Lichess layout change

Hi!
I was writing a study and then (I don't know how) the layout was suddenly changed : the panel of moves,chapter and so on ,were moved in different position. How can I replace them as they were in original?
Thanks

You rescaled the window and another CSS took effect. Make it full screen again. If necessary, reload the page.

I tried as you suggested but it doesn't work

Try restarting computer

Another possibility: Did you change the font size? Try pressing ctrl+0 to reset it to its default.

Well , I found the problem! You are right, but the problem was not the full screen, but the zoom percentage set to 110!

Thank you!
'Bye

Yes, that affects the CSS switches too. Ok.
