How to make header/nav bar width match profile width??? Closed

So the width of the header/nav bar on the top of my profile (the one with the FriendRewind logo) and the width of the rest of my profile used to match, but just recently I noticed it broke and doesn't anymore? Its width now appears shorter than the rest of my profile. I've tried a couple different things in the coding to try and adjust the width (e.g. "width", "max-width", etc.) but nothing I do seems to work and if it does, the header ends up off-centered. I'm sure there's probably a super simple way to fix it but since I'm not really the best at coding, I can't figure it out. 😅

Here's a picture of my page so you can see what I'm talking about, and also a picture of the current coding I'm using for the header/nav bar. (Hopefully the pictures actually work):

Never mind, I finally fixed it! 😅

I realized I was using "container" instead of ".master-container" for the coding for the main part of my profile, and also added "!important" at the end of the width coding which seemed to fix the problem. (I suck at explaining but hopefully that makes sense? lol 💀)

In case anyone else is having the same problem that I did, here's the code I'm using now (also changed the coding for the links at the top of the page from ".myspace header .main-nav-wrapper" to "nav .links" since I think the other code might have been from my SpaceHey layout 😅; but it did work on here, too!):
