I get that. sorry if i didn't make myself clear.
I was more wondring about
am familiar w/localhost from using xampp, I was looking at this code and to my knowledge you can't use css to access the "localhost" or itmes outside of the html/php page is styling.
That is where my confusion comes in.
but yes will have to check out the buttons & hover styles.
It just looks to me like a piece of corrupted code where you have joined a local url with a media query or maybe a corrupted import statement that has just been replicated and copied. Or someone just copied and pasted badly. Or badly constructed php that is outputting a broken segment. Either way it's not css and shouldn't be there.:)
If you keep a revision history you could step back and see from which point the code has been added and see where it all started to go wrong.
