Page Layout

Hi,

i have created different page layouts based on the article page layout. But there's one problem which i cannot resolve:

when a user creates a new page based on my page layout ..the my new page layout works excellent. But when the page is rendered in the browser it's being displayed totally different then i expected. After lot's of restyling i still cannot seem to get it correct.

Are there any tips form which i can build on... Things i need to consider... maybe some first class tips

kind regards and many tnx in advance...

Joost
