Efforts have been made to conceal everything except the main content on this particular Facebook post
The following CSS code has been attempted without success - I would appreciate any assistance.
html body * {
display:none;
}
#contentArea {
display:block;
}
Displayed below is a screenshot of the desired outcome. https://i.sstatic.net/vY4UX.png
Using the CSS selector body *, you can hide all child elements on a webpage.
If you use #contentArea to show a specific block, the styles applied by body * will still affect both child and parent elements.
To completely hide everything else on the page, you'll need to define more specific rules in your CSS.
It's worth noting that displaying an element with a hidden parent is not possible, as previously mentioned. Surprisingly, Facebook's layout turned out to be simpler than expected - you just need to hide the header and sidebar elements if the user is not logged in.
Simply inject this CSS:
#pagelet_bluebar, #rightCol {
visibility: hidden;
}
Here is the result:

And this is the result if the user is logged in:

If you want to hide the chat sidebar, include #pagelet_sidebar in your CSS:
#pagelet_bluebar, #rightCol, #pagelet_sidebar {
visibility: hidden;
}
In conclusion, focus on hiding the main components rather than everything on the page, or utilize jQuery to target all elements except for your specific one, as suggested by @MaVRoSCy.
Big shoutout to everyone for your input - here's the ultimate mix of all the suggestions:
#leftCol, #pagelet_bluebar, #rightCol, #pagelet_bluebar {
visibility: hidden !important;
display: none !important;
}
html ._5vb_.hasLeftCol #contentCol {
border-left: initial !important;
margin-left: initial !important;
padding-left: initial !important;
padding-top: initial !important;
}
._5vb_, ._5vb_ #contentCol {
background: none !important;
}
