<iron-label>

<iron-label> provides a version of the <label> element that works with Custom Elements as well as native elements.

All text in the iron-label will be applied to the target element as a screen-reader accessible description.

There are three ways to use iron-label to target an element:

1. place an element inside iron-label and some text:

 <iron-label>
   Label for the Button
   <paper-button>button</paper-button>
 </iron-label>

1. place some elements inside iron-label and target one with the iron-label-target attribute. The other elements will provide the label for that element Note: This is not necessary if the element you want to label is the first element child of iron-label:

 <iron-label>
   <span>Label for the Button</span>
   <paper-button iron-label-target>button</paper-button>
 </iron-label>

 <iron-label>
   <paper-button>button</paper-button>
   <span>Label for the Button</span>
 </iron-label>

1. Set the for attribute on the iron-label element with the id of the target element in the same document or ShadowRoot:

 <iron-label for="foo">
   Context for the button with the "foo" class"
 </iron-label>
 <paper-button id="foo">Far away button</paper-button>

All taps on the iron-label will be forwarded to the "target" element.
