Great, thank you so much, but i got an another trouble:
I have followed the tutorial provided by you and achieved the desired effect, but I think it seems to have lost something.
For example, if my current page is “shop”, it should be highlighted or activated. The “shop” should be yellow(#f9bf39) at this time.
I don’t know how to describe it in detail, I hope you can understand what I mean, plase check the attackment of screenshot.

Regards
