Hi Ziyang,

While we do not currently offer dark mode and text size settings in Khan Academy, please know that we continue to add new features to improve the experience. I've passed your feedback along to the team and it will be part of our conversation as we plan the future of Khan Academy.

Additionally, I’d like to recommend you check out some apps that add this kind of "dark-mode" functionality. F.lux, for example, is specifically designed to make the colors on your computer's display adapt to the time of day.

Some more options are available here:

• Redshift - Windows, Linux, BSD
• Lightbulb - Windows
• Twilight - Android
• Iris mini - Mac, Windows, Linux
• G.lux - Mac, Windows, Linux, ChromeOS

Thank you for helping us improve Khan Academy!

Dustin
