Question

我只想固定navbar和sidebar，即使用户向下滚动页面也是如此。而且反应灵敏。在不更改导航栏和侧边栏的设计的情况下该如何做？有人可以使用引导程序为我解决问题吗？这是我的小提琴 https://jsfiddle.net/exyvat08/17/

<div class="d-flex" id="wrapper">
 <div class="bg-light border-right" id="sidebar-wrapper">
  <div class="sidebar-heading"><a href="#" class="navbar-left text-dark"><img class="mx-auto d-block" src="../images/logo.jpg" id="logo"></a></div>

 <div class="list-group list-group-flush">
  <a href="#" class="list-group-item list-group-item-action bg-light text-dark font-weight-bold">Dashboard</a>

  <a href="#" class="list-group-item list-group-item-action bg-light text-dark font-weight-bold">User</a>

  <a href="#" class="list-group-item list-group-item-action bg-light text-dark font-weight-bold">Supplier</a>

  <a href="#" class="list-group-item list-group-item-action bg-light text-dark font-weight-bold">Purchase Order</a>

  <a href="#" class="list-group-item list-group-item-action bg-light text-dark font-weight-bold">Reports</a>

</div>

原始设计

Answer 1

将您的 CSS 更改为以下形式：

.navbar{
    position: fixed;
    left: 0px; /* the key here is to make left and right '0px' */
    right: 0px;
    background: linear-gradient(to top right,#0084ff,#0084ff);
}
.content-container{ /* change this to be the container of your content */
    margin-top: 57px /* 57px is just the height of your navbar */
}

我已使用position fixed和width calc修复了侧边栏和导航栏

 $("#menu-toggle").click(function(e) {
   e.preventDefault();
   $("#wrapper").toggleClass("toggled");
   if (e.target.innerText == "Show Menu") {
     e.target.innerText = "Hide Menu";
   } else {
     e.target.innerText = "Show Menu";
   }
 });

body {
  height: 100%;
  overflow-x: hidden;
  font-family: sans-serif;

}

#logo {
  width: 160px;
  height: 150px;
  border-radius: 50%;
}

#page-content-wrapper {
    margin-left: 241px;
        width: calc(100% - 241px);
}

#sidebar-wrapper {
  min-height: 100vh;
  margin-left: -15rem;
  -webkit-transition: margin .25s ease-out;
  -moz-transition: margin .25s ease-out;
  -o-transition: margin .25s ease-out;
  transition: margin .25s ease-out;
  position:fixed;
  z-index: 1;
  height:100vh;
}

#sidebar-wrapper .sidebar-heading {
  padding: 0.875rem 1.25rem;
  font-size: 1.2rem;
}

#sidebar-wrapper .list-group {
  width: 15rem;
}

#page-content-wrapper {
  min-width: 100vw;
}

#wrapper.toggled #sidebar-wrapper {
  margin-left: 0;
}

.navbar {
  background: linear-gradient(to top right, #0084ff, #0084ff);
  position: fixed !important;
       width: calc(100% - 241px);
   top:0px;
  
}

@media (min-width: 768px) {
  #sidebar-wrapper {
    margin-left: 0;
  }

  #page-content-wrapper {
    min-width: 0;
    width: 100%;
  }

  #wrapper.toggled #sidebar-wrapper {
    margin-left: -15rem;
  }
}
