-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.”

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.

In an environment where academic integrity is the highest currency, the mere suggestion of cheating can end a future career before it begins. Blackmailers use this "SE" leverage to demand escalating payments or further illicit actions, trapping the student in a cycle of debt and fear. The v10 Defense

The effects of blackmail on education are multifaceted and devastating:
