javascript - 使用 HREF 滚动按钮或修改 按钮链接的解决方案

Question

我有 5 个按钮，我想用它们滚动到部分

第一次我制作按钮，我用 css 自定义按钮，然后当我尝试制作一个滚动时，我遇到了问题，dosent 工作

我尝试使用链接，问题是在 css 上设置按钮效果不佳，文本在左上角

我现在尝试在 JS 上使用 CSS 滚动缓慢？或带#link 的 HTML

谢谢

HTML(我为您制作的许多版本的按钮仅用于堡垒测试)

<section id="jour">
      <div class="container20">
        <a  href="#Dimanche" class="btn1">Dimanche</a>
        <button onclick="window.location.href='#Lundi'"class="btn1">Lundi</br><b>13</b></button>
        <button onclick="window.location.href='#Mardi'"class="btn1">Mardi</br><b>12</b></button>
        <button onclick="scrollTo.location.href='#Mercredi'"class="btn1">Mercredi</br><b>13</b></button>
        <button onclick="scrollTo.location.href='#Jeudi'"class="btn1">Jeudi</br><b>14</b></button>
        <button class="btn1">Dimanche</br><b>12</b></button>
      </div>
    </section>

CSS:

 .container20 {
  display: flex;
  justify-content: center;
 }


.btn1 {
  display: block;
  height: 80px;
  width: 80px;
  color : #262552;
  font-family: "Montserrat", sans-serif;
  font-weight: 900;
  font-size: 12px;
  letter-spacing: 0.6px;
  padding: 1px 1px;
  border-radius: 3px;
  transition: 0.3s;
  margin: 30px 1px ;
  background: #9FEDD7;
  border: 3px solid #f7ee6f;

}

#jour .btn1:hover {
  background-color:#f7ee6f;
  border: 2px solid #f7ee6f;
  color : #262552 ;
}

// Cache selectors
var lastId,
    topMenu = $("#top-menu"),
    topMenuHeight = topMenu.outerHeight()+15,
    // All list items
    menuItems = topMenu.find("a"),
    // Anchors corresponding to menu items
    scrollItems = menuItems.map(function(){
      var item = $($(this).attr("href"));
      if (item.length) { return item; }
    });

// Bind click handler to menu items
// so we can get a fancy scroll animation
menuItems.click(function(e){
  var href = $(this).attr("href"),
      offsetTop = href === "#" ? 0 : $(href).offset().top-topMenuHeight+1;
  $('html, body').stop().animate({ 
      scrollTop: offsetTop
  }, 300);
  e.preventDefault();
});

// Bind to scroll
$(window).scroll(function(){
   // Get container scroll position
   var fromTop = $(this).scrollTop()+topMenuHeight;
   
   // Get id of current scroll item
   var cur = scrollItems.map(function(){
     if ($(this).offset().top < fromTop)
       return this;
   });
   // Get the id of the current element
   cur = cur[cur.length-1];
   var id = cur && cur.length ? cur[0].id : "";
   
   if (lastId !== id) {
       lastId = id;
       // Set/remove active class
       menuItems
         .parent().removeClass("active")
         .end().filter("[href='#"+id+"']").parent().addClass("active");
   }
