Any way to lessen the height of a widget-slider?

Attempted to search all over this site and cant seem to find a way to make a widget slider less tall. is this possible?

What do you mean?
This widget is 1 unit high

You can only make it as small as a width of a single cell on the dashboard.

However, in the dashboard settings on the Advanced tab, you can increase the Number of Columns setting, which gives you more fine-grained control of the widget size (i.e. each cell will be smaller). You could use this to make the slider widget more narrow than the other widgets on the dashboard. I don’t know any other way to accomplish what you want to do.
