I created Stylelint, an open-source CSS linter. It has over 100 built-in rules to help enforce error-free and modern code.
It's downloaded 18 million times a month and used worldwide by companies like Google and GitHub.
I consulted on the fluid design system for The Standard. It uses fluid typography to create an optimal reading experience for 1.4 million daily users.
I brought about effective collaboration and cost savings by bridging the gap between design and development.
I built the design system for Barnardo's. It contains principles, guidance and examples to create accessible digital products.
I extensively researched the ideal patterns and components for large content websites.
I co-created the design system for Thrift+, the UK's leading preloved clothing platform.
Through research into e-commerce best practices, the website redesign doubled the sales conversion rate.
I designed the EU Settlement Scheme: Update Your Details service for the Home Office.
I tested the service with users by building accessible prototypes in the browser using the GOV.UK Design System.
I create fluid design systems for fast, easy-to-use and accessible websites. I'm a CSS expert, but I'm also as comfortable designing and prototyping flows in Figma as I am writing code.
I have an eye for detail from working at creative agencies on award-winning projects such as Inside Abbey Road for Google Creative Lab (Webby), GEOX Amphibiox (Cannes Cyber Lion), and The Kaiser Chiefs' The Future is Medieval (D&AD Yellow Pencil).
Whether you're kicking off a new project or needing a hand with an existing one, I can create a fluid design system to help you deliver.
The following is my digital garden. It outlines how I leverage the browser to write less code or nothing at all.
I mostly design in the browser for the fewest capabilities:
Then I responsibly enhance the design to minimise the impact on:
While acknowledging the lack of control I have on the web.
I put my work in front of users early and often by:
I practise inclusive design to meet permanent, temporary or situational needs, and I use established patterns that are familiar to users.
When designing in Figma, I use features that align with the web:
To ensure everyone understands me, I:
I aim for a reading age of about 9. For technical and professional content, I aim for 12. I check the reading age of content using Hemingway.
I respect that:
I use comparison math functions to size space and elements relative to the viewport or container size.
example-component {
/**
* A font size with a:
* - minimum value of 1rem
* - central value relative to the container's inline size
* - maximum value of 2rem
*/
font-size: clamp(1rem, 0.5rem + 0.57cqi, 2rem);
/**
* A inline padding size that's either relative to the
* size of the characters within or the viewport's
* inline size.
*/
padding-inline: max(50% - 28ch, 4vi);
}I only override styles between cascade layers to minimise side effects.
I leverage the inheritance of properties and custom properties to encapsulate styling and provide flexibility.
@layer components {
/**
* The child component dictates a styling API by
* declaring what's inherited.
*
* By setting padding-inline, we signal it's unchangeable.
*/
child-component {
background-color: var(--child-background-color, white);
padding-inline: 1rem;
}
/**
* The parent component can change the child component's
* background and text color via inheritance as:
*
* - background-color is defined as a custom property
* - color inherits by default when not defined
*/
parent-component {
--child-background-color: black;
color: white;
}
}I create reusable components that look inwards so that their parent can lay them out.
I embrace the browser's default of Flow Layout then responsibly enhance with layout modules like Grid, Flex and Multicol, and use intrinsic sizing where appropriate.
/**
* The parent component controls the size, position
* and spacing between child components.
*/
parent-component {
display: grid;
gap: 1rem;
grid:
"img . content" auto
"nav nav nav" 2rem
/ max-content repeat(2, 1fr);
}I create smart components that adapt themselves based on their children.
/**
* The parent component changes its appearance depending
* on the presence of a child.
*/
parent-component {
&:has(child-component) {
border-color: red;
}
}I avoid overriding properties within components to simplify the mental model.
example-component {
/* These properties apply to all conditions. */
color: red;
container: example / inline-size;
padding-block: 2rem;
/* This property is added based on the selector. */
&:not(:first-child) {
margin-block-start: 1rem;
}
/**
* The background-color property is added based on
* non-overlapping container conditions.
*/
@container example (width <= 20em) {
background-color: blue;
}
@container example (20em < width <= 40em ) {
background-color: yellow;
}
@container example (width > 40em ) {
background-color: pink;
}
}I use perceptually uniform lightness for colour scales to ensure accessible contrast.
/**
* Both colours have the same perceptual lightness.
*/
:root {
--blue-50: oklch(50% 0.12 250deg);
--purple-50: oklch(50% 0.16 285deg);
}I layer accessibility improvements onto the browser's default styles.
@layer defaults {
/**
* Improve the browser's default focus visible styles
*/
:focus-visible {
box-shadow: 0 0 0 1px white;
outline: 2px solid black;
outline-offset: 2px;
}
}I nest pseudo-classes and at-rules, and use an explicit nesting selector for rules.
example-component {
&:focus-within {
color: orange;
}
@media (width >= 20em) {
place-items: center;
}
}I use tools to ensure my code and designs are consistent.
I enforce specific units with Stylelint:
{
"declaration-property-unit-allowed-list": {
"/^font/": ["em", "vi", "cqi"],
"letter-spacing": ["em"],
"line-height": [],
}
}And consistent numeric design tokens with my stylelint-scales plugin:
{
"scales/line-heights": [1, 1.25, 1.5]
}I use GitHub Flow for workflow and version control, and GitHub Actions for continuous integration and delivery.
I adhere to Page Experience signals, including the Web Core Vitals.
I test with Lighthouse and:
