CSS architecture and styling
Stylesheets designed to be extended. Most CSS problems are architecture problems, not browser problems.
Styling
Chosen per project
Maintainable handover
CSS rarely fails at the level of a single rule. It fails at the level of a codebase — specificity wars, a growing list of overrides, and a point where nobody dares delete anything because they cannot tell what it affects.
The fix is structural: design tokens for colour, spacing and type; components that own their styling; and layout built with grid and flexbox so the page reflows intrinsically instead of through a ladder of breakpoints.
What we build with CSS3
Design systems shared across several products
Sites that must be responsive without a breakpoint for every screen
Rescuing a stylesheet that has become unmaintainable
Theming — dark mode, white-label or per-brand styling
Where it fits — and where it does not
Good fit when
Consistency across many pages or products
Fluid layouts that adapt without dozens of media queries
Performance-sensitive sites where less JavaScript is better
Teams that will maintain the stylesheet themselves
Consider something else when
Complex animation sequencing is often clearer in JavaScript
Very small one-page sites rarely need a full token system
The order a stylesheet should be built in
Each layer depends on the one before it. Building them out of order is what produces the override ladder that makes CSS feel unmanageable.
Tokens
Colour, spacing, type and radius in one place.
Reset
A predictable baseline across browsers.
Base
Document, typography and focus styles.
Layout
Containers, sections and grid primitives.
Components
Self-contained, reusable pieces.
Refinements
Breakpoints, print and forced colours.
How we work with CSS3
Design tokens
Colour, spacing, type and radius as custom properties, so the whole site retunes from one file.
Intrinsic layout
Grid and flexbox with sensible minimums, so components reflow without a breakpoint each.
Flat specificity
Shallow selectors and clear component boundaries, which is what keeps overrides from accumulating.
Motion discipline
Transitions on composited properties, and every animation gated behind prefers-reduced-motion.
Our typical CSS3 setup
| Concern | What we use |
|---|---|
| Tokens | Native CSS custom properties, no preprocessor required |
| Layout | CSS Grid and Flexbox with intrinsic sizing |
| Responsive type | Fluid clamp() scales rather than stepped breakpoints |
| Theming | Token overrides for dark mode and white-label builds |
| Motion | Composited transitions, gated on prefers-reduced-motion |
| Delivery | Layered stylesheets loaded in parallel, no import chains |
Frequently asked questions
Not necessarily. Native custom properties, grid and nesting cover most of what preprocessors were invented for. A utility framework helps large teams stay consistent; for a single well-structured site it mainly adds tooling.
Almost always deep selectors and rising specificity: each fix is an override on the last, so nothing can be removed safely. The remedy is flattening specificity and giving components clear boundaries — incremental, not a rewrite.
As few as possible. Layouts built with intrinsic sizing reflow on their own; breakpoints should handle the deliberate changes, not every screen width.

Services built with CSS3
Website Development
A website is usually the first thing a prospective customer sees. It should load quickly, say something useful and be findable.
UI/UX Design
Interfaces designed around what people are trying to accomplish, then tested with them before development starts.
Web Application Development
Applications that run in the browser, handle real workloads and hold up when several departments depend on them at once.
