Stack + Overflow ([`bootstrap-4`](https://stackoverflow.com/questions/tagged/bootstrap-4) tag), [Slack](https://bootstrap-slack.herokuapp.com/) or [IRC](README.md#community) are better places to get help. + +* Please **do not** derail or troll issues.

Here's what they represent and how we use them: + +- `browser bug` - Issues that are reported to us, but actually are the result of a browser-specific bug. These are diagnosed with reduced test cases and result in an issue opened on that browser's own bug tracker. +- `confirmed` - Issues that have been confirmed with a reduced test case and identify a bug in Bootstrap. +- `css` - Issues stemming from our compiled CSS or source Sass files. +- `docs` - Issues for improving or updating our documentation. +- `examples` - Issues involving the example templates included in our docs. +- `feature` - Issues asking for a new feature to be added, or an existing one to be extended or modified. New features require a minor version bump (e.g., `v3.0.0` to `v3.1.0`). +- `build` - Issues with our build system, which is used to run all our tests, concatenate and compile source files, and more. +- `help wanted` - Issues we need or would love help from the community to resolve. +- `js` - Issues stemming from our compiled or source JavaScript files. +- `meta` - Issues with the project itself or our GitHub repository. + +For a complete look at our labels, see the [project labels page](https://github.com/twbs/bootstrap/labels). + + +## Bug reports + +A bug is a _demonstrable problem_ that is caused by the code in the repository. +Good bug reports are extremely helpful, so thanks! + +Guidelines for bug reports: + +0. **Validate and lint your code** — [validate your HTML](https://html5.validator.nu/) + and [lint your HTML](https://github.com/twbs/bootlint) to ensure your + problem isn't caused by a simple error in your own code. + +1. **Use the GitHub issue search** — check if the issue has already been + reported. + +2. **Check if the issue has been fixed** — try to reproduce it using the + latest `master` or development branch in the repository. + +3. **Isolate the problem** — ideally create a [reduced test + case](https://css-tricks.com/reduced-test-cases/) and a live example. + [This JS Bin](https://jsbin.com/lolome/edit?html,output) is a helpful template. + + +A good bug report shouldn't leave others needing to chase you up for more +information.

All these details will help people to fix +any potential bugs. + +Example: + +> Short and descriptive example bug report title +> +> A summary of the issue and the browser/OS environment in which it occurs.

