Emotion

ELI5 — The Vibe Check

Emotion is CSS-in-JS that gives you two flavors: the styled-components-like syntax AND a css prop for inline styles. It's like a Swiss Army knife for styling - pick whichever approach fits the moment. MUI uses it under the hood, so you might already be using it.

Real Talk

Emotion is a performant CSS-in-JS library offering both a styled API (similar to styled-components) and a css prop for inline style objects. It supports server-side rendering, automatic vendor prefixing, and source maps, and serves as the styling engine for Material UI.
