网页亮色和暗色切换

An alternative implementation of the dark mode that applies a spotlight effect to the entire page when the Dark Mode is activated.

Light-on-dark color scheme, also called black mode, dark mode, dark theme or night mode, is a color scheme that uses light-colored text, icons, and graphical user interface elements on a dark background and is often discussed in terms of computer user interface design and web design. Many modern websites and operating systems offer the user an optional light-on-dark display mode.

Some users find dark mode displays more visually appealing, and they can reduce power consumption.[1] Displaying white on full brightness uses roughly six times as much power as pure black on a 2016 Google Pixel, which has an OLED display.[2] In addition, stains on a screen's surface appear less visible.

Displays with reduced blue light may improve sleep quality