If it finds any errors, it will post a follow-up comment on the issue and point out the errors. If this happens with an example you've posted, please fix the errors and post an updated live example. If you opened a bug report, please check whether the bug still occurs with your revised, valid live example. If the bug no longer occurs, it was probably due to your invalid HTML rather than something in Bootstrap and we'd appreciate it if you could close out the GitHub issue. + + +## Feature requests + +Feature requests are welcome. But take a moment to find out whether your idea +fits with the scope and aims of the project. It's up to *you* to make a strong +case to convince the project's developers of the merits of this feature. Please +provide as much detail and context as possible. + + +## Pull requests + +Good pull requests—patches, improvements, new features—are a fantastic +help. They should remain focused in scope and avoid containing unrelated +commits. + +**Please ask first** before embarking on any significant pull request (e.g. +implementing features, refactoring code, porting to a different language), +otherwise you risk spending a lot of time working on something that the +project's developers might not want to merge into the project. + +Please adhere to the [coding guidelines](#code-guidelines) used throughout the +project (indentation, accurate comments, etc.) and any other requirements +(such as test coverage). + +**Do not edit `bootstrap.css`, or `bootstrap.js` +directly!** Those files are automatically generated. You should edit the +source files in [`/bootstrap/scss/`](https://github.com/twbs/bootstrap/tree/master/scss) +and/or [`/bootstrap/js/`](https://github.com/twbs/bootstrap/tree/master/js) instead. + +Similarly, when contributing to Bootstrap's documentation, you should edit the +documentation source files in +[the `/bootstrap/docs/` directory of the `master` branch](https://github.com/twbs/bootstrap/tree/master/docs). +**Do not edit the `gh-pages` branch.** That branch is generated from the +documentation source files and is managed separately by the Bootstrap Core Team. + +Adhering to the following process is the best way to get your work +included in the project: + +1. [Fork](https://help.github.com/articles/fork-a-repo/) the project, clone your fork, + and configure the remotes: + + ```bash + # Clone your fork of the repo into the current directory + git clone https://github.com//bootstrap.git + # Navigate to the newly cloned directory + cd bootstrap + # Assign the original repo to a remote called "upstream" + git remote add upstream https://github.com/twbs/bootstrap.git + ``` + +2. If you cloned a while ago, get the latest changes from upstream: + + ```bash + git checkout master + git pull upstream master + ``` + +3. Create a new topic branch (off the main project development branch) to + contain your feature, change, or fix: + + ```bash + git checkout -b + ``` + +4. Commit your changes in logical chunks. Please adhere to these [git commit + message guidelines](http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html) + or your code is unlikely be merged into the main project. Use Git's + [interactive rebase](https://help.github.com/articles/about-git-rebase/) + feature to tidy up your commits before making them public. + +5. Locally merge (or rebase) the upstream development branch into your topic branch: + + ```bash + git pull [--rebase] upstream master + ``` + +6. Push your topic branch up to your fork: + + ```bash + git push origin + ``` + +7. [Open a Pull Request](https://help.github.com/articles/about-pull-requests/) + with a clear title and description against the `master` branch. + +**IMPORTANT**: By submitting a patch, you agree to allow the project owners to +license your work under the terms of the [MIT License](LICENSE) (if it +includes code changes) and under the terms of the +[Creative Commons Attribution 3.0 Unported License](docs/LICENSE) +(if it includes documentation changes). + +### Pull request bots + +[@twbs-rorschach](https://github.com/twbs-rorschach) is a Bootstrap bot that hangs out in our GitHub issue tracker and automatically checks all pull requests for a few simple common mistakes. It's possible that Rorschach might leave a comment on your pull request and then close it. If that happens, simply fix the problem(s) mentioned in the comment (there should be link(s) in the comment explaining the problem(s) in detail) and then either: + +* Push the revised version to your pull request's branch and post a comment on the pull request saying that you've fixed the problem(s). One of the Bootstrap Core Team members will then come along and reopen your pull request. +* Or you can just open a new pull request for your revised version. + +[@twbs-savage](https://github.com/twbs-savage) is a Bootstrap bot that automatically runs cross-browser tests (via [Sauce](https://saucelabs.com/) and Travis CI) on JavaScript pull requests. Savage will leave a comment on pull requests stating whether cross-browser JS tests passed or failed, with a link to the full Travis build details. If your pull request fails, check the Travis log to see which browser + OS combinations failed. Each browser test in the Travis log includes a link to a Sauce page with details about the test. On those details pages, you can watch a screencast of the test run to see exactly which unit tests failed. + + +## Code guidelines + +### HTML + +[Adhere to the Code Guide.](http://codeguide.co/#html) + +- Use tags and elements appropriate for an HTML5 doctype (e.g., self-closing tags). +- Use CDNs and HTTPS for third-party JS when possible. We don't use protocol-relative URLs in this case because they break when viewing the page locally via `file://`. +- Use [WAI-ARIA](https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA) attributes in documentation examples to promote accessibility. + +### CSS + +[Adhere to the Code Guide.](http://codeguide.co/#css) + +- When feasible, default color palettes should comply with [WCAG color contrast guidelines](https://www.w3.org/TR/WCAG20/#visual-audio-contrast). +- Except in rare cases, don't remove default `:focus` styles (via e.g. `outline: none;`) without providing alternative styles. See [this A11Y Project post](http://a11yproject.com/posts/never-remove-css-outlines/) for more details. + +### JS + +- No semicolons (in client-side JS) +- 2 spaces (no tabs) +- strict mode +- "Attractive" +- Don't use [jQuery event alias convenience methods](https://github.com/jquery/jquery/blob/master/src/event/alias.js) (such as `$().focus()`). Instead, use [`$().trigger(eventType, ...)`](https://api.jquery.com/trigger/) or [`$().on(eventType, ...)`](https://api.jquery.com/on/), depending on whether you're firing an event or listening for an event.

