Changes to site title font not working on mobile devices

Hi Zed,

I have used custom CSS on my website to alter the font and size of my site title:

#site-title span a { font-size: 110px;}
#site-title span a {font-family: “Tw Cen MT Condensed Extra Bold”, “Tw Cen MT Condensed Bold”, “Futura Std Condensed ExtraBold”, “Futura Std ExtraBold”, “Poppins:Bold”, sans-serif }

@media (max-width: 1020px) {
#site-title
body #site-title span a {
@import
url(https://fonts.googleapis.com/css?family=Poppins:bold&text=”Little Bo Beats”);
font-size: 36px;
line-height: 36px;
font-family: “Tw Cen MT Condensed Extra Bold”, “Tw Cen MT Condensed Bold”, “Futura Std Condensed ExtraBold”, “Futura Std ExtraBold”, “Poppins:Bold”, sans-serif
} }

It is not working when I look at it on my tablet or phone however!

I’ve tried a couple of plug-ins plus many hours of fiddling but nothing is working.

Any help will be greatly appreciated.
