01Overview
CSS turns structure into experience. I build responsive, maintainable styling systems with Flexbox and Grid, and scale them across teams through design systems.
02Key concepts
What anyone working with it needs to understand
- 01
Cascade & specificity
How rules win, and how to keep specificity low and predictable.
- 02
Box model
Content, padding, border, margin and box-sizing.
- 03
Flexbox & Grid
One-dimensional and two-dimensional layout, and when to use each.
- 04
Responsive design
Mobile-first, media and container queries, fluid typography.
- 05
Custom properties
CSS variables as design tokens for theming.
- 06
Animations
Transitions, keyframes and performant transform/opacity animations.
03In practice
Responsive interfaces at every company I've worked for, the Claro rebranding rollout and contributions to the Mondrian design system.
