Store Design

I want to change the Color of my sale button and I have succeeded in it but it’s only changing on my laptop screen, not on my smartphone.
Please, someone can resolve this issue for me
Thanks

#SiteNav > li:nth-child(1) > a > span {
font-weight: bold;
color: red;
}

You likely have a different navigation for mobile and desktop, can you share a link?
