Can't remove padding from text block on mobile

Site URL: https://www.whoisraag.com/play

I'd like the text on top (the one in blue) to have zero top padding - https://www.whoisraag.com/play

Only for the mobile version though. On desktop, it looks alright. Here's the code I'm using (Not sure why it isn't working)

@media screen and (max-width: 767px) {
    div#block-yui_3_17_2_1_1610873797494_118053 {
      padding-top: 0px;
    }}

The same code responds to padding-bottom, but not the top.
