How to horiz center (w/o columns) an image, text and button

In the picture above, I’d like to center the AppDiv contents, so that when the screen resizes all objects stay centered. I also want to add some padding and margin to “align” everything-- but I think I can handle that part.

I’ve played around with this for awhile and it doesn’t seem to work UNLESS I use columns and I’d rather not use columns unless I have to. TIA
