Help with multi-column Layout for label / text inputs

I would like to format my input fields side by side with the styling of the fieldcontain ( hopefully but not required )

But it appears that the field contains forces 100% width - even if i float left and style with width=48%

The Label applies to both text boxes like this - and the texboxes are for number and decimal inputs only
