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"]) {
...
}
At first glance that sounds like for some reason the tab selection is super slow occasionally. The
selectedattribute on.tabbrowser-tabhappens very soon after you click the tab, but the other stuff happens and eventually the.tab-backgroundgets its selected styling. Sounds like that would sometime take several frames during which the background-color is not covered by normal selected-tab styling.You can try to replace
[selected]there with[visuallyselected]which gets added a bit later, but if there's some weird latency going on then that might still be too soon.I'll try it, hope works fine, ty. ๐
