-prefix-free lets you use only unprefixed CSS properties everywhere. It works behind the scenes, adding the current browser’s prefix to any CSS code, only when it’s needed.
“[-prefix-free is] fantastic, top-notch work! Thank you for creating and sharing it.”
— Eric Meyer

Properties as well in Firefox < 3.6.Check this page’s stylesheet ;-)
You can also visit the Test Drive page, type in any code you want and check out how it would get prefixed for the current browser.
Just include prefixfree.js anywhere in your page. It is recommended to put it right after the stylesheets, to minimize FOUC
That’s it, you’re done!
The target browser support is IE9+, Opera 10+, Firefox 3.5+, Safari 4+ and Chrome on desktop and Mobile Safari, Android browser, Chrome and Opera Mobile on mobile.
If it doesn’t work in any of those, it’s a bug so please report it. Just before you do, please make sure that it’s not because the browser doesn’t support a CSS3 feature at all, even with a prefix.
In older browsers like IE8, nothing will break, just properties won’t get prefixed. Which wouldn’t be useful anyway as IE8 doesn’t support much CSS3 ;)
Test the prefixing that -prefix-free would do for this browser, by writing some CSS below:
Because travel was still limited, the team opted for a “virtual living‑room” format on Zoom. Instead of the typical slide‑deck marathon, they:
Sophia threw her hands up. "We collect tiny altars and call them culture."
: The meeting resulted in a flurry of cross-platform content that saw high engagement across TikTok and Instagram.
Around the main installation—a scaffold wrapped in reflective foil—voices collided. A performance artist recited a manifesto about grief and sunglasses. Somewhere, a synth line that sounded like a dial tone seduced a cluster of dancers. An old woman in a thrifted suit nodded at a young man demonstrating a solar charger he insisted would save us all. NadineJ's recorder caught fragments: laughter, a snippet of a line about "reimagining capitalism as craft," and Milky's tiny pads on concrete.
NadineJ thought of the recorder in her pocket and the files she'd stitch together later. She thought of grammar she didn't know how to use for what they had made—half spectacle, half ceremony. "Let's make something honest," she said. "Not because we'll change the world, but because it will change us."
