-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:
sound, like a secret being whispered. It felt like a stranger in his bed. He woke up with a stiff neck, resentful of Maya’s "art." Week 2: The Softening
"Is she...?" She approached it tentatively. She touched the spot where the stain had been. "She's smooth. No residue."
No morning frizz. No pillow creases on my face. The v10 extra quality material actually lives up to the hype. Sis caught me sniffing the pillowcase (don’t judge — it smells clean longer!).
Her cat, Mochi, decided to knead the v10 like bread dough. Usually, cat claws pull threads. The v10’s weave density is so high that Mochi’s claws slid off. The cat looked annoyed. Clara looked victorious.
Day 30. I’ve reached peak relaxation. I sent my sister a selfie—no filters, no bedhead. She replied, "The v10 worked. You don't look like a swamp creature anymore." It’s the best backhanded gift I’ve ever received. I’m never going back to "standard" quality again. If you want to make this story more specific, tell me:
