Multiple <progress> elements on a page with different colors

Question

I'm using the element and I've found good instructions on [styling] (http://html5doctor.com/the-progress-element/).

I'd like to have more than one progress bar on a page and I'd like them to have different fill/value colors. Is this possible? Can I do this by tweaking my CSS? Or an I better off rolling my own? Thanks!

.current-roll {
  -webkit-appearance: none;
  width: 80%;
  height: 25px;
  /* next line does nothing */
  color: #f7a700
}
.previous-roll {
  -webkit-appearance: none;
  width: 80%;
  height: 25px;
  /* next line does nothing */
  color: #98c11e
}
progress::-webkit-progress-bar {
  background: #d8d8d8;
}
progress::-webkit-progress-value {
  background: #f7a700;
}

<p>Orange bar</p>
<progress class="current-roll" value="0.5"></progress>

<p>Green bar</p>
<progress class="previous-roll" value="0.75"></progress>

Answer 1

progress::-webkit-progress-value is what changes the progress bar color.

Example

progress.current-roll::-webkit-progress-value {
  background: #f7a700;
}
