// Scroll the Furo left sidebar so the active page is centered in view.

// Furo keeps the sidebar at the top by default, so on a tall sidebar the

// current page can be off-screen. This adjusts only the sidebar's own

// scroll position (not the main window).

var box = document.querySelector(".sidebar-scroll");

var active = document.querySelector(".sidebar-tree .current-page");

}

var target = active.querySelector("a") || active;

var delta = target.getBoundingClientRect().top - box.getBoundingClientRect().top;

box.scrollTop += delta - box.clientHeight / 2 + target.clientHeight / 2;
