@css-hooks/react NPM

Overview

Hooks add CSS features to native inline styles, enabling you to apply styles conditionally based on pseudo-classes, custom selectors, media queries, and more—all without leaving the style prop. By exploiting the hidden programmability of CSS Variables, CSS Hooks delivers a flexible CSS-in-JS experience without runtime style injection or build steps.

Feature highlights

Pseudo-classes

<button
  style={pipe(
    {
      background: "#004982",
      color: "#eeeff0",
    },
    on("&:hover", {
      background: "#1b659c",
    }),
    on("&:active", {
      background: "#9f3131",
    }),
  )}
>
  Save changes
</button>

Selectors

<label>
  <input type="checkbox" checked />
  <span
    style={pipe(
      {},
      on(":checked + &", {
        textDecoration: "line-through",
      }),
    )}
  >
    Simplify CSS architecture
  </span>
</label>
