Does anyone know how to get rid of the grey box in Manipulate plots? I find that they look clunky and would look much cleaner without the box, but I am very new to the software so I don't know how I would go about that. To clarify, I am talking about the box containing the plot and slider not the plot itself.
Here is my code:
Manipulate[Plot[Sin[x (1 + a x)], {x, 0, 6}], {a, 0, 2}]
Any help would be greatly appreciated, thanks!
