align-items: centeron the wrapper in preparation for text centering (note: by now the tab text are not center aligned since the red dot taking up some space of the wrapper)

position: absoluteto the red dot, so that it can position relatively to it’s parent element: the wrapper. And notice, since the red dot has absolute position, it will float out of the document flow, by now the only child of the wrapper will be the tab text, which will take up the whole space. Since the wrapper is centered in navigation tab, so is the text. Since the text is the only child of the wrapper, position relatively to the wrapper has the same effect as position relatively to the text itself.
