History
Originally created by a designer and a developer at Twitter, Bootstrap has become one of the most popular front-end frameworks and open source projects in the world.
Bootstrap was created at Twitter in mid-2010 by @mdo and @fat. Prior to being an open-sourced framework, Bootstrap was known as Twitter Blueprint. A few months into development, Twitter held its first Hack Week and the project exploded as developers of all skill levels jumped in without any external guidance. It served as the style guide for internal tools development at the company for over a year before its public release, and continues to do so today.
Originally released on Friday, August 19, 2011, we've since had over twenty releases, including two major rewrites with v2 and v3. With Bootstrap 2, we added responsive functionality to the entire framework as an optional stylesheet. Building on that with Bootstrap 3, we rewrote the library once more to make it responsive by default with a mobile first approach.
Team
Bootstrap is maintained by the founding team and a small group of invaluable core contributors, with the massive support and involvement of our community.
Get involved with Bootstrap development by opening an issue or submitting a pull request. Read our contributing guidelines for information on how we develop.
The official Sass port of Bootstrap was created and is maintained by this team. It became part of Bootstrap's organization with v3.1.0. Read the Sass contributing guidelines for information on how the Sass port is developed.
Brand guidelines
Have a need for Bootstrap's brand resources? Great! We have only a few guidelines we follow, and in turn ask you to follow as well. These guidelines were inspired by MailChimp's Brand Assets.
Mark and logo
Use either the Bootstrap mark (a capital B) or the standard logo (just Bootstrap). It should always appear in Helvetica Neue Bold. Do not use the Twitter bird in association with Bootstrap.

A list of the browser bugs that Bootstrap is currently grappling with.
Browser bugs
Bootstrap currently works around several outstanding browser bugs in major browsers to deliver the best cross-browser experience possible. Some bugs, like those listed below, cannot be solved by us.
We publicly list browser bugs that are impacting us here, in the hopes of expediting the process of fixing them. For information on Bootstrap's browser compatibility, see our browser compatibility docs.
There are several features specified in Web standards which would allow us to make Bootstrap more robust, elegant, or performant, but aren't yet implemented in certain browsers, thus preventing us from taking advantage of them.
We publicly list these "most wanted" feature requests here, in the hopes of expediting the process of getting them implemented.

How to use
For performance reasons, all icons require a base class and individual icon class. To use, place the following code just about anywhere. Be sure to leave a space between the icon and text for proper padding.
Don't mix with other components
Icon classes cannot be directly combined with other components. They should not be used along with other classes on the same element. Instead, add a nested <span> and apply the icon classes to the <span>.
Only for use on empty elements
Icon classes should only be used on elements that contain no text content and have no child elements.
Changing the icon font location
Bootstrap assumes icon font files will be located in the ../fonts/ directory, relative to the compiled CSS files. Moving or renaming those font files means updating the CSS in one of three ways:
Change the @icon-font-path and/or @icon-font-name variables in the source Less files.
Use whatever option best suits your specific development setup.
Accessible icons
Modern versions of assistive technologies will announce CSS generated content, as well as specific Unicode characters. To avoid unintended and confusing output in screen readers (particularly when icons are used purely for decoration), we hide them with the aria-hidden="true" attribute.
If you're using an icon to convey meaning (rather than only as a decorative element), ensure that this meaning is also conveyed to assistive technologies – for instance, include additional content, visually hidden with the .sr-only class.
If you're creating controls with no other text (such as a <button> that only contains an icon), you should always provide alternative content to identify the purpose of the control, so that it will make sense to users of assistive technologies. In this case, you could add an aria-label attribute on the control itself.
Over a dozen reusable components built to provide iconography, dropdowns, input groups, navigation, alerts, and much more.

Mobile first
With Bootstrap 2, we added optional mobile friendly styles for key aspects of the framework. With Bootstrap 3, we've rewritten the project to be mobile friendly from the start. Instead of adding on optional mobile styles, they're baked right into the core. In fact, Bootstrap is mobile first. Mobile first styles can be found throughout the entire library instead of in separate files.
To ensure proper rendering and touch zooming, add the viewport meta tag to your <head>.
You can disable zooming capabilities on mobile devices by adding user-scalable=no to the viewport meta tag. This disables zooming, meaning users are only able to scroll, and results in your site feeling a bit more like a native application. Overall, we don't recommend this on every site, so use caution!
Bootstrap requires a containing element to wrap site contents and house our grid system. You may choose one of two containers to use in your projects. Note that, due to padding and more, neither container is nestable.
Use .container for a responsive fixed width container.

