  # Include [Bootstrap](http://getbootstrap.com/)
  
  [Bootstrap](http://getbootstrap.com/) is a popular CSS framework which can be used within an Angular project.
  This guide will walk you through adding bootstrap to your Angular CLI project and configuring it to use bootstrap.
  
  ## Using CSS
  
  ### Getting Started
  
  Create a new project and navigate into the project
  
  ```
  ng new my-app
  cd my-app
  ```
  
  ### Installing Bootstrap
  
  With the new project created and ready you will next need to install bootstrap to your project as a dependency.
  Using the `--save` option the dependency will be saved in package.json
  
  ```sh
  # version 3.x
  npm install bootstrap --save
  
  # version 4.x
  npm install bootstrap@next --save
  ```
  
  ### Configuring Project
  
  Now that the project is set up it must be configured to include the bootstrap CSS.
  
  - Open the file `.angular-cli.json` from the root of your project.
  - Under the property `apps` the first item in that array is the default application.
  - There is a property `styles` which allows external global styles to be applied to your application.
  - Specify the path to `bootstrap.min.css`
  
    It should look like the following when you are done:
    ```json
    "styles": [
      "../node_modules/bootstrap/dist/css/bootstrap.min.css",
      "styles.css"
    ],
    ```
  
  **Note:** When you make changes to `.angular-cli.json` you will need to re-start `ng serve` to pick up configuration changes.
  
  ### Testing Project
  
  Open `app.component.html` and add the following markup:
  
  ```html
  <button class="btn btn-primary">Test Button</button>
  ```
  
  With the application configured, run `ng serve` to run your application in develop mode.
  In your browser navigate to the application `localhost:4200`.
  Verify the bootstrap styled button appears.
  
  ## Using SASS
  
  ### Getting Started
  
  Create a new project and navigate into the project
  
  ```
  ng new my-app --style=scss
  cd my-app
  ```
  
  ### Installing Bootstrap
  
  ```sh
  # version 3.x
  npm install bootstrap-sass --save
  
  # version 4.x
  npm install bootstrap@next --save
  ```
  
  ### Configuring Project
  
  Create an empty file `_variables.scss` in `src/`.
  
  If you are using `bootstrap-sass`, add the following to `_variables.scss`:
  
  ```sass
  $icon-font-path: '../node_modules/bootstrap-sass/assets/fonts/bootstrap/';
  ```
  
  In `styles.scss` add the following:
  
  ```sass
  // version 3
  @import 'variables';
  @import '../node_modules/bootstrap-sass/assets/stylesheets/_bootstrap';
  
  // version 4
  @import 'variables';
  @import '../node_modules/bootstrap/scss/bootstrap';
  ```
  
  ### Testing Project
  
  Open `app.component.html` and add the following markup:
  
  ```html
  <button class="btn btn-primary">Test Button</button>
  ```
  
  With the application configured, run `ng serve` to run your application in develop mode.
  In your browser navigate to the application `localhost:4200`.
  Verify the bootstrap styled button appears.
  To ensure your variables are used open `_variables.scss` and add the following:
  
  ```sass
  $brand-primary: red;
  ```
  
  Return the browser to see the font color changed.