We don't use protocol-relative URLs in this case because they break when viewing the page locally via `file://`. -- Use [WAI-ARIA](https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA) attributes in documentation examples to promote accessibility. - -### CSS - -- CSS changes must be done in `.less` files first, never just in the compiled `.css` files. -- Adhere to the [CSS property order](http://markdotto.com/2011/11/29/css-property-order/). -- Multiple-line approach (one property and value per line). -- Always a space after a property's colon (e.g., `display: block;` and not `display:block;`). -- End all lines with a semi-colon. -- For multiple, comma-separated selectors, place each selector on its own line. -- Attribute selectors, like `input[type="text"]` should always wrap the attribute's value in double quotes, for consistency and safety (see this [blog post on unquoted attribute values](http://mathiasbynens.be/notes/unquoted-attribute-values) that can lead to XSS attacks). -- Attribute selectors should only be used where absolutely necessary (e.g., form controls) and should be avoided on custom components for performance and explicitness. -- Series of classes for a component should include a base class (e.g., `.component`) and use the base class as a prefix for modifier and sub-components (e.g., `.component-lg`). -- Avoid inheritance and over nesting—use single, explicit classes whenever possible. -- When feasible, default color palettes should comply with [WCAG color contrast guidelines](http://www.w3.org/TR/WCAG20/#visual-audio-contrast). - -### JS - -- No semicolons -- Comma first -- 2 spaces (no tabs) -- strict mode -- "Attractive" - - -## License - -By contributing your code, you agree to license your contribution under the [MIT license](https://github.com/twbs/bootstrap/blob/master/LICENSE). - -Prior to v3.1.0, Bootstrap was released under the Apache License v2.0. - diff --git a/Gemfile b/Gemfile new file mode 100644 index 000000000000..b80761f888f9 --- /dev/null +++ b/Gemfile @@ -0,0 +1,8 @@ +source 'https://rubygems.org' + +group :development, :test do + gem 'jekyll', '~> 3.7.0' + gem 'jekyll-redirect-from', '~> 0.13.0' + gem 'jekyll-sitemap', '~> 1.1.1' + gem 'jekyll-toc', '~> 0.5.1' +end diff --git a/Gemfile.lock b/Gemfile.lock new file mode 100644 index 000000000000..a49115b33386 --- /dev/null +++ b/Gemfile.lock @@ -0,0 +1,80 @@ +GEM + remote: https://rubygems.org/ + specs: + addressable (2.5.2) + public_suffix (>= 2.0.2, < 4.0) + colorator (1.1.0) + concurrent-ruby (1.0.5) + em-websocket (0.5.1) + eventmachine (>= 0.12.9) + http_parser.rb (~> 0.6.0) + eventmachine (1.2.5) + eventmachine (1.2.5-x64-mingw32) + ffi (1.9.18) + ffi (1.9.18-x64-mingw32) + forwardable-extended (2.6.0) + http_parser.rb (0.6.0) + i18n (0.9.1) + concurrent-ruby (~> 1.0) + jekyll (3.7.0) + addressable (~> 2.4) + colorator (~> 1.0) + em-websocket (~> 0.5) + i18n (~> 0.7) + jekyll-sass-converter (~> 1.0) + jekyll-watch (~> 2.0) + kramdown (~> 1.14) + liquid (~> 4.0) + mercenary (~> 0.3.3) + pathutil (~> 0.9) + rouge (>= 1.7, < 4) + safe_yaml (~> 1.0) + jekyll-redirect-from (0.13.0) + jekyll (~> 3.3) + jekyll-sass-converter (1.5.1) + sass (~> 3.4) + jekyll-sitemap (1.1.1) + jekyll (~> 3.3) + jekyll-toc (0.5.1) + nokogiri (~> 1.6) + jekyll-watch (2.0.0) + listen (~> 3.0) + kramdown (1.16.2) + liquid (4.0.0) + listen (3.1.5) + rb-fsevent (~> 0.9, >= 0.9.4) + rb-inotify (~> 0.9, >= 0.9.7) + ruby_dep (~> 1.2) + mercenary (0.3.6) + mini_portile2 (2.3.0) + nokogiri (1.8.1) + mini_portile2 (~> 2.3.0) + nokogiri (1.8.1-x64-mingw32) + mini_portile2 (~> 2.3.0) + pathutil (0.16.1) + forwardable-extended (~> 2.6) + public_suffix (3.0.1) + rb-fsevent (0.10.2) + rb-inotify (0.9.10) + ffi (>= 0.5.0, < 2) + rouge (3.1.0) + ruby_dep (1.5.0) + safe_yaml (1.0.4) + sass (3.5.5) + sass-listen (~> 4.0.0) + sass-listen (4.0.0) + rb-fsevent (~> 0.9, >= 0.9.4) + rb-inotify (~> 0.9, >= 0.9.7) + +PLATFORMS + ruby + x64-mingw32 + +DEPENDENCIES + jekyll (~> 3.7.0) + jekyll-redirect-from (~> 0.13.0) + jekyll-sitemap (~> 1.1.1) + jekyll-toc (~> 0.5.1) + +BUNDLED WITH + 1.16.1 diff --git a/Gruntfile.js b/Gruntfile.js deleted file mode 100644 index ec9fb594e731..000000000000 --- a/Gruntfile.js +++ /dev/null @@ -1,418 +0,0 @@ -/*! - * Bootstrap's Gruntfile - * http://getbootstrap.com - * Copyright 2013-2014 Twitter, Inc. - * Licensed under MIT (https://github.com/twbs/bootstrap/blob/master/LICENSE) - */ - -module.exports = function (grunt) { - 'use strict';

