title: How to split page into 4 equal parts?
body: <p>I want to divide my page into four equal parts, each of same height and width <em>(50-50%)</em>.</p>
  
  <p>I don't want to use JavaScript. I want blocks <em>(<code>&lt;div&gt;</code>s)</em> to be resized automatically <em>(and relatively)</em> if the browser window is resized.</p>
  
  <p>I have not worked with CSS for a long time. I've no idea how to handle this.</p>
