Hi Hilary,
From version 5.4 of CM we made quite a few structural changes to the form creator HTML to make it more compliant for accessibility and to allow the styling to be more flexible and controllable via CSS.
There is some default CSS present in the base stylesheets for forms but you can supplement this with your own CSS via the User Uploaded Stylesheets.
As a starting point you can try copying and pasting the below CSS into your CSS file and then can tweak widths, colours, fonts etc to your needs.
One small thing to keep in mind though if your intranet is upgraded to CM 5.5 or above is we made a few further tweaks to the form creator HTML to allow greater control particularly with Checkbox and Radio Button Lists so the CSS might need to be tweaked again in those cases.
Cheers,
David
