title: Making part of a div transparent
body: <p><img src="https://i.stack.imgur.com/vqEMk.png" alt="Example Image"></p>
  
  <p>I'm trying to do something like this in HTML. It's a header, at the very top of the page. The checkerboard area must be transparent.</p>
  
  <p>I can't think of a good way to do this without using like 15 divs.</p>
