I understand how to add the pages through the widgets and how to create new ones through WordPress. I saw a lot of posts about changing the CSS to establish the colors for the new pages. I just don’t understand where to put this CSS code. I found the editor but when i copy and pasted the code in the other post, nothing changed.
the website in question is derekharmanli.com
Currently there is only one extra page. But I want to add another (8 pages total).
Additionally, after I added the 7th page, my Contact page has this weird white box around the map that only appears on desktop (not on mobile). It was working perfectly before that.
