Tor Browser 8 onboarding UI bugs

I am splitting the onboarding issues mentioned in legacy/trac#27301 (moved) out into this ticket:

The title of the card needs margin: .onboarding-tour-description > h1 {margin: 16px 0;}

​https://share.riseup.net/#CjGBhXPC7qgxKwwyh4Zljw We really want green ticks' background that matches with illos green. How can we do it? is it css? Does Anto need to provide assets? FYI the green is #00DDB3

The scrollbars - Can we reduce margins or make them % to the windows in order to make them disappear?
