Page Settings is where you can make changes to the settings of a specific page on your website.
The Basic tab is where you can change the name of your page and what it is named in the navbar. The two fields do not necessarily need to match.
From the Navbar Settings tab, you can set to have the name of the page appear in the navbar menu and if you want to show the navbar on this page.
Simple check or uncheck the boxes you want and click the Save Changes button. The settings here always default to both showing the page link in the navbar and showing the navbar on the page.
In the SEO Metadata tab, this is where you would enter page specific SEO information.
Page Description: if there is text entered here, it will override the description entered on the Homepage.
Page Keywords: if there is text entered here, it will override the description entered on the Homepage.
The Open Graph tab enables any site/page to have data added to social platforms.
For example, Facebook will take this information and allow it to have the same functionality as if it was a part of the Facebook application.
The CSS included in this tab will only be included on that particular page, not site wide. Only add/modify if you know CSS, as doing so will change the look of the site and have the possibility of breaking parts of your site.
