I want to have dark mode for guidebooks.

Aesthetic Appeal:
Many users simply prefer the sleek, modern look of dark mode. It can make apps and websites feel more stylish or sophisticated.

Reduces Eye Strain:
Dark mode emits less bright light, which can make reading on screens more comfortable, especially in low-light environments or at night.

Improves Focus:
A darker interface can reduce visual distractions, helping users concentrate on the content rather than the bright interface elements.

Accessibility Benefits:
For some users with visual impairments or light sensitivity, dark mode can make text easier to read and interfaces more comfortable to navigate.
