i'm not actually super experienced with profile coding, so this is copied from a user in the discord about the general selectors:

for the background and stuff it's just body like usual

for the navigation bar at the top of the page you can use .toolbar, and to change the border for it you can use .toolbar, .toolbar .button by changing the border properties like this .toolbar, .toolbar .button { border-width: 2px; border-color: blue; }

for the main profile part you can use .card:not(#description), #description is another card which holds the written bio

for the title that shows your username above the main part you can use h1 or h1.no-margin they'll both affect the same thing, i just used h1.no-margin because it's more specific

for the info/statistics area you can use #stats-or-info, and for the actual drop-down menus you can use #stats-or-info details

for the "level: member/staff" part you can style the member/staff thing with .chip.badge

for the footer stuff at the very bottom of the page with the dashboard and stuff it's .__footernav

you can style buttons like the follow button with button

the thin dividers like the one above the footernav and below the list is hr

all the markdown selectors are the same as normal pastes
