The options that have been assigned to give this floatbox its distinctive appearance are.....
'boxBackgroundImage', 'contentCornerRadius', 'padding', 'width', 'minBoxWidth', 'innerBorder', 'outerBorder', 'colorTheme', 'contentBackgroundColor', 'captionPos', and 'controlsPos'.

When opening a new floatbox, the 'sameBox' option can be set to take over and replace the content in an existing floatbox.....
sameBox : true

Without the sameBox option set, a floatbox link will open a new floatbox in the way we've all come to know and love.....
sameBox : false
