A very short article about a very specific topic: draw 3D points on a 2D canvas!
It's not very complex, but it puzzled me for years, until C4ntelope made this handy introduction based on his own intuition and computations, and Román Cortés helped me complete these explanations and simplify the maths and the code.
(This article is based on that Twitter thread).

- Don't modify strings (
content: "...",font-family: '...') - Remove all CSS comments (ex:
/* ... */) - Remove all unnecessary spaces, tabs and line breaks (ex: around
+ > ~ ; : , ( ) { } /)- Keep spaces before
:in selectors (ex:* :before!=*:before) - Keep spaces around
+and-incalc(...)(but not in nth-child and nth-of-type)
- Keep spaces before
- Remove all unnecessary
;(ex:a{color:red;}) - Remove all unnecessary
*in CSS selectors (ex:*:before=>:before) - Remove leading and trailing zeros (ex:
0.1%, 1.0%, 0.0px) - Remove units after zero (ex:
0px 0rem 0% 0turn 0vmax 0dpi)
