Most (all) my knowledge dates back to html3 and the early table-infected times - So I have a lot of 'catching up' to do 8^)

Unfortunately I have a problem which cannot wait for my pretty slow progress:

As a newcomer, [img] is OFF so I can't show you directly but I want to make a CSS3/Pie Box with round corners AND a headline with its own style like box no. 2 on

since it shall work in IE too I thought I would start asking for help around here.

Pls. bear with me and write as grandpa-friendly as possible
