Styling Best Practices for Headless UI

1. Introduction

Headless UI refers to a set of components that provide functionality without enforcing a specific style. This allows developers to implement their design systems while maintaining accessibility, responsiveness, and performance.

3. Styling Best Practices

3.1. Consistent Design System

Establish a design system that outlines fonts, colors, spacing, and component styles. This system serves as a reference for developers and designers.

3.2. CSS-in-JS

Utilize CSS-in-JS libraries (e.g., styled-components, Emotion) for scoped styles that can easily adapt to component states.

import styled from 'styled-components';

const Button = styled.button`
    background: #007bff;
    color: white;
    padding: 10px 20px;
    border-radius: 5px;

    &:hover {
        background: #0056b3;
    }
`;
            

3.3. Utility-First CSS

Consider using utility-first CSS frameworks (like Tailwind CSS) that promote building designs using utility classes.

    Hello World

            

3.4. Responsive Design

Ensure your styles are responsive. Use media queries or responsive utility classes to adapt to different screen sizes.

@media (max-width: 768px) {
    .container {
        padding: 10px;
    }
}
            

3.5. Accessibility

Always consider accessibility in your styles. Use semantic HTML, ensure sufficient color contrast, and provide focus styles.
