[Solved] How to Apply margin to web content but not when a video is in fullscreen?

hi, I would like to know how to Apply margin to web content but not when a video is in fullscreen? and keep the margin when Firefox is in fullscreen. I mean I would like to apply a margin to web content that not affect when a video is in fullscreen. I used this code:

:root:not([chromehidden~="toolbar"]) {
        
        /* Web content */
        & #appcontent{
            margin-inline-start: var(--my-vertical-toolbar-width) !important;
        }

        /* Sidebar + sidebar content */
        & #sidebar-box[checked="true"] {
            margin-inline-start: var(--my-vertical-toolbar-width) !important;
        }

        /* Sidebar + sidebar content + web content */
        & #sidebar-box[checked="true"] ~ #appcontent {
            margin-inline-start: 0px !important;
        }
    }

but that applies a margin when a video is in fullscreen, I tried too this code but removes the margin when Firefox is in fullscreen:

:root:not([chromehidden~="toolbar"],[sizemode="fullscreen"]) {
     ...
}

@[email protected] hi, I wanted to bother you with another question, If you use the new feature of Vertical-tabs you maybe notice that if you have the Sidebar expanded the tabs is like they stuck in some way, I'll show you this with new-tab pages but is the same with webpages: https://imgur.com/a/BbECuIp

I think this is not a behavior caused by a CSS or it is possible?
- I'm not sure if we're talking about the same thing, but the first thing I noticed from that video is that it seems as if tabs aren't closing properly. Same kind of deal happens with horizontal tabs if you unconditionally force min-width or max-width for tabs.
  
  That being said, I wouldn't put too much effort into supporting vertical tabs yet because it's constantly changing still.
  
  ooh, I notice a rare behavior when use this in horizontal tabs, so the issue is that min-max width cause problems, I understand.
  
  /* Horizontal tab size */ .tabbrowser-tab[fadein]:not([style^="max-width"]) { max-width: 200px !important; }
  
  in Vertical tabs I noticed that the property of the tab that don't close has fadein property, I tried this code to delete that empty space, but visually works but in the background the tab is still stuck.
  
  /* Important! bug fix for tabs that keep space after close them */ .tabbrowser-tab { &:not([pinned], [fadein]) { visibility: collapse !important; } }
  
  In horizontal tabs the tab is really removed only after its closing animation is done - in that case when its width reaches 0px. I have not looked what the closing transition is in vertical tabs - but it stands to reason that it might be its height. If that is the case (which again is just a guess) then you should make sure that you aren't setting min-/max-/height for tabs anywhere that then would prevent the tab from being getting to 0px height.
  
  Information that heals, thanks for all. 💙
