CSS Arrives
The CSS3 Revolution
Border-radius changed everything.
Rounded Corners
No more corner images. border-radius gave us curves.
Gradients
Glossy buttons and skeuomorphic depth — all in CSS.
Transforms
Rotation, scaling, 3D. The web learned to move.
Box Shadows
Depth without images. The flat-to-material pipeline begins.
Modern CSS
The dark mode era. Custom properties. Grid. Flex. Clean.
--custom-properties
Design tokens in pure CSS. Themes became trivial.
display: grid
Two-dimensional layouts without hacks. Tables retired.
display: flex
Centering a div finally made sense.
prefers-color-scheme
Dark mode became a first-class citizen.
The Platform
The browser is the runtime. CSS is the framework. HTML is the API.
