I'm not super great at coding, never have been. That being said I wanted to know if there was a way to place a background image on the user profile while still using the 'colored standards' the site gives you? Like putting a flower background on the 'Marsh' profile and so on? And if so, can someone tell me how?? Thank you!

i think this is what you want?

go to profile preferences and copy this code into that box: html {background-image: url('https://website.com/image.jpg');}

replace the url in the single quotes with the image url of your choice.
