## Include [Flex Layout](https://github.com/angular/flex-layout) in your CLI application > Above is snapshot of a [Online Demos](https://tburleson-layouts-demos.firebaseapp.com/#/docs) using @angular/flex-layout
### Include `@angular/flex-layout` as detailed below: Install the library and add the dependency to package.json... ```bash npm install --save @angular/flex-layout ``` Or install the nightly build using: ```bash npm i --save @angular/flex-layout-builds ``` Import the Angular Flex-Layout NgModule into your app module... ```javascript //in src/app/app.module.ts import { FlexLayoutModule } from '@angular/flex-layout'; // other imports @NgModule({ imports: [ ... FlexLayoutModule ], ... }) ``` Run `ng serve` to run your application in develop mode, and navigate to `http://localhost:4200`
### Sample App Add the following to `src/app/app.component.css`... ```css [fxLayout="column"] { border: 1px solid;padding:4px; margin-top:50px; }, [fxFlex]{ padding:5px;}, h3 { padding-top:20px; }, .header { background-color: lightyellow; }, .left { background-color: lightblue; }, .right { background-color: pink; } ``` To verify flex-layout has been set up correctly, change `src/app/app.component.html` to the following... ```html

{{title}}

LEFT: 20% wide
RIGHT: 80% wide
``` After saving this file, return to the browser to see the very ugly but demonstrative flex-layout. ![screen shot 2017-08-05 at 7 20 05 pm](https://user-images.githubusercontent.com/210413/28999629-35c566a0-7a13-11e7-8d36-1d1a2244443c.png) Among what you should see are - a light yellow header that is the entire width of the window, sitting directly atop 2 columns. Of those 2 columns, the left column should be light blue, and 20% wide, while the right column is pink, 80% to start, and will flex with window (re)size.
