Dark Mode Everything - How to Add Dark Theme to Any Website
It is 11 PM. You are finishing up some research. You click a link and get blasted in the face by a pure white webpage so bright it could guide ships to shore. Your pupils contract to the size of a pin. Your retinas file a formal complaint.
We have all been there. And it is 2026 - this should not still be a problem.
Why Dark Mode Is Not Just a Preference
Dark mode has gone from a niche developer preference to a mainstream expectation. And for good reason:
- •Reduced eye strain - especially in low-light environments
- •Lower battery consumption - on OLED and AMOLED screens, dark pixels use less power
- •Better focus - less visual noise, more focus on content
- •Improved readability - for many people, light text on dark backgrounds is easier to read at night
- •Fewer headaches - bright screens are a known trigger for migraines and eye fatigue
The problem? Most websites still do not offer a dark mode option. Even some major sites force you into a blinding white experience with no toggle in sight.
The Solution: Force Dark Mode on Any Website
This is where browser extensions come in. Instead of waiting for every website to add dark mode (spoiler: many never will), you can take control yourself.

Dark Mode Tips and Best Practices
When to Use Dark Mode
- •Evening and night browsing - the biggest quality-of-life improvement
- •Working in dimly lit environments - offices with mood lighting, cafes, airplanes
- •Extended reading sessions - less strain over long periods
- •Presentations in dark rooms - your laptop screen will not blind the audience
When to Stick with Light Mode
- •Bright outdoor environments - light mode is actually more readable in direct sunlight
- •Color-critical work - if you are doing design or photo editing, use the site's native theme
- •Print previews - you want to see what it will actually look like on paper
> Pro tip: Use ThemeJust's per-site settings to keep light mode on design tools and dark mode on everything else. Best of both worlds.
Why a Dedicated Extension Beats Built-in Options
Chrome has an experimental "Force Dark Mode" flag, but it is rough. It inverts everything indiscriminately - including images, videos, and already-dark elements. The result is a broken-looking mess on half the sites you visit.
Dedicated extensions like ThemeJust are purpose-built for this. They understand page structure, preserve media, and apply themes intelligently. The difference is night and day (pun intended).
