Auto Theme Detection
In today’s digital landscape, users expect websites to feel intuitive, modern, and personal. One of the simplest but most impactful ways to deliver on that expectation is by supporting system theme detection—letting your site automatically follow the user’s device or browser preference for Light or Dark mode.
Why System Detection (“Auto” Theme) Is Now Standard
Gone are the days when Light mode was the only choice. Today, most operating systems and browsers offer a Dark mode setting, and users are getting used to sites that “just know” which mode to show. Enabling an “Auto” theme means your website adapts seamlessly to the visitor’s environment—no extra clicks or settings needed.
Not only does this improve accessibility and comfort (especially at night), but it also makes your website look and feel up-to-date, trustworthy, and user-centric.
How the ThemeSwitcher Component Auto-Detects Device/Browser Preference
The ThemeSwitcher component for Framer is built with modern UX in mind. With system detection as a core feature, it listens for the user’s system setting using the prefers-color-scheme
media query—a web standard supported in all modern browsers.
If the user has their device set to Dark mode, your Framer site will automatically appear in Dark mode. If they change to Light, your site updates instantly—no refresh required.
Real-Time Updates: Syncing with OS-Level Changes
What’s truly powerful about ThemeSwitcher is its ability to sync with real-time OS-level changes. If a user switches from Light to Dark mode (or vice versa) in their system settings, your website will detect the change and update its theme immediately. This creates a seamless, responsive experience that always feels in sync with the user’s environment.
Easy Ways to Set Up System Mode as Default
Setting up system mode as the default is effortless with ThemeSwitcher:
Add the ThemeSwitcher component to your Framer project.
Choose “Auto” as the default mode in the component settings.
Connect your custom Light and Dark frames (any design you like).
That’s it! Your site now follows the system theme out-of-the-box.
If users want to override the system setting, they can always toggle manually—their preference will be remembered everywhere.
UX Benefits for Modern Users
Instant comfort: No more squinting at a bright screen at night or struggling to read in the sun.
Personalized experience: Users feel at home, whether they love Light or Dark mode.
Zero friction: No need to set preferences on every site—your website just works.
Modern look & feel: Keeps your design current and future-proof.
Let your Framer site adapt to your users—not the other way around. With ThemeSwitcher, you can deliver a smart, responsive, and delightful experience on every page, for every visitor.
