    <anypoint-tab>Tab one</anypoint-tab>

</div>

When the fitContainer property is set the tabs expands to full width of the container.

  <anypoint-tab>Tab one</anypoint-tab>
  <anypoint-tab>Tab two</anypoint-tab>
  <anypoint-tab>Tab three</anypoint-tab>
  <anypoint-tab>Tab four</anypoint-tab>
</anypoint-tabs>

Otherwise they stay aligned to left/right (depending on dir value)
