstrap ships under the MIT license to allow as many people to utilize Bootstrap as possible. Thanks to all our contributors for helping make it happen.
Improved build tools
We’re constantly trying to improve our tools for developing Bootstrap and v3.1 brings a slew of updates to do just that.
We’ve switched from Recess to grunt-contrib-less for our compiler, giving us access to Less 1.6.x (as opposed to 1.3.x with Recess).
Our compiled code is virtually identical in formatting and organization thanks to CSScomb and some other Grunt-fu.
Tests also run a tad faster with the help of some magical caching and parallelization.
The web Customizer is now generated from a Grunt task, meaning we’ll never miss updating or adding a variable again. If you contribute to Bootstrap regularly, just run grunt and commit to update the page.
Heads up! If you develop Bootstrap locally, be sure to nuke your node_modules/ directory and run npm install before getting started with v3.1.
Download Bootstrap
Get downloading now, or see the list below for more information on what’s new in this release. Download it from GitHub or snag it from the CDN:
#11572: Add contextual background-color classes to match our existing text classes. (This also moves both sets of classes to the Helper Classes section of the CSS docs.)
#11675: Add .text-justify class to round out the text alignment classes.
#11836: Add new form control feedback classes to toggle icons for each validation state. Works on regular forms, horizontal, and inline.
While we originally wanted v3.1 to include RTL support, we decided to hold back on that for some potentially beneficial unreleased tooling. We’ll share more on that when we know more, but suffice to say it’s been bumped to v3.2.
CSS changes
#10951: Add outline: 0 to .modal to prevent a focus outline from appearing in Chrome for Windows.
#11107: Add @modal-backdrop-opacity variable for customizable modal backdrop.
#11266: Apply a pixel-based line-height that matches the height to date inputs for iOS 7 for proper vertical alignment of text in the form control.
#11302: Refactor the responsive utility classes to cut a few hundred lines of CSS (more context in #11214).
#11435: Prevent the double borders between multiple buttons in an input group.
#11561: Add float: left; to .form-controls within input groups to prevent IE9 from screwing up placeholder text and select menu arrows.
#11588: Scope font-size to only <p> elements in .jumbotrons and remove the super-sized line-height from the base class to avoid interference with sub-components.
#11676: Add -webkit-overflow-scrolling: touch; to modals for smooth scrolling on iOS devices.
#11744: Clean up some incompatible properties in forms.less: block level inputs no longer receive vertical-align: middle; unless necessary, e.g. in inline forms.
#11748: Updated .scale() mixin so that it accepts optional vertical scale as second parameter.
#11750: Reverts v3.0.3’s refactor to contextual table classes to ensure they work with striped tables.
#11757: Darken default navbar toggle bars to meet WCAG criteria.
#11766: Use @color variable in .button-variant() mixin to set background-color on .badges in buttons for proper default button badge styles.
#11741: Don’t set @headings-font-family to the same font stack as the <body>; instead, just use inherit for same default CSS.
#11786: Nest media queries within print utilities for mixin-friendliness.
#11790: With upgrade to Less v1.6.0, remove duplicate CSS generated from the nested .clearfix class and mixin by switching to &:extend(.clearfix all).
#11801: Use correct variables for grid containers.
#11817: Rework input groups to use the font-size: 0; and white-space: nowrap hack for a more durable component with regards to code formatting and custom font size changes.
#11829: Add .make-xs-column mixins to complement the recently added extra small predefined grid classes.
#11836: Along with the form validation update, we reset some key form and icon styles:
All .form-controls within inline forms are set to width: auto; to prevent stacking of .form-label within a .form-group.
Removes all select.form-control settings since those are now inherited by the above change
Removes the width: 1em; from the Glyphicons because it was virtually impossible to override.
#11841: Breadcrumb padding values now use variables.
#11859: Restore @dropdown-caret-color variable, but deprecate it.
#11861: Add @list-group-active-text-color variable for improved customization on active list group items.
#11868: Cleanup modal z-index values in modals.less.
#11990, #12159: Make range inputs block level and 100% wide by default.
#12073: Make order of component variations consistent throughout the repo.
#12164: Fix value of SVG font ID and removed hard coded value.
#12171: Ensure panel groups have a bottom margin since we nuke it on child panels.
