This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The ::-ms-ticks-before CSS pseudo-element is a Microsoft extension that applies one or more styles to the tick marks before the slider track of an <input type="range"> (also known as a slider) control. In a left-to-right layout, these are the ticks above the track. In a top-to-bottom layout, these are the ticks to the left of a track.



These ticks aren't shown by default. To show them, set the control's display CSS property to block.

It is possible to use ::-ms-ticks-after, ::-ms-ticks-before, and ::-ms-track selectors together. However, to do so would create three sets of tick marks, which is not recommended. For the most ideal user experience, use one set of tick marks. To remove tick marks altogether, set the color property to transparent.

You can set these properties on this pseudo-element (other properties are ignored):
