How do I link to specific section on another page?

Sure @Marcel, this should work (not tested though):

<script>
function smoothScrollTo(element, duration = 1200, offset = 100) {
    const targetPosition = element.getBoundingClientRect().top - offset;
    const startPosition = window.pageYOffset;
    const distance = targetPosition - startPosition;
    let startTime = null;

    function animation(currentTime) {
        if (startTime === null) startTime = currentTime;
        const timeElapsed = currentTime - startTime;
        const ease = easeInOutCubic(timeElapsed, startPosition, distance, duration);
        window.scrollTo(0, ease);
        if (timeElapsed < duration) requestAnimationFrame(animation);
    }

    function easeInOutCubic(t, b, c, d) {
        t /= d / 2;
        if (t < 1) return c / 2 * t * t * t + b;
        t -= 2;
        return c / 2 * (t * t * t + 2) + b;
    }

    requestAnimationFrame(animation);
}

window.addEventListener('load', function() {
    var hash = window.location.hash;
    if (hash) {
        var element = document.querySelector(hash);
        if (element) {
            smoothScrollTo(element);
        }
    }
});
</script>
