Hide Navigation on an Unlinked Page (i.e. page is public but does not appear on main site navigation bar)

Site URL: https://concure.squarespace.com/learn-more-about-concure-oncology

Hi,

I created an unlinked page that I would like to use as a landing page. However, I do not want users to see the navigation bar associated with my main site. Currently, this page has a logo and would like to keep it as is on the top banner. How can I just remove the navigation bar through a page header code injection? For reference, I am using the Bedford template. 

Thank you in advance. 

I see you fixed problem?

For future users, use this code (add to Page Settings > Advanced > Header)

<style>
  #headerNav {
    display: none!important;
}
</style>

@tuanphanThat code injection into the header of my landing site does not get rid of the navigation tab. Below is what I used to maintain my logo and get rid of the navigation:

<style>
#headerNav{display:none!important}
  @media only screen and (max-width: 640px){
     .mobile-nav-toggle-label, .fixed-nav-toggle-label,.top-bar,.middle-bar,.bottom-bar{display:none!important;}}
</style>
