Can the Memo field properties be altered on Enter and On Exit to allow the user to visually see more

Options

Is it possible to change the size of a memo field (size on the screen/form) so when the user enters the field it increases the width of the field to show more rows as they type and when then exit the field it decreases it to it's original size. I am trying to make this so I don't have say 3 fields in a row and the last field is a Memo field that is 3 rows tall making the form look awkward. But rather make this a more dynamic form when the user has clicked on the field or is typing in the memo field. the property has a On Enters and On exits that allows javascript code to be used but I am not familiar with the JavaScript that would change the form property (field size) and refresh it as such during these two events.

Thanks
