### Features

* Extremely fast. (Using Intersection Observer)

* Lightweight.

* No dependencies.

## Demo

Example page on CodePen [here](https://codepen.io/marlospomin/pen/EbYXqe).

## Install

```bash

# Using npm

$ npm install @marlospomin/turtle

# Using yarn

$ yarn add @marlospomin/turtle

```

Now include turtle and you should be good to go.

```js

// es6

import turtle from '@marlospomin/turtle'

// commonjs

const turtle = require('@marlospomin/turtle')

```

## Usage

Add ```.turtle ``` class to your element(s) and the image path using ```data-src``` attribute according to the example below.

```

If you want to use a *placeholder* for the real image refer it in the ```src``` attribute:

```html



```

Call turtle anywhere in your code.

```js

// Call turtle

turtle()

```

### Configuring

These are the current default options, change them as you see fit.
