Change List Title Font Size on Mobile

Hello!

I am trying to adjust the size of my font on mobile for the list title, however I seem to have an issue with my code as it's not making any adjustments, although changes the font size without the media queery.

@media screen and (max-width:640px){
section[data-section-id="63b790ed7cc20541e7d8301c"]{
div.list-section-title p  {
  font-family: Argentine;
  font-size: 3.6rem !important
  }}}
