Base UI is a library of headless ('unstyled') React components and low-level hooks. You gain complete control over your app's CSS and accessibility features.

export function getMidpoint(element, vertical) {
  const rect = element.getBoundingClientRect();
  return vertical ? (rect.top + rect.bottom) / 2 : (rect.left + rect.right) / 2;
}
