I am running an APEX application embedded in a web app (displaying the APEX pages with an IFRAME). My APEX app consists only of a home page with a list item on it and all other pages are Interactive Reports. I want the APEX app to appear seamless and use the CSS from main web app on all the APEX IR's and Home page. I also don't want to display all the other pieces (title, logout links tab etc.). What is the best way to do this?
