Material design: Toolbars

paper-toolbar is a horizontal bar containing items that can be used for label, navigation, search and actions. The items placed inside the paper-toolbar are projected into a class="horizontal center layout" container inside of paper-toolbar's Shadow DOM. You can use flex attributes to control the items' sizing.

Example:

<paper-toolbar>
  <paper-icon-button icon="menu" on-tap="menuAction"></paper-icon-button>
  <div class="title">Title</div>
  <paper-icon-button icon="more-vert" on-tap="moreAction"></paper-icon-button>
</paper-toolbar>

paper-toolbar has a standard height, but can made be taller by setting tall class on the paper-toolbar. This will make the toolbar 3x the normal height.

<paper-toolbar class="tall">
  <paper-icon-button icon="menu"></paper-icon-button>
</paper-toolbar>

Apply medium-tall class to make the toolbar medium tall. This will make the toolbar 2x the normal height.

<paper-toolbar class="medium-tall">
  <paper-icon-button icon="menu"></paper-icon-button>
</paper-toolbar>

When tall, items can pin to either the top (default), middle or bottom. Use middle class for middle content and bottom class for bottom content.

<paper-toolbar class="tall">
  <paper-icon-button icon="menu"></paper-icon-button>
  <div class="middle title">Middle Title</div>
  <div class="bottom title">Bottom Title</div>
</paper-toolbar>

For medium-tall toolbar, the middle and bottom contents overlap and are pinned to the bottom. But middleJustify and bottomJustify attributes are still honored separately.

To make an element completely fit at the bottom of the toolbar, use fit along with bottom.

<paper-toolbar class="tall">
  <div id="progressBar" class="bottom fit"></div>
</paper-toolbar>

When inside a paper-header-panel element, the class .animate is toggled to animate the height change in the toolbar.
