Nothing happens when I type in the CSS code

[data-section-id="63beb98de057586f4868172d"] {
    background-image:
    linear-gradient(to right, #F9A01B, #F6A821, #F4AF2D, #F1B639, #EFBD45),
    radial-gradient(circle at top left, #F9A01B, #F6A821, #F4AF2D, #F1B639, #EFBD45);
    background-size: 100% 100%;
    background-repeat: no-repeat;
    position: relative;
}
[data-section-id="63beb98de057586f4868172d"]:before {
    content: "";
    position: absolute;
    width: 100%;
    height: 100%;
    top: 0;
    left: 0;
    box-shadow: 0 0 20px 20px gold;
    opacity: 0.1;
    z-index: -1;
}

I think you need to hide section image or section default background, to this code work

Can you share link to page where you use this section? We can test code easier
