Notes
The fonts available are those on the user's device (computer, phone, tablet, etc.) or installed in their browser. If there is an exact match, that font will be used. If not, then a font from the same family will be used. For example, if you set the FontName to Helvetica Neue but that font was not available, a font from the Helvetica family would be used instead.
Sample Code
This code sets the FontName property.
Me.FontName = "Helvetica"
