iron-a11y-announcer
===================
`iron-a11y-announcer` is a singleton element that is intended to add a11y
to features that require on-demand announcement from screen readers. In
order to make use of the announcer, it is best to request its availability
in the announcing element.
Example:
Polymer({
is: 'x-chatty',
attached: function() {
// This will create the singlton element if it has not
// been created yet:
Polymer.IronA11yAnnouncer.requestAvailability();
}
});
After the `iron-a11y-announcer` has been made available, elements can
make announces by firing bubbling `iron-announce` events.
Example:
this.fire('iron-announce', {
text: 'This is an announcement!'
}, { bubbles: true });
Note: announcements are only audible if you have a screen reader enabled.
