# Bootstrap for Sass [](http://badge.fury.io/rb/bootstrap-sass) [](http://badge.fury.io/bo/bootstrap-sass-official) [](http://travis-ci.org/twbs/bootstrap-sass)
|
|
|
|
`bootstrap-sass` is a Sass-powered version of [Bootstrap](http://github.com/twbs/bootstrap), ready to drop right into your Sass powered applications.
|
|
|
|
## Installation
|
|
|
|
Please see the appropriate guide for your environment of choice:
|
|
|
|
### a. Ruby on Rails
|
|
|
|
`bootstrap-sass` is easy to drop into Rails with the asset pipeline.
|
|
|
|
In your Gemfile you need to add the `bootstrap-sass` gem, and ensure that the `sass-rails` gem is present - it is added to new Rails applications by default.
|
|
|
|
```ruby
|
|
gem 'sass-rails', '>= 3.2'
|
|
gem 'bootstrap-sass', '~> 3.1.1'
|
|
```
|
|
|
|
`bundle install` and restart your server to make the files available through the pipeline.
|
|
|
|
|
|
#### Rails 3.2.x
|
|
|
|
Rails 3.2 is [no longer maintained for bugfixes](http://guides.rubyonrails.org/maintenance_policy.html), and you should upgrade as soon as possible.
|
|
|
|
If you must use it, make sure bootstrap-sass is moved out of the `:assets` group.
|
|
This is because, by default in Rails 3.2, assets group gems are not required in `production`.
|
|
However, for pre-compilation to succeed in production, `bootstrap-sass` gem must be required.
|
|
|
|
Starting with bootstrap-sass v3.1.1.1, due to the structural changes from upstream you will need these
|
|
backported asset pipeline gems on Rails 3.2. There is more on why this is necessary in
|
|
https://github.com/twbs/bootstrap-sass/issues/523 and https://github.com/twbs/bootstrap-sass/issues/578.
|
|
|
|
```ruby
|
|
gem 'sprockets-rails', '=2.0.0.backport1'
|
|
gem 'sprockets', '=2.2.2.backport2'
|
|
gem 'sass-rails', github: 'guilleiguaran/sass-rails', branch: 'backport'
|
|
```
|
|
|
|
### b. Compass without Rails
|
|
|
|
Install the gem
|
|
```sh
|
|
gem install bootstrap-sass
|
|
```
|
|
|
|
If you have an existing Compass project:
|
|
|
|
```ruby
|
|
# config.rb:
|
|
require 'bootstrap-sass'
|
|
```
|
|
|
|
```console
|
|
bundle exec compass install bootstrap
|
|
```
|
|
|
|
If you are creating a new Compass project, you can generate it with bootstrap-sass support:
|
|
|
|
```console
|
|
bundle exec compass create my-new-project -r bootstrap-sass --using bootstrap
|
|
```
|
|
|
|
or, alternatively, if you're not using a Gemfile for your dependencies:
|
|
|
|
```console
|
|
compass create my-new-project -r bootstrap-sass --using bootstrap
|
|
```
|
|
|
|
This will create a new Compass project with the following files in it:
|
|
|
|
* [_bootstrap-variables.scss](/templates/project/_bootstrap-variables.sass.erb) - all of bootstrap variables (override them here).
|
|
* [styles.scss](/templates/project/styles.sass) - main project SCSS file, import `variables` and `bootstrap`.
|
|
|
|
Some bootstrap-sass mixins may conflict with the Compass ones.
|
|
If this happens, change the import order so that Compass mixins are loaded later.
|
|
|
|
### c. Ruby without Compass / Rails
|
|
|
|
Require the gem, and load paths and Sass helpers will be configured automatically:
|
|
|
|
```ruby
|
|
require 'bootstrap-sass'
|
|
```
|
|
|
|
### d. Node.js / Bower
|
|
|
|
Using bootstrap-sass as a Bower package is still being tested. It is compatible with node-sass 0.8.3+. You can install it with:
|
|
|
|
```bash
|
|
bower install bootstrap-sass-official
|
|
```
|
|
|
|
`bootstrap-sass` is taken so make sure you use the command above.
|
|
|
|
Sass, JS, and all other assets are located at [assets](/assets).
|
|
|
|
By default, `bower.json` main field list only the main `bootstrap.scss` and all the static assets (fonts and JS).
|
|
This is compatible by default with asset managers such as [wiredep](https://github.com/taptapship/wiredep).
|
|
|
|
#### Mincer
|
|
|
|
If you use [mincer][mincer] with node-sass, import bootstrap into a `.css.ejs.scss` file like so:
|
|
|
|
```scss
|
|
// Import mincer asset paths helper integration
|
|
@import "bootstrap-mincer";
|
|
@import "bootstrap";
|
|
```
|
|
|
|
See also this [example manifest.js](/test/dummy_node_mincer/manifest.js) for mincer.
|
|
|
|
#### Number precision
|
|
|
|
bootstrap-sass [requires](https://github.com/twbs/bootstrap-sass/issues/409) minimum [Sass number precision][sass-precision] of 10 (default is 5).
