Link colors in Mobile not showing, neither is Search function

I love the Nisarg theme, and I was able to change the link colors in my posts to be more like my accent colors. They show up great on a desktop (I want them to be really visible!) but on mobile, it’s just using the original, muted color for the links. I can’t even tell that they are links, and I know they’re there! I want my readers to see the links. How do I make my mobile link colors match the desktop links?

Also, is there a way to put the search function at the top of the post, and not all the way at the bottom on mobile?

thanks,
