-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

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:

Silas stood before his latest adversary: a single sheet of cream-colored cardstock pinned to his corkboard.
Traditionally, if you wanted a version of Minion that was slightly heavier than "Regular" but lighter than "Medium," you were out of luck. You had to choose from fixed styles.
This is where Minion’s historical roots truly shine. In metal typesetting, punchcutters modified letterforms based on the physical size of the print.

A contemporary serif with brushed curves. While more modern than Minion, Lora features a variable weight axis and offers excellent readability on digital screens.
The "Variable Concept" version serves primarily as a for Adobe’s variable font technology. Unlike static fonts with fixed weights (like "Bold" or "Light"), this font allows users to adjust properties like weight and optical size along a continuous spectrum.
The font automatically adjusts its structural details based on the point size. At smaller sizes (Caption), the counters open up, and serifs become thicker to prevent ink bleed or pixel blurring. At larger sizes (Display), the contrast sharpens, and details become remarkably elegant.
