title: Angular Material tab height
body: <p>I am trying to have a full page Angular Material tab which has tabs which are full height and have a centered message. I have created <a href="https://stackblitz.com/edit/angular-fad56q" rel="noreferrer">this stakblitz</a> as I can't get it to work. The fxFill's don't seem to Fill and I am not sure if this is an issue with the Flexbox layout or Angular Material. I don't want to force a height as within each tab as that seems to defeat the point of flexible layouts.</p>
  
  <p>Am sure its simple but help a poor confused developer who is used to Bootstrap grid :)</p>
  
  <p><strong>UPDATE</strong>
  Adding <em>height: calc(100vh - 100px);</em> to the parent div and then also to the tall.component div makes things work but <em><strong>surely this is a bad solution</strong></em></p>