|
|
|
|
When using ruby Sass compiler with the bower version you can enforce the limit with:
|
|
|
|
```ruby
|
|
::Sass::Script::Number.precision = [10, ::Sass::Script::Number.precision].max
|
|
```
|
|
|
|
Note that libsass and node-sass do not currently support the precision option, due to an open bug ([bug #364](https://github.com/sass/libsass/issues/364)) in libsass.
|
|
|
|
#### JS and fonts
|
|
|
|
Assets are discovered automatically on Rails, Sprockets, Compass, and Node + Mincer, using native asset path helpers.
|
|
|
|
Otherwise the fonts are referenced as:
|
|
|
|
```sass
|
|
"#{$icon-font-path}#{$icon-font-name}.eot"
|
|
```
|
|
|
|
`$icon-font-path` defaults to `bootstrap/`.
|
|
|
|
When not using an asset pipeline, you can copy fonts and JS from bootstrap-sass, they are located at [assets](/assets):
|
|
|
|
```bash
|
|
mkdir public/fonts
|
|
cp -r $(bundle show bootstrap-sass)/assets/fonts/ public/fonts/
|
|
mkdir public/javascripts
|
|
cp -r $(bundle show bootstrap-sass)/assets/javascripts/ public/javascripts/
|
|
```
|
|
|
|
## Usage
|
|
|
|
### Sass
|
|
|
|
Import Bootstrap into a Sass file (for example, `application.css.scss`) to get all of Bootstrap's styles, mixins and variables!
|
|
We recommend against using `//= require` directives, since none of your other stylesheets will be [able to access][antirequire] the Bootstrap mixins or variables.
|
|
|
|
```scss
|
|
@import "bootstrap";
|
|
```
|
|
|
|
You can also include optional bootstrap theme:
|
|
|
|
```scss
|
|
@import "bootstrap/theme";
|
|
```
|
|
|
|
The full list of bootstrap variables can be found [here](http://getbootstrap.com/customize/#less-variables). You can override these by simply redefining the variable before the `@import` directive, e.g.:
|
|
|
|
```scss
|
|
$navbar-default-bg: #312312;
|
|
$light-orange: #ff8c00;
|
|
$navbar-default-color: $light-orange;
|
|
|
|
@import "bootstrap";
|
|
```
|
|
|
|
You can also import components explicitly. To start with a full list of modules copy this file from the gem:
|
|
|
|
```bash
|
|
cp $(bundle show bootstrap-sass)/assets/stylesheets/bootstrap.scss \
|
|
app/assets/stylesheets/bootstrap-custom.scss
|
|
```
|
|
Comment out components you do not want from `bootstrap-custom`.
|
|
|
|
In `application.sass`, replace `@import 'bootstrap'` with:
|
|
|
|
```scss
|
|
@import 'bootstrap-custom';
|
|
```
|
|
|
|
### Javascript
|
|
|
|
We have a helper that includes all Bootstrap javascripts. If you use Rails (or Sprockets separately),
|
|
put this in your Javascript manifest (usually in `application.js`) to load the files in the [correct order](/assets/javascripts/bootstrap.js):
|
|
|
|
```js
|
|
// Loads all Bootstrap javascripts
|
|
//= require bootstrap
|
|
```
|
|
|
|
You can also load individual modules, provided you also require any dependencies. You can check dependencies in the [Bootstrap JS documentation][jsdocs].
|
|
|
|
```js
|
|
//= require bootstrap/scrollspy
|
|
//= require bootstrap/modal
|
|
//= require bootstrap/dropdown
|
|
```
|

### Upstream Converter
|
|
|
|
Keeping bootstrap-sass in sync with upstream changes from Bootstrap used to be an error prone and time consuming manual process. With Bootstrap 3 we have introduced a converter that automates this.
|
|
|
|
**Note: if you're just looking to *use* Bootstrap 3, see the [installation](#installation) section above.**
|
|
|
|
Upstream changes to the Bootstrap project can now be pulled in using the `convert` rake task.
|
|
|
|
Here's an example run that would pull down the master branch from the main [twbs/bootstrap](https://github.com/twbs/bootstrap) repo:
|
|
|
|
rake convert
|
|
|
|
This will convert the latest LESS to Sass and update to the latest JS.
|
|
To convert a specific branch or version, pass the branch name or the commit hash as the first task argument:
|
|
|
|
rake convert[e8a1df5f060bf7e6631554648e0abde150aedbe4]
|
|
|
|
The latest converter script is located [here][converter] and does the following:
|
|
|
|
* Converts upstream bootstrap LESS files to its matching SCSS file.
|
|
* Copies all upstream JavaScript into `assets/javascripts/bootstrap`
|
|
* Generates a javascript manifest at `assets/javascripts/bootstrap.js`
|
|
* Copies all upstream font files into `assets/fonts/bootstrap`
|
|
* Sets `Bootstrap::BOOTSTRAP_SHA` in [version.rb][version] to the branch sha.
|
|
|
|
This converter fully converts original LESS to SCSS. Conversion is automatic but requires instructions for certain transformations (see converter output).
|
|
Please submit GitHub issues tagged with `conversion`.
