> In React, inline styles aren't strings. They are JavaScript objects. We use camelCase instead of kebab-case for property names.

The React Styling Paradigm

En React, el estilo no es un simple atributo de texto. Es un **estado del sistema**. Tenemos dos caminos principales:

1. Inline Styles (The Object Way)

A diferencia de HTML puro donde haces `style="color: red"`, en React pasas un objeto. Esto permite inyectar variables de JavaScript directamente en el diseño.

const dynamicColor = isError ? 'red' : 'green';
<div style={{ color: dynamicColor, padding: '10px' }} />

2. Class Styles (The Architecture Way)

Utilizamos `className`. Es la forma preferida para mantener el performance y la separación de conceptos. Permite aprovechar todo el poder de CSS (media queries, pseudo-clases) que los Inline Styles no pueden manejar fácilmente.

Glossary: React UI Engineering

camelCase Styling

Converting CSS properties like 'background-color' to 'backgroundColor' for JS objects.

className

The JSX attribute used to specify a CSS class. Replaces the standard 'class' attribute.

Conditional Rendering

Using ternary operators or logical AND to switch styles based on state.

CSS-in-JS

A pattern where CSS is composed using JavaScript instead of external files.
