Force two column on tablet

Site URL: https://podcastology.co

Hi, I'm hoping someone can help me force my site into two columns for tablet (501-800px), I want this to impact my entire site if possible.

I've been trying to use:

@media screen and (min-width: 501px) and (max-width: 800px) {
  #page .span-12 {
    .span-3 {
      width: 50% !important;
      float: left !important;
    }
    .span-3:nth-child(2n+1) {
      clear: left !important; }
  }
}
 

It's not working but I've got no clue why. I'd appreciate any help please. Website is podcastology.co and is 7.0 (Wells)

Many thanks in advance!
