query regarding spacing and background of text

[Sriram-Kumar1]

Hello folks,

have been playing around with mermaid after I heard pod cast on software engineering radio. very useful project.
I have two problems to solve,

pls look at the sample code here

flowchart LR
subgraph DP["<font size=4 , color=#286> Development Phase"]
A("Developer") --Local Branch--> B("Dev Branch")
B--Code Reveiw -->C(Release Branch)
C--Release Notes to QA-->D("Release Tag")
class A,B,C,D dblue
end

1. in this, the first problem is It would be better if there is a space between the title and the first node. not sure how to go about it
2. is there a way I can choose background color for Local Branch to be same as the default background color?. its picking a grey background for the label not sure if there is a way to change that.

thanks a ton
