All I want is the simplest of codes to do this. I've tried like seven different codes from various websites, but none of them seem to work. Not sure what i'm doing wrong, or if Subeta uses something different, or what.

can you try going to this link and adding this to your profile (replacing 000000 with the color you want of course)?

Thank you so much for taking time to help me!

okay I tried adding <style>body {background-color: ;}</style> but nothing changed. I also tried taking out the spaces to make it <style>body{background-color:;}</style> Waited like 10 minutes to make sure it wasn't the cache being slow, but it's still white as anything.

Do I need some other code added to it to make it work? This is literally the only thing in the profile text box.

ohh i see why! go to this, click on "add content", then the "profile" button

oooh, that worked! Thank you so much! So I just need to go there and add it whenever i change something from the dashboard?

in fact, you don't have to add it every time. as long as you have that section on your profile, whatever css you put in or change will appear :)

Thanks!
