Hi,masters,

I added a new Tab "Graph" in SF,and created a new VF page.The page scripts is running well out of  the salesforce envirenment.And if i set "showHeader=false" in the salesforce envirenment,it goes right too.But if i set "showHeader=true",the page displays messy.I thought  it was because of the salesforce's  css.If i'd like to show header(Tabs) and display my VF page at the same time,what can i do to let it displays normally?

Thanks a lot.
