text tool and paint bucket

Ji @jonathan_5481   Do you know how to use layers and masks?  You must at least have the text on its own layer.

Experienced PS users will rarely use the Paint Bucket tool, but rather fill a layer or selection using Alt Backspace.

Note below that the white frame is at the top of the layer stack, and the blue rectangle second from from bottom.  The blue overlaps the white frame ensuring no gaps.  The characters and other content are all on separate layers.  This means you can move and resize the the frame contents without worrying about the blue background.

Note that I have linked the talk bubble and text layer.  What I would normally do is select both layers and combine them in a Smart Object, but for the sake of this post, it's easier to see what's going on with them linked.
