OpenersNotesSection(Spacer1)Details

A fraction can be created using (Key1[ctrl, /]) or (MenuGrayLink[Insert, paclet:guide/InsertMenu]) ▶ (MenuGrayLink[Typesetting, paclet:ref/menuitem/Typesetting]) ▶ Fraction menu item.

With the default setting (RefLink[FractionLine, paclet:ref/FractionLine])->(RefLink[Automatic, paclet:ref/Automatic]), the fraction line has a thickness equal to the default thickness of a line in that font. This is the thickness, for example, of lines in the hyphen (-) and underscore (_) characters.

With the setting (RefLink[FractionLine, paclet:ref/FractionLine])->None, the fraction line has zero thickness; in other words, it is invisible.

With the setting (RefLink[FractionLine, paclet:ref/FractionLine])->k, the fraction line has a thickness k times the default value.

For a selected fraction, (RefLink[FractionLine, paclet:ref/FractionLine]) is set as an option of the (RefLink[FractionBox, paclet:ref/FractionBox]) object, and applies only to the selection.
