# angular-backtop [](https://travis-ci.org/padsbanger/angular-backtop)
A simple *Angular.js* directive to create "Back to top" button when user reaches the end of the page.
You can see a working demo [here](http://padsbanger.github.io/angular-backtop/demo/).
## Installation
Assuming that you already have Angular.js in your app, include *angular-backtop.js* and *angular-backtop.css*.
You can also use Bower, just type:
```js
bower install --save angular-backtop
```
Add directive as your dependency:
```js
var app = angular.module('app', ['angular.backtop']);
```
Create directive element somewhere inside of your ** tag:
```html
Scroll top
```
... and thats all, you have a basic button, that will appear when you start scrolling the page. Click on it to be redirected to the top.
## Options
You can pass some more options to the directive.
- **scroll-speed** - Speed in miliseconds, default value is 600
- **button-theme** - Themes for button, there is *bootstrap*, *dark* & *light*. Default it *light*.
Example:
```html
Take me back
```
