-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:
By varying the voltage supplied to the armature, operators can directly control the motor's speed. Field Weakening:
: Foundations of control circuit design using magnetic relays and contactors. System Maintenance
Unlike many textbooks that drown the reader in Maxwell’s equations before explaining a simple start/stop circuit, Moberg’s writing is famously pragmatic. The book originated as a set of training notes for technicians and field engineers. Consequently, the "AC and DC Motor Control" text bridges the gap between electrical theory and hands-on troubleshooting.
The text serves as a practical guide for engineers and technicians, focusing on the application of relay logic, motor control systems, and electrical code requirements in professional, "on-the-job" environments. It prioritizes real-world application over complex mathematics, requiring only a basic understanding of electrical theory. Amazon.com Key Technical Concepts
