@brassy- I found a minor inconsistency that the way you describe colors is different from other pages. How about using Gray 90 instead of Gray-90?

(Just leave it here) A few questions regarding the visual examples and content:

1. Are these two message bars dismissable?

2. I felt a little confused about having 2 items in this image. Do we have the 2nd one because we need to mark some specs on it?

3. Button text in uppercase?

No.

2. I felt a little confused about having 2 items in this image. Do we have the 2nd one because we need to mark some specs on it?

Good point, I'll update the image today.

3. Button text in uppercase?

Fixing it right now, good catch!
