+ <li>The pseudo-elements used by Gecko to style other parts of a range input:
+  <ul>
+   <li>{{cssxref("::-moz-range-thumb")}} represents the indicator that slides in the groove.</li>
+   <li>{{cssxref("::-moz-range-progress")}} represents the lower portion of the track.</li>
+  </ul>
+ </li>
+ <li>Similar pseudo-elements used by other browsers:
+  <ul>
+   <li>{{cssxref("::-webkit-slider-runnable-track")}}, pseudo-element supported by WebKit and Blink (Safari, Chrome, and Opera)</li>
+   <li>{{cssxref("::-ms-track")}}, pseudo-element supported by Internet Explorer and Edge</li>
