-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:
: Holding a leading 28% North American market share as of 2025, Disney continues to leverage its "merchandisable franchise" strategy with Marvel, Star Wars, and Pixar.
The Titans of Entertainment: Studios and Productions Shaping 2026
: A top player in action and comedy (7% market share), Sony manages the Spider-Man , Jumanji , and Ghostbusters franchises.
Before Netflix and TikTok, there were the "Big Five." These traditional studios have survived the Great Depression, two world wars, and the collapse of the theatrical window. Today, they have transformed into media conglomerates, but their production arms remain the gold standard for popular entertainment.
Red Dead Redemption 2 (Cost $540M to make—more than any film ever made). Grand Theft Auto V (has generated over $8 billion). Why it’s popular: Rockstar productions offer immersive simulation. They build entire living worlds that players never want to leave.
