Edit Profile Page Formatting - New Issue

I have added the following custom CSS code to facilitate a change to several fields.

#buddypress .standard-form p.description {
margin-top: -12px;
font-size: 12px !important; }

It is working perfectly, with one exception.

field_1 doesn't work. I need the margin-top to be 0px for that one field.

Can you tell me please how to code it correctly to just apply to field_1

Thank you.
