Most of the time when I saw people develop &quot;for Chrome&quot; (like experiments), it would use standard stuff, but it only so happens that other browsers don&#x27;t implement them [properly], yet. Or maybe I&#x27;m just awfully pedantic, but whenever I make stuff I tend to make it as close to the standard as possible, and fall back to vendor-specific stuff only when necessary (and usually try to cover all the major browsers).<p>Also, aren&#x27;t most the Chrome-specific things disabled unless the app runs as an extension to discourage this type of chrome-only behaviour? I can&#x27;t test&#x2F;verify now, since I&#x27;m on my phone. This excludes CSS prefixes, since those are rarely needed these days anyway.
