title: How to get CSS to select ID that begins with a string (not in Javascript)?
body: <p>If the HTML has elements like this:</p>
  
  <pre><code>id="product42"
  id="product43"
  ...
  </code></pre>
  
  <p>How do I match all of those id's starting with "product"?</p>
  
  <p>I've seen answers that do this exactly using javascript, but how to do it with only CSS?</p>
