Is there a possibility to change the CSS of the tab-title of a tab that is in focus?

Last year in May I asked this question:

Is there a possibility to change the CSS of the tab-title of a tab that is active? It is the discussion #3482.

Today I recognized that if the sidebar is visible, then two tabs have the same CSS, because two tabs are active. So, I'm looking for a selector name where I can define the CSS for the tab that is in focus. It is not notebook tab:focus label.

Thank you very much for an answer in advance.

This is what I already have:

/* design of tabs */
tab {
	padding-top:25px;
	padding-bottom:10px;
	padding-left: 35px;
}

/* design of active tabs (e.g. tab of the editor and tab of the sidebar) */
tab:checked {
	font-weight: bold;
	border-bottom: 5px solid black;
}

Please note that this is a Geany forum, it isn't a GTK CSS consulting forum, you may get a better answer elsewhere.

Its not focus, the editor is what is focussed, try all the pseudo classes listed in the list below this which is the nearest link target to it.

Thanks to the plugin Xi/Tweaks it is possible to change the CSS of the tab-title of a tab that is in focus. It works for all panels, so editor, sidebar and message window. For more information visit xiota/geany-preview#5 (comment).

To change only in the sidebar the CSS of the tab-title of a tab that has focus, visit xiota/geany-preview#5 (comment).
