Great usage of CSS Custom Properties in combination with
calc() by Steve Gardner to cater for users who have
prefers-reduced-motion set to
CSS variables (custom properties) makes supporting reduced motion settings super easy. There is little excuse to not too.

0 it basically behaves like a binary condition for a CSS calculation. Simple and effective 🙂
(Personally I’d set it to either
1 – and not
0.5. That way the math is kept easy and it becomes a true binary toggle)
