Answer 1

将此添加到 </body> 的底部。在这种情况下是 inner_categories 容器。

    <script>
        var item = document.getElementById("inner_categories");
        window.addEventListener("wheel", function (e) {
            if (e.deltaY > 0) item.scrollLeft += 100;
            else item.scrollLeft -= 100;
        });
    </script>
