How do you hide the navigation on a landing page in mojave

I am trying to create a landing page in mojave with just an image and an enter button. How can I hide the navigation?

@jenniewinhall Each Page will have diferent ID. First you need to find ID of Landing Page. See how to: https://beaverhero.com/squarespace-how-to/#HowtoFindPageID

Add this code to Home > Design > Custom CSS. Replace body#...d3fb with your landing page ID.

body#collection-56e070e59f726659e9f1d3fb .Header-nav {
   display: none !important;
}

Thankyou @tuanphan!

I have tried hiding the .Header-nav both through the page header code injection and in Custom CSS with the collection ID as you suggest.

With both it works at the backend, but when I view the site as a user it doesn't work until the page is refreshed. And the navigation is hidden on the other pages until they are refreshed.

Is there something else I should try?

@jenniewinhall Can you share site url to me check code?

I just rebuilt the page from scratch and added the code above in custom CSS again - and now it looks like like it is working! hankyou so much @tuanphan!

My next question is whether there is a way to hide the landing page menu item in the navigation on the rest of the pages. Grateful for tips.

Many thanks!

@jenniewinhall What is "landing page item" in Navigation? I didn't see
