About

Folder Hover is a lightweight CSS component that recreates the tactile, satisfying feeling of a folder opening — triggered entirely by :hover. It's built for developers who want a polished detail without pulling in an animation library or a single line of JavaScript.

Drop it into a file manager UI, a dashboard, a portfolio, or a landing page — anywhere a small moment of delight belongs.

Features

🎬 Smooth Motion Carefully tuned easing curves and timing make the folder open and close without a hint of jank.	🪶 Zero Dependencies Pure HTML & CSS. No build step, no npm install, no framework required.
⚙️ Fully Customizable Colors, speed, sizing, and spacing are all exposed as CSS variables.	📱 Responsive by Default Scales cleanly across breakpoints — from mobile to widescreen.
🧩 Beginner-Friendly Code Clean, commented markup and styles — easy to read, easy to extend.	⚡ Instant Load A few KB of CSS. No render-blocking scripts, no layout shift.

Usage

Every visual property is controlled through CSS custom properties defined at the top of style.css. Override them in your own stylesheet, or edit them directly:

:root {
  --folder-color: #4a90e2;      /* primary folder color */
  --folder-accent: #f5a623;     /* inner tab / accent color */
  --animation-speed: 0.35s;     /* open/close transition duration */
  --animation-easing: ease-in-out;
  --folder-size: 120px;         /* base folder width */
  --folder-spacing: 24px;       /* gap between multiple folders */
}

Variable	Controls	Default
