Why Are 3D Transforms in Firefox Jagged, and How Can I Fix It?

CSS Transforms and Jagged Edges: A Firefox Dilemma

When applying 3D transforms in CSS, you might encounter unpleasantly jagged edges, especially in Firefox. Unlike its counterpart in Chrome, Firefox's backface-visibility property fails to resolve this issue.

One ingenious workaround is to add an outline attribute with a transparent color. By setting the outline to 1px solid transparent, the edges of your transformed element magically smooth out. This fix has been verified on Firefox version 10.0.2 running on Windows 7. Witness the transformation in this JSFiddle: https://jsfiddle.net/nKhr8/

If the background color of your display is not white, you can opt for a slightly different workaround. By adding a border with a color matching your background (in this case, white), you can achieve a similar anti-aliasing effect. Again, this method has been tested on Firefox version 10.0.2 on Windows 7, and produces equally crisp results. Here's the demonstration: https://jsfiddle.net/LPEfC/
