Usage

Implementing Slideout.js into your project is easy.

First of all, you'll need to create your markup. You should have a menu (#menu) and a main content (#panel) into your body.

<nav id="menu">
  <header>
    <h2>Menu</h2>
  </header>
</nav>

<main id="panel">
  <header>
    <h2>Panel</h2>
  </header>
</main>

Add the Slideout.js styles (index.css) in your web application.

body {
  width: 100%;
  height: 100%;
}

.slideout-menu {
  position: fixed;
  left: 0;
  top: 0;
  bottom: 0;
  right: 0;
  z-index: 0;
  width: 256px;
  overflow-y: auto;
  -webkit-overflow-scrolling: touch;
  display: none;
}

.slideout-panel {
  position:relative;
  z-index: 1;
}

.slideout-open,
.slideout-open body,
.slideout-open .slideout-panel {
  overflow: hidden;
}

.slideout-open .slideout-menu {
  display: block;
}

Then you just include Slideout.js and create a new instance with some options:

<script src="dist/slideout.min.js"></script>
<script>
  var slideout = new Slideout({
    'panel': document.getElementById('panel'),
    'menu': document.getElementById('menu'),
    'padding': 256,
    'tolerance': 70
  });
</script>
