roblox css help

Evan The d0m0

hi, I was just wondering what to type in the CSS box. I was trying to make a Roblox background but I didn't know what to put in the CSS box. I'd appreciate it if anyone would tell me what to put (my first time)

Give body the background. Then change another background color to transparent.
like this:
body{
background-image: url(https://cdn.pixabay.com/photo/2015/04/23/22/00/tree-736885__340.jpg)!important;
background-repeat: no-repeat!important;
background-size: cover!important;
}
*{
background-color: transparent!important;
}
