You can determine the font, alignment, gap and position for database field labels in forms and reports (and group summary fields in reports). This can be done when you insert a new field (see Inserting a database field and Group summary fields). Alternatively, for an already existing field with a label, first select the field by clicking on it once when in Form Design Mode or Report View, then right-click and select Properties, followed by Label in the "Format Object Style" dialog.
On the Label page, follow these steps to edit a label:
Choose whether you want the label to be displayed (or not) by clicking the Show Label box on (or off).
In the Placement box you choose whether the label is to be displayed Over, Under, Before or After the field.
In the Horizontal Align box (for Over or Under) or Vertical Align box (for Before or After), choose whether to align the label Left, Center or Right, or Top, Baseline or Bottom respectively.
In the Gap box you can edit the default value to set the gap you want between the label and the field.
Click on the Font button to set a font, style, size and color for the label.
