local9ssb on "[Plugin: Formidable Forms] improve the appearance"

I should not have complete knowledge.
How can I improve the appearance of the forms?
The names appear next to the fields and to form stairs.
Can define the size of the fields on both sides?
For example, upon the name of the field and down the field to be filled. How can I change the background color of the forms?
