Installation

$ bower install -S arsnebula/nebula-sidebar-layout

Getting Started

Import the element:

<link rel="import" href="/bower_components/nebula-sidebar-layout/nebula-sidebar-layout.html">

The element utilizes offscreen positioning for the drawer when collapsed, so the body and and other parent elements should be set to fill the browser screen. The following is a sample stylesheet for ensuring the body matches the viewport.

<head>
  <style>
    html, body {
      position: relative;
      border: 0;
      margin: 0;
      padding: 0;
      min-height: 100vh;
      width: 100%;
      height: 100%;
      overflow: hidden;
      overflow-y: auto;
      box-sizing: border-box;
    }
  </style>
</head>

Add the element.

<nebula-sidebar-layout
  breakpoint="(max-width: 960px)"
  collapsed="{{collapsed}}"
  opened="{{opened}}"
  on-changed="_onChanged">

  <div slot="sidebar"></div>
  <div slot="content"></div>
</nebula-sidebar-layout>

Style the element.

nebula-sidebar-layout {
  --nebula-sidebar-layout-backdrop-color: hsla(0, 0%, 0%, 0.6);
  --nebula-sidebar-layout-transition-duration: 0.25s;
  --nebula-sidebar-layout-sidebar: {
    border-right: 1px solid silver;
  }
}
