Changing my background

I was searching through skins and I found one with fireworks in the background.

I didn't like it and I changed it BUT when I changed the theme the fireworks stayed as the background.

I tried to set a new theme, background but nothing has worked.

It'll be an image in your CSS. Right click on the background of your site and click "Copy Image Location". Then go ACP -> Disply -> Colors -> CSS Spreadsheet -> CTRL F -> Paste the image location -> Find the part that it's in and change it to your desired background image.

Hello,

Please navigate to Admin CP > Display > Colors > CSS
Add this code there and submit...

Code:

body {
background : url(BACKGROUND IMAGE URL HERE) repeat;
}
