Center HTML in Touch Bar button?

Using a styled html span in a button moves it to the left. Margin, padding, and width styling doesn't seem to work, and the center tag seems to insert a new line below.

Is there a way to get html styled text to be centered in a button?

Currently using this output:

<html><span style='font-family:system-ui; font-weight: 300;color:#fff;font-size:18;'>The Cramps &bull; Georgia Lee Brown</span></html>
