Show vertical scrollbars?
Specify how to handle an element that has too much text to fit inside its determined height.
Use one of these keywords:
|The text simply overflows the bottom boundary and overruns whatever else is there.
|The text is clipped at the bottom boundary and is not visible.
|A vertical scrollbar is always visible, but is only enabled if the text is too high to fit.
|If the text fits, no scrollbar is shown. If the text is too high to fit, the scrollbar is shown and enabled.
