title: CSS/HTML: Set default container height
body: <p>Hey, how can i set a default container height on a element?</p>
  
  <p>My example have a div like this:</p>
  
  <pre><code>&lt;div id="container"&gt;
  text text
  &lt;/div&gt;
  </code></pre>
  
  <p>Then i want the height default at 300px; so it gets large even with only this text^.</p>
  
  <p>With DEFAULT i mean also, that if the text exceeds 300px the height should just be bigger like there isnt specified a height.</p>
