Learn how Polypane improves your workflow
Experimental Chromium features
Polypane is a browser for developers, so it comes with some experimental Chromium features turned on by default. This means you can use Polypane to try out upcoming features before they make their way into regular browsers!
Enabled features
Below are some highlights of the features that are enabled by default in Polypane. You can see the full list of enabled features on our page on Experimental Platform features .
Prefers-reduced-data
Prefers reduced data is a new media query that lets visitors signal they want to preserve data. You can emulate it in Polypane by going to the emulation section above a pane and toggling "prefers-reduced-data" to "reduce".
We wrote an article about what you can do with prefers-reduced-data, read that here: Creating websites with prefers-reduced-data.
Selectmenu
The <selectmenu>
element is an experiment to provide a more customizable select
element, with a stylable interface and options.
Spelling and grammar pseudo selectors
Use ::spelling-error
and ::grammar-error
to style text that the browser has flagged as containing spelling or grammar errors. Not all CSS properties are available for these styles.
View transitions on navigation
Use transition: view-transition
to animate the transition between pages (requires a meta tag)
CSS Anchor Positioning
With anchor positioning you can define the fallback rules to where popovers should open in relation to their anchor element.
CSS System Accent Color
use the systems accent color on your site.
Test features
In addition to the experimental features, Polypane also enables a number of features still in test:
- CSSLogicalOverflow
- CSSCaseSensitiveSelector
- CSSPseudoPlayingPaused
- CSSScrollSnapEvents
- CSSScrollStart
- CSSSnapChangedEvent
- CSSSnapChangingEvent
- CSSUserSelectContain
These might not be fully implemented yet, but are available for testing.