Navigate to the root `/bootstrap` directory, then run `npm install`. npm will look at [package.json](https://github.com/twbs/bootstrap/blob/master/package.json) and automatically install the necessary local dependencies listed there. - -When completed, you'll be able to run the various Grunt commands provided from the command line. - -**Unfamiliar with `npm`? Don't have node installed?** That's a-okay. npm stands for [node packaged modules](http://npmjs.org/) and is a way to manage development dependencies through node.js. [Download and install node.js](http://nodejs.org/download/) before proceeding. - -### Available Grunt commands - -#### Build - `grunt` -Run `grunt` to run tests locally and compile the CSS and JavaScript into `/dist`. **Uses [Less](http://lesscss.org/) and [UglifyJS](http://lisperator.net/uglifyjs/).** - -#### Only compile CSS and JavaScript - `grunt dist` -`grunt dist` creates the `/dist` directory with compiled files. **Uses [Less](http://lesscss.org/) and [UglifyJS](http://lisperator.net/uglifyjs/).** - -#### Tests - `grunt test` -Runs [JSHint](http://jshint.com) and [QUnit](http://qunitjs.com/) tests headlessly in [PhantomJS](http://phantomjs.org/) (used for CI). - -#### Watch - `grunt watch` -This is a convenience method for watching just Less files and automatically building them whenever you save. - -### Troubleshooting dependencies - -Should you encounter problems with installing dependencies or running Grunt commands, uninstall all previous dependency versions (global and local). Then, rerun `npm install`. - - - ## Contributing Please read through our [contributing guidelines](https://github.com/twbs/bootstrap/blob/master/CONTRIBUTING.md).

+// Dev notes
+//
+// Background information on nomenclature and architecture decisions here.
+//
+// - Bootstrap functions, variables, and mixins are included for easy reuse.
+//   Doing so gives us access to the same core utilities provided by Bootstrap.
+//   For example, consistent media queries through those mixins.
+//
+// - Bootstrap's **docs variables** are prefixed with `$bd-`.
+//   These custom colors avoid collision with the components Bootstrap provides.
+//
+// - Classes are prefixed with `.bd-`.
+//   These classes indicate custom-built or modified components for the design
+//   and layout of the Bootstrap docs. They are not included in our builds.
+//
+// Happy Bootstrapping!

+## JavaScript behavior
+
+### Triggers
+
+Enable dismissal of an alert via JavaScript:
+
+{% highlight js %}
+$('.alert').alert()
+{% endhighlight %}
+
+Or with `data` attributes on a button **within the alert**, as demonstrated above:
+
+{% highlight html %}
+
+{% endhighlight %}
+
+Note that closing an alert will remove it from the DOM.
+
+### Methods
+
+| Method | Description |
+| --- | --- |
+| `$().alert()` | Makes an alert listen for click events on descendant elements which have the `data-dismiss="alert"` attribute. (Not necessary when using the data-api's auto-initialization.) |
+| `$().alert('close')` | Closes an alert by removing it from the DOM. If the `.fade` and `.show` classes are present on the element, the alert will fade out before it is removed. |
+| `$().alert('dispose')` | Destroys an element's alert. |
+
+{% highlight js %}$(".alert").alert('close'){% endhighlight %}
+
+### Events
+
+Bootstrap's alert plugin exposes a few events for hooking into alert functionality.
+
+| Event | Description |
+| --- | --- |
+| `close.bs.alert` | This event fires immediately when the close instance method is called. |
+| `closed.bs.alert` | This event is fired when the alert has been closed (will wait for CSS transitions to complete). |
+
+{% highlight js %}
+$('#myAlert').on('closed.bs.alert', function () {
+  // do something…
+})

+{% example html %}
+
+{% endexample %}
+
+Note that depending on how they are used, badges may be confusing for users of screen readers and similar assistive technologies. While the styling of badges provides a visual cue as to their purpose, these users will simply be presented with the content of the badge. Depending on the specific situation, these badges may seem like random additional words or numbers at the end of a sentence, link, or button.
+
+Unless the context is clear (as with the "Notifications" example, where it is understood that the "4" is the number of notifications), consider including additional context with a visually hidden piece of additional text.
+
+{% example html %}
+
+{% endexample %}
+
+## Contextual variations
+
+Add any of the below mentioned modifier classes to change the appearance of a badge.
+
+{% example html %}
+{% for color in site.data.theme-colors %}
+{{ color.name | capitalize }}{% endfor %}
+{% endexample %}
+
+{% capture callout-include %}{% include callout-warning-color-assistive-technologies.md %}{% endcapture %}
+{{ callout-include | markdownify }}
+
+## Pill badges
+
+Use the `.badge-pill` modifier class to make badges more rounded (with a larger `border-radius` and additional horizontal `padding`). Useful if you miss the badges from v3.
+
+{% example html %}
+{% for color in site.data.theme-colors %}
+{{ color.name | capitalize }}{% endfor %}
+{% endexample %}
+
+## Links
+
+Using the contextual `.badge-*` classes on an `` element quickly provide _actionable_ badges with hover and focus states.
+

+{% for color in site.data.theme-colors %}
