I have googled all day, and searched this website for more than one hour, but the final solution must be hidden, somewhere.
The shopping cart is built from a table, with rows which only can have one text line per row. That's done by CSS. So far so good.
When I look at that website through an iframe from within my wordpress site http://www.flexkrykker.dk/?page_id=76, the shopping cart's table's rows have multiple text lines per items.
So it seems that WordPress is overruling CSS.
I've found out that there are plugins, which can help, and I've found out that there should be a little thing I should purchase to solve my problem. However, I haven't found the plugin, neither I've found a link to purchase that CSS Upgrade thing.
How in the world can I use my own css in an iframe without WordPress is intercoursing it all up for me?
