prepare for switching easily between column and classic modes
create functions to switch between modes
transform position into object constructor
correct mistake
correct mistake 2
try something else to get element width
had forgotten to specify margin right in basic mode
add smooth css transition between modes
make sure transition works but not when setting the design for the first time
correct mistake: unit missing
wait transition end before putting comments in column
no waiting for first call
remove transition listener after event has been triggered
