Why devs groan
Scroll lock, focus rings, overlay clicks, and theming across browsers—modals are a pain.
CSS‑Only Modal
Dark‑mode aware, animated, focusable, and no JS—uses the :target trick.
What this solves
CSS‑only open/close, dark mode, click‑outside to close, and page scroll lock via :has().
Limitations
No Escape‑key or focus trap without JS. Works great for simple dialogs.
