Idk how much this helps, but whenever I want to figure out how something works in CSS I hold Ctrl + Shift + J on someone's page and look through the code.
...
here's a config I found on someone's page.
.player::before
content: "";
display: block;
position: relative;
width: calc(50% -20px);
height: 335px;
max-width: 390px;
background-position: 0 0;
background-size: 100% 100%;
background-image: url();
object-fit: cover;
AAAAA TYSM!
