If you are referring to having the labels above the data, it is not CSS. If you are referring to the rounded corners, then that is CSS. Depending on how you created the infobox, you may not have been fully aware of what you where inserting. Did you use InfoboxBuilder or source mode? When using InfoboxBuilder, the "insert section header" option inserts the group tag. Unfortunately, it looks like you cannot select the layout type using InfoboxBuilder. Therefore, you will need to use source mode to set the layout for that section. To access source mode from the InfoboxBuilder, click the button with "[]" that should be in the lower-right corner of the editor.
