UNSOLVED Does the client-nojs element exist in the nodebb system?

[josef]

Hi,
In a MediaWiki system you can use a class called client-nojs. To apply CSS formatting to anyone who disables JavaScript in browser settings / using a plugin.
I tried to use this class with the same code (just for example:

.client-nojs * {
    display: none
}

This code should hide all the elements on the page for anyone who disables js.
In the MediaWiki system I tried this code it worked well, but in the Nodebb system nothing happened.)
The question is is there a parallel to this in the nodebb system?
