I’d like to change the background of the page, and maybe the colors of some things. Can anyone tell me what codes I need to use, if it is possible in the first place?
That’s not what I meant. Should have been more clear the first time I suppose.

I mean I need help customizing my page theme. Like adding a picture for a background, change the colors of the tables, add a pic for a header background, etc. You can’t custom make the way your site looks without codes and scripts. I just need help with what exactly to do.
