{ display: none;} Doesn't work

I need help… I’m following a tutorial on YouTube, trying to build a restaurant website. Everything is fine until this point. I don’t understand why I can’t get display: none; to work. Is there a problem in the code?

My full HTML CSS JS:

I don’t know which one is display: none do u mean. Can you be more specific please, if not we can’t help. Maybe you can highlight the code you mean!

Ahh, you can go first @bbsmooth :blush: :blush:

Can you be a little more specific. There are several elements with display: none. Which one are you asking about? And what are you trying to do?

Ahh, I see @nurularifin83 beat me to it :slightly_smiling_face:

Sorry for not being very specific, I’ve been sitting and rechecking the code for quite a while now… I needed help with
.header .btn { display: none;}

But found a mistake in my html, I closed the element twice.


Happy to hear you solved it.
