Spacing between Label and Field when aligned left

I would like to align my Month, Day and Year fields to put the label on the left but when I do that there is a huge gap between the label and it's field.   How can I specify a specific spacing for each field?

When Reviewing your form I noticed that you had hidden the date field and placed 3 other fields to enter the date. If you would like to use the date field and reduce the spacing between the label and text field, you can inject the following CSS code.
