Display Tagline on Mobile?

Site URL: http://ratherdesign.com

This code below worked for my one of my client's sites, but it's not working for my own site.
Please help?

/*
@media (max-width:360px) {
  .hide-tagline .site-branding .site-tagline .hide-tagline .site-branding .site-tagline {
    left: 0;
    visibility: visible;
    top: 60px;
    font-size: 11px !important;
    right: 0;
    margin: 0 auto;
    text-align: center;
}
 }

*/
.hide-tagline .site-branding .site-tagline{
  
  visibility: visible !important;
  position: static !important;
      font-size: 10px !important;
      //text-align: center;
  //padding-right: 0 !important;
}

Can you check site url?
