I can see you have a lot of questions about statuspage's html and layoyt, but there's a lot of potential for duplication of effort in answering them all separately.
I think you should gather together all the questions you've got and ask them in one big question. You'll still probably get separate answers for most of them, but if it's all in one place, you won't be having to jump around and all the answerers won't be repeating or contradicting each other in different threads. It'll also make it easier to turn into a support or improvement request if it needs to go to Atlassian.
