title: Modern alternative for frameset layout
body: <p>Here's my mainpage layout:</p>
  
  <pre><code>&lt;HTML&gt;
  &lt;HEAD&gt;
  
  &lt;/HEAD&gt;
  &lt;FRAMESET&gt;
      &lt;FRAMESET&gt;
          &lt;FRAME name="menu"  src=&lt;%=menu%&gt; &gt;
          &lt;FRAME src=&lt;%=bottom%&gt; &gt;
      &lt;/FRAMESET&gt;
      &lt;FRAMESET&gt;
          &lt;FRAME  src=&lt;%=tittle%&gt;  &gt;
          &lt;FRAME name="center"  src=&lt;%=center%&gt;&gt;
      &lt;/FRAMESET&gt;
  &lt;/FRAMESET&gt;
  </code></pre>
  
  <p></p>
  
  <p>Since this page was build 10 years ago and html5 does not support framesets anymore I'd like to modernize my layout.</p>
  
  <p>Which would be the alternative nowadays?</p>
