Let's say I scroll the page to the end, after I press the menu button and the scrolling goes to the beginning, how to avoid that the scrolling remains in place after pressing the button?

Answer 1

Replace with Scroll scrolls to the beginning because of the anchor in the link <a href="#" class="menu-link">
