Feature Description

Currently slider component has hard-coded height of 48px. In our app we need 34px height (we are replacing jquery slider control with material slider). We cannot simply change the height of the component since internal elements (i.e. thumb) depend on the component height. Thereby please expose the token that can be used to change height of the slider component.

Use Case

Expose token to customize height of slider component.
