-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:
| Author | Strength | Weakness | Repack Value | | --- | --- | --- | --- | | | Direct exam pattern, Tamil Nadu specific, many solved problems. | Theory is dry; problems are mixed with unsolved exercises. | High – Separating solved from unsolved is a chore. | | B.S. Grewal | Highly detailed theory. | Too bulky (1,200+ pages); not semester-specific. | Low – Grewal formulas are better as reference. | | Kreyszig | Advanced mathematical rigor. | Overkill for Indian university exams. | None – students don’t repack Kreyszig. | | G. Haribaskaran | Excellent question bank. | Fewer step-by-step solutions. | Medium – Haribaskaran + Singaravelu = Power combo. |
by Dr. A. Singaravelu is a staple textbook for third-semester engineering students, particularly within the Anna University system. This "repack" typically refers to a curated collection of solved problems and university question banks designed for rapid exam preparation. 1. Core Subject Modules
This phrase reveals a deep student need: not just a textbook, but a comprehensive, organized, easy-to-digest collection of fully solved problems. In this long-form article, we will break down why this resource is critical, the anatomy of a "repack," how to use it ethically, and where to find legitimate academic support.
: The "repack" likely prioritizes high-weightage topics such as singular solutions, Laplace transforms, and complex variables that frequently appear in standard engineering exams.
