Bootstrap 导航栏过渡不流畅

Question

我的 bootstrap 导航栏有以下 HTML 代码。

<nav class="navbar navbar-expand-lg navbar-dark" style="background-color:
      rgb(50, 50, 50)">
        <button
          class="navbar-toggler"
          type="button"
          data-toggle="collapse"
          data-target="#navbar"
        >

         <h1><i class="fas fa-bars" ></i></h1>

        </button>

        <div class="collapse navbar-collapse" id="navbar">
          
          <div class="navbar-nav">
            <div>
              <a class="nav-item nav-link" id="signUp" href="/SignUp">
                <h1>Sign Up&nbsp;&nbsp;</h1></a>
              <a class="nav-item nav-link" id="login" href="/LoginOrDeleteAccount">
                <h1>Login Or Delete Account</h1></a>
            </div>
          </div>
        </div>
      </nav>

我尝试使用下面的 Css 代码更改导航栏折叠或展开的速度。

#navbar{
    transition:height 2s ease;
}

上面的代码有效，但是导航栏没有展开或折叠smoothly.How我可以解决这个问题吗？

Answer 1

尝试将按钮属性从 data-toggle 更改为 data-bs-toggle，将 data-target 更改为 data-bs-target

<button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbar">

使用 Bootstrap 3.4.1 版本更新了工作代码段

注意：用于显示链接列表的可切换上下文菜单。与 dropdown JavaScript plugin 互动。这意味着您必须通过 javascript

调用下拉列表

例如：

// Call the dropdowns via JavaScript___
$('.dropdown-toggle').dropdown();

请检查以下工作片段

$('.dropdown-toggle').dropdown();
