Dear,I just got back into web dev, now i have a small question.I'm bussy on my new portfolio and i want it to be a single page portfolio.So i setup my site in sections ( Image rotator , home , service , contact ,...)and i am wondering how to make a menu that starts on the botom of the image rotator section and as i scroll down it will rise to the top of the page and stay there even if i scroll further then the rotator section.The following link will give you an idea of what i mean .http://themestrong.com/demo/argo_wp/Also , while i'm at it . does someone also know how to make a "Back to Top" button that will display if i enter the second Section ?Thanks in advance !Jochem.
