Respected sir/ma'am,
As per my idea in this project , Normally most of browser has contains dark & white mode , it will achieve through the some manual configuration in settings. And most of people, there didn't spending time to configure a settings based on day & night.
My approach:-
1. If we add automatic theme changing mode option in settings with respect of server time. And it will helpful for some kids and lazy people better to avoid a "eye issue".
2. If we add brightness changing mode button icon in window screen. It will make more easy to access it for manual changer.
Advantage:
If this concepts were achieved means, it give some user friend experience to users
