How to customize the page that appears when a customer unsubscribes from my email

[AreaMan]

I was able to customize the main text on the page through my settings, but I'd also like to remove the default title above that text (my company name in huge letters) and can't figure out how. Anyone know how?

Pixel Union came through with a workaround. Happy to share if anyone needs it.

Go to Themes > Edit Code > Assets > theme.css.liquid

Then paste this code at the bottom.
