**Hello there! I hope in times like these, you’re safe.**  
I have been struggling to achieve persistence dark mode while navigating two pages. The page contents turn back to default color while from navigating from pages. I’m an absolute novice/beginner in javascript. This is my two page sample html [gist.github.com/samiuljoy](https://gist.github.com/samiuljoy/f76c8944f8b7b3eecc57cf86ae4ad0ef)  
Could you please help me to add persistent dark mode among these two html pages.  
Greatly appreciate this website, keep up the good work c:

I would suggest `localStorqge` over `sessionStorage`, for `localStorage` persists your selection across multiple browser instances: [https://www.kirupa.com/things\_to\_do\_with\_data/web\_storage.htm](https://www.kirupa.com/things_to_do_with_data/web_storage.htm)

I will try to provide a longer answer this evening, but combining a storage solution with a JS check that sets a dark mode class at the root HTML layer might do the trick.
