How can I set a different navigation style across my site?

I have a dynamic nav style on the homepage but want to have a solid on some / all of the other pages. How can I do this?

Many thanks! 

Hi, here's a code snippet to have solid nav style on all other pages of your site.

Solid nav style on Portfolio page:

#collection-64d778ba0e10926886eccde6 header#header {
    background-color: #000 !important;
}

Solid nav style on FAQ page:

#collection-63ff2594a143f02a795d9f42 header#header {
    background-color: #000 !important;
}

Solid nav style on Contact page: 

#collection-64039a3b841d133068532167 header#header {
    background-color: #000 !important;
}

Just add the code for the pages you want the nav style to be solid. Thanks!

Awesome, thanks a million 🙏
