# Include [Flex Layout](https://github.com/angular/flex-layout) in your CLI application Include Angular Flex layout as detailed above. Install the `@angular/flex-layout` library and add the dependency to package.json... ```bash npm install --save @angular/flex-layout ``` 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` Add the following to `src/app/app.component.css`... ```css .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. 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. ### More Info - [Installation](https://github.com/angular/flex-layout#installation) - [API Overview](https://github.com/angular/flex-layout/wiki/API-Overview) - [Demo](https://tburleson-layouts-demos.firebaseapp.com/#/docs)
