  <h2>Star rating widget with SVG <code>&lt;use&gt;</code></h2>
  <p>I needed a star rating widget that uses SVG and is able to highlight half star (like: 4.5 stars) - and this is my solution.</p>
  <p>It uses a bit of jQuery, because unlike psedu classes, I had to position it relatively to a container, so sibiling selectors are out. To show the finished rating system, a little script is used. It adds a class to the parent, so that the SVG can change the fill. </p>

  <p>One obvious enhancement would be to apply gradient to the SVG, and it is something I plan on implementing as soon as my queue clears up!</p>
