Looking at the bright white pages is hard job for guys seeing web pages long time(including developers) because of eyes get tired so easily.
Wanna share some tips to avoid this, write this guide.
There’s 2 steps for make whole chrome pages to black background.
1. Enable ‘Force Dark Mode for Web Contents’
Go to ‘chrome://flags’ for setting it.
Image below shows the way to set force dark mode.
Then you can see pages changed like below. Changed to black theme except for website bars.
If you wanna change whole color including website bars, you can try next step.
2. Apply dark themes in chrome web store.
Go to https://chrome.google.com/webstore/
From here you can search many dark themes. I chose ‘just black’ theme
Here shows the difference before applying dark theme and after.