#12247: Add and use .text-emphasis-variant() mixin for emphasis classes. Also updated emphasis classes to only apply :hover styles to linked content.
#12248: Add and use .bg-variant() mixin to generate background classes.
#12249: Add and use @modal-md Less variable for uniformity.
#12250: Remove print margins per upstream H5BP change, thus deferring to browser defaults, or users’ custom values should they set them.
#12286: Only remove appropriate border-radius from first and last tables or list groups in panels.
#12353: Scope table border reset in panels to first-child rows.
#12359: Reset min-width on <fieldset>s so they don’t break responsive tables and behave more like standard block level elements.
#12270: Add namespace .bs also to the event dismiss.modal.
Deprecations
#10370: Deprecated the .pull-right method for aligning dropdown menus. Includes the following changes:
Removed an old and unused pair of selectors that didn’t properly target the right-aligned navbar alignment of dropdown menus.
Deprecates the .pull-right alignment in favor of a more specific and unique class name.
Adds .dropdown-menu-right as the new alignment class. This is then mixin-ed into the .navbar-right.navbar-nav dropdown menus for auto-alignment (keeping the current behavior we have today).
Adds new ability to override that auto-alignment though with the new .dropdown-menu-left, which is mixin-ed in the same way to provide the appropriate specificity of an override. This should never need to be used except for within right-aligned .navbar-nav components.
#11660: Deprecate small and .small in blockquote citation in favor of footer element.
#12037: Move docs .html pages and assets into docs/ subfolder to clean up project root directory. Also moves .csscomb.json and .csslintrc to less/ to further clean up project root.
#12073: Make order of component variations consistent throughout the repo.
#12244: Move v2.x to v3.x migration docs to a separate page.
#12311: Expand information on how to handle overflowing content in navbars.
#12314: Add warning about modal markup placement affecting modal appearance/functionality.
#12345: Add note about printer viewport weirdness.
There are a few dozen bug fixes and changes in this release, but we’ve called out the ones we think matter most:
Padding of .navbar-collapse and alignment of .navbar-right:last-child elements has been reworked.
Added a max-width: 100%; to .containers.
Restored the twelfth column’s float: left; at all grid tiers.
See the list below for more information on those changes and more.

Next up is v3.1.0, the first new feature release for Bootstrap 3. Stay tuned for more information on what’ll be in that release as we continue to plan out subsequent releases.
Today we’re shipping a quick v3.0.2 patch to fix incorrect version numbers in our JavaScript files, restore missing grid classes, and make a few improvements to our documentation.
#11334: Remove unnecessary & from CSS nesting for panels.
#11335: Add Grunt task to update version numbers across entire project. (Note: If you run our docs locally, you’ll need to run npm install in order to run grunt).
#11336: Don’t use nonstandard window.location.origin in Customizer.
#11345: Remove duplicate class changes in migration instructions.
#11349: Add screen reader text for navbar toggles.
#11378: Use .navbar-* alignment classes in .navbar-text example.
This release was unplanned, and as such it bumps a lot of planned fixes to a v3.0.3 release. We’ve already updated the relevant issues to be under the new v3.0.3 milestone. Look for that release, and perhaps another patch, before v3.1.0 ships in the coming months.
Today we’re shipping v3.0.1, a huge patch release with over 750 commits since v3 was released two months ago. We’ve outlined most of the changes below, including documentation updates, bug fixes, and even a few deprecations (our first in the history of the project).
Remove links to navbar examples from example navbars in Theme example
Delete smaller touch icons and only include one
Remove unused mention of .prettyprint styles from code.less (we no longer use that plugin and the class is undocumented, so we’re nuking it)
Remove unnecessary left and right properties from .modal-dialog since we use margin to center the modal
Add Linux Firefox to supported browsers list
Update outdated JSFiddle example
Bug fixes and changes
#9855: Partial fix for open modal content shifting: removed all margin settings to prevent some of the content shifting. Still needs JS love to detect scrollbars and adjust content accordingly (will address in v3.0.2).
