It's not just width and height anymore. Understanding logical properties (margin-inline, padding-block) is essential for building internationalized, bi-directional layouts.
02Specificity Control
Mid-level developers don't use !important. They understand how to use layers (@layer) and :where() to manage specificity and avoid the 'CSS Cascade War'.
03Performance Styling
Animations should be performant. Using transforms and opacity instead of animating width/height ensures that your UI runs at a smooth 60fps on all devices.
