EmailMeForm allows you to link an external CSS file to further customize your form.
You can use the external CSS file for things that are not handled by the Theme Builder (i.e. absolute positioning, margins, opacity, etc).
To do this:
1. Mouse over your form, and then select "Options". Click on the drop-down for "Theme", then choose an existing theme or create a new one.
2. Click "Advanced".
3. Enter the link to your CSS file then click "Apply".
4. Click "Save This Theme" then apply the theme in your form in the Form Manager.