#9877: Add improved .active state to navbar nav in theme
#9879: Add hover state (move gradient up 15px) to theme buttons]
#9909: Add @component-active-color variable to complement @component-active-bg (and apply it to dropdowns, nav pills, and list group items)
#9964: Add fonts directory to bower.json main files list
#9968: Simplify striped progress bar mixin to remove unused color
#9969: Add support for output element by styling it more like our .form-control
#9981: Account for hover and focus states on pagination disabled items

#10013: Position carousel left and right controls from the left and right, respectively
#10014, #10406: Update grid to use width on .containers instead of max-width as IE8 doesn’t fully support box-sizing: border-box when combined with min/max width/height
#10022: Add width: 1em; to all empty Glyphicons to prevent loading flicker
#10024: Use negative margin to fix the border between button and input in input groups
#10601: Use overflow-y: auto; for .navbar-collapse instead of visible to better enable scrolling on Android 4.x devices (see issue for more details on support and gotchas)
#10620: Remove filter on buttons for IE9 in theme.less due to bleed-through with rounded corners (matches behavior and style of Bootstrap 2.x)
#10641: Remove unused .accordion-toggle class from docs example
#10656: Inherit link and caret colors for textual dropdowns in panel headers
#10694: Remove unnecessary content property from .caret
#10695: Ensure carets in .nav-pills dropdown links inherit active color
#10729: Removed the unnecessary override and the !important from .wrap in the sticky footer examples
#10755: Don’t remove quotes around q element by default
#10778: Use newly-updated Glyphicons to workaround old Android WebKit bug

#11127: .navbar-fixed-bottom should have a top border, not a bottom border
#11139: Add position: relative; to .modal-dialog so that the z-index takes effect
#11151: Remove rogue H5BP .ir class from print styles
#11186: Add background-color hacks so that clicking carousel indicators in IE8-9 works as intended
#11188: Refactor z-index on navbars. Removes the default z-index: 1000; and instead only applies it to static-top, fixed-top, and fixed-bottom. Also fixes up the broken default navbar example’s fubared padding.
#11206: Remove padding-left from first list item within .list-inline
#11244: Adds .animation() mixin to replace .progress-bar’s regular CSS animation properties (and drops the -moz, -ms, and -o prefixes as they are not needed per https://caniuse.com/#feat=css-animation).
#11248: Apply background-color: #fff; to selects in print styles to fix Chrome bug
Audited Customizer variables section and rearranged content
Deprecated
#9963, #10567: Deprecate @screen-* variables for @screen-*-min to better match the @screen-*-max variables and provide more context to their actual uses.
#10005: Finish removing uses of @screen-{device} variables by deprecating them for @screen-*-min wherever possible.
#10100: Deprecate .hide-text mixin for .text-hide. This matches our class-mixin strategy elsewhere (e.g., .clearfix) and ensures the class and mixin use the same name to avoid confusion.
#10125: Deprecate inconsistent container variables for new @container-{screen-size} variables (e.g., use @container-sm instead of @container-tablet)
#10769: Deprecate .hide for .hidden so we don’t duplicate functionality.
We’ve been looking to move to the MIT license for quite some time, and today’s release takes us that much closer. Starting with v3.0.1, all new contributions to Bootstrap will be dual-licensed as Apache 2 and MIT. The intent is to move the entire project (including all prior contributions) to the MIT license in a future version (hopefully v3.1.0).
To make the change, every contributor to Bootstrap must consent to relicense their changes (since we have no CLA). We’re making excellent progress on that front with the community’s help and will address holdouts as they come up.
As a heads up, we’ve placed notices in the contributing guidelines and our project readme about the pending change and transition period.
It goes without saying that we don’t need to do this, but we want to make Bootstrap available to all communities who cannot currently use it due to licensing conflicts. Theoretically these communities could change their licenses, but when you step back and objectively look at the situation, it’s much easier for us to change. We hope you understand and stick it out with us as we make the move.
Growing the team
The Bootstrap core team doubled a few months ago when we added Chris and Julian to the project. They’ve helped manage issues, written some awesome code, and provided critical input in the direction of the project. As Bootstrap grows, so too must our core team, and we’re once again actively seeking new team members.
It’ll be a slow process, much like last time, but we need the help on several fronts to keep us shipping and iterating. In particular, we’ll be keeping an eye out for folks with top notch CSS and JavaScript skills.
Up next
We’re already tracking issues for a v3.0.2 release and its changes will be along the same lines as today’s release—bugs and docs. v3.1.0 will likely ship after that sometime with a few new features. As always, no dates have been set yet for any future releases.
