Styling

A comprehensive guide to CSS styling approaches for React, Angular, and Vue applications. Covers the CSS scoping problem and solutions including BEM naming conventions, utility classes with Tailwind (including installation and compilation behavior), CSS Modules for automatic scoping, Sass/SCSS features like compile-time variables, functions, loops, and mixins, runtime CSS-in-JS with Emotion (including performance concerns like FOUC and SSR issues), and compiled CSS-in-JS with PandaCSS as a performance-friendly alternative. Each approach includes setup instructions and code examples for all three frameworks.
