You can change the text attributes (like font, size, color, and style) for data in text, number, date, time, and timestamp
fields. You can also change the paragraph alignment, margins, and line spacing.
Important You can change text attributes for field data in both
Browse mode and
Layout mode. Layout mode formatting is specific to a particular layout. Browse mode formatting is stored with the data and applies in any
layout that displays the field. For more information on whether to format data in Browse mode or Layout mode, see
Formatting text.
If you don’t see the formatting bar, click
Formatting 
in the
layout bar.
