How to remove top menu bar

Hi,
You can hide it using the following CSS code:

#top-navigation {
    display: none;
}

Use custom CSS plugin to put the code in above

Hello I have searched high and low on every single forum and can’t seem to find any way to remove the very top menu bar on my wordpress site. This is the link: https://markmaker.ca/index.php/social-media/

I want to remove the menu bar on only a few pages. I added multiple custom CSS plugins and tried tons of different codes.

The menu bar I am referring to is the one that says: home, work with us, FAQ….

Please help!
