-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:
The domain "math.lessons.lol" represents a fascinating microcosm within the broader digital educational landscape. At first glance, the URL suggests a potential repository of informal tutorials or a meme-centric approach to pedagogy. However, a deeper investigation reveals that this specific domain serves as a primary gateway to one of the most significant phenomena in modern secondary education: the rise of "Niche" online academies, specifically the organization known as "Niche" (formerly associated with SAT/ACT preparation platforms). This paper explores the duality of "math.lessons.lol" as both a technological artifact—a redirect bridge utilizing the popular ".lol" top-level domain for marketing—and a symbol of the shifting paradigm in mathematics education. We examine the platform’s pedagogical structure, its role in the "democratization of elite test prep," the controversies surrounding intellectual property in education, and the implications of casual domain branding in academic contexts.
: Popular blogs like Math With Bad Drawings use stick figures and humor to tackle everything from basic geometry to current events.
Most math sites have a sterile FAQ. Math.lessons.lol has a confessional booth. Students anonymously submit their most embarrassing math confessions, and the community responds with support and laughter. "I thought the number 0 was a letter until 9th grade." becomes a teaching moment.
