paper-toolbar
paper-toolbar is a horizontal bar containing items that can be used for
label, navigation, search and actions. The items place 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" 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="title middle">Middle Title</div>
<div class="title bottom">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.
