Dashboard Slider Customization

Trying to customize the width of the slider (button and line) specifically for the bulb tile. I would like to make them smaller so that it can free up some real estate in the tile. Can this be done?

No, currently this can't be done. I will add it to the list of feature requests.

I am familiar with CSS and even if it could be exposed in the advanced that would be nice! Thank you!

That would be awesome! The Slider gets in the way and my finger winds up hitting it and changing the level when I go to turn on or off.