Bootstrap (currently v3.3.7) has a few easy ways to quickly get started, each one appealing to a different skill level and use case. Read through to see what suits your particular needs.
Bootstrap
Compiled and minified CSS, JavaScript, and fonts. No docs or original source files are included.
Bring Bootstrap's components to life with over a dozen custom jQuery plugins. Easily include them all, or one by one.
Overview
Individual or compiled
Plugins can be included individually (using Bootstrap's individual *.js files), or all at once (using bootstrap.js or the minified bootstrap.min.js).
Using the compiled JavaScript
Both bootstrap.js and bootstrap.min.js contain all plugins in a single file. Include only one.
Plugin dependencies
Some plugins and CSS components depend on other plugins. If you include plugins individually, make sure to check for these dependencies in the docs. Also note that all plugins depend on jQuery (this means jQuery must be included before the plugin files). Consult our bower.json to see which versions of jQuery are supported.
Data attributes
You can use all Bootstrap plugins purely through the markup API without writing a single line of JavaScript. This is Bootstrap's first-class API and should be your first consideration when using a plugin.
That said, in some situations it may be desirable to turn this functionality off. Therefore, we also provide the ability to disable the data attribute API by unbinding all events on the document namespaced with data-api. This looks like this:
$(document).off('.data-api')
Alternatively, to target a specific plugin, just include the plugin's name as a namespace along with the data-api namespace like this:
$(document).off('.alert.data-api')
Only one plugin per element via data attributes
Don't use data attributes from multiple plugins on the same element. For example, a button cannot both have a tooltip and toggle a modal. To accomplish this, use a wrapping element.
Programmatic API
We also believe you should be able to use all Bootstrap plugins purely through the JavaScript API. All public APIs are single, chainable methods, and return the collection acted upon.
$('.btn.danger').button('toggle').addClass('fat')
All methods should accept an optional options object, a string which targets a particular method, or nothing (which initiates a plugin with default behavior):
$('#myModal').modal()// initialized with defaults

All methods should accept an optional options object, a string which targets a particular method, or nothing (which initiates a plugin with default behavior):
$('#myModal').modal()// initialized with defaults$('#myModal').modal({keyboard:false})// initialized with no keyboard$('#myModal').modal('show')// initializes and invokes show immediately
Each plugin also exposes its raw constructor on a Constructor property: $.fn.popover.Constructor. If you'd like to get a particular plugin instance, retrieve it directly from an element: $('[rel="popover"]').data('popover').
Default settings
You can change the default settings for a plugin by modifying the plugin's Constructor.DEFAULTS object:
$.fn.modal.Constructor.DEFAULTS.keyboard=false// changes default for the modal plugin's `keyboard` option to false
No conflict
Sometimes it is necessary to use Bootstrap plugins with other UI frameworks. In these circumstances, namespace collisions can occasionally occur. If this happens, you may call .noConflict on the plugin you wish to revert the value of.
varbootstrapButton=$.fn.button.noConflict()// return $.fn.button to previously assigned value$.fn.bootstrapBtn=bootstrapButton// give $().bootstrapBtn the Bootstrap functionality
Events
Bootstrap provides custom events for most plugins' unique actions. Generally, these come in an infinitive and past participle form - where the infinitive (ex. show) is triggered at the start of an event, and its past participle form (ex. shown) is triggered on the completion of an action.
As of 3.0.0, all Bootstrap events are namespaced.
All infinitive events provide preventDefault functionality. This provides the ability to stop the execution of an action before it starts.
Guidance on how to upgrade from Bootstrap v2.x to v3.x with emphasis on major changes, what's new, and what's been removed.
Migrating from 2.x to 3.0
Bootstrap 3 is not backwards compatible with v2.x. Use this section as a general guide to upgrading from v2.x to v3.0. For a broader overview, see what's new in the v3.0 release announcement.
Major class changes
This table shows the style changes between v2.x and v3.0.
Other changes in v3.0 are not immediately apparent. Base classes, key styles, and behaviors have been adjusted for flexibility and our mobile first approach. Here's a partial list:
By default, text-based form controls now receive only minimal styling. For focus colors and rounded corners, apply the .form-control class on the element to style.
Text-based form controls with the .form-control class applied are now 100% wide by default. Wrap inputs inside <div class="col-*"></div> to control input widths.
.badge no longer has contextual (-success,-primary,etc..) classes.
.btn must also use .btn-default to get the "default" button.
.row is now fluid.
Images are no longer responsive by default. Use .img-responsive for fluid <img> size.
The icons, now .glyphicon, are now font based. Icons also require a base and icon class (e.g. .glyphicon .glyphicon-asterisk).
Modal markup has changed significantly. The .modal-header, .modal-body, and .modal-footer sections are now wrapped in .modal-content and .modal-dialog for better mobile styling and behavior. Also, you should no longer apply .hide to .modal in your markup.
As of v3.1.0, the HTML loaded by the remote modal option is now injected into the .modal-content (from v3.0.0 to v3.0.3, into the .modal) instead of into the .modal-body. This allows you to also easily vary the header and footer of the modal, not just the modal body.
The checkbox and radio features of the button.js plugin now both use data-toggle="buttons" instead of data-toggle="buttons-checkbox" or data-toggle="buttons-radio" in their markup.
JavaScript events are namespaced. For example, to handle the modal "show" event, use 'show.bs.modal'. For tabs "shown" use 'shown.bs.tab', etc.
