Drag Slider to Adjust Rating

All you need for a fancy star rating display is the `meter` element and some CSS.

Chrome (65 and earlier) supports pseudo elements on `meter::before` natively. Here, we add a `span` element with the `presentation` aria role in order to give non-supporting browsers a leg up.

For an interactive control, you could easily substitute the `meter` element for `input type="range"` and adjust the css accordingly.
