响应式菜单修复

Question

请全屏观看。 每当我单击菜单箭头将其最小化时，我都希望菜单中的文本和徽标文本消失。 我只想留下图标并使它们居中。 什么是最好的方法来做到这一点？ 我曾尝试对一个菜单使用 style display none 并添加另一个菜单，但在添加 display 属性时没有过渡。

 function smallNav() { let menu = document.getElementById('sidebar-container'); menu.style.width = "5rem"; }

 .router-link-active { background-color: #2b445f; font-weight: 700; border-left: 3px solid #1089ff; } #right, .left { cursor: pointer; } #sidebar-container { min-height: 100vh; transition: 400ms; bottom: 0; width: 18rem; background: #23374d; } #sidebar-small { min-height: 100vh; transition: 400ms; bottom: 0; width: 0px; background: #23374d; } #sidebar-container .logo { padding: 20px; } .menuicon { font-size: 24px; } .menu { transition: 200ms; } .menu a { color: white; } .btn-search { right: 5px; } .left { color: white; font-size: 24px; } .avatar { max-width: 43px; } .menu a { padding: 10px; width: 100%; } .menu a:hover { background-color: #2b445f; } ion-icon { font-size: 24px; color: #fff !important; } @media (max-width: 768px) { #sidebar-container { display: none; } #mobile { display: flex !important; flex-direction: column; text-align: left; } #mobile li { padding: 20px; } .btn-search { bottom: 0; } }

Answer 1

您可以像下面一样更改您的来源。 您的 CSS 没有改变，但我在您的 HTML 标签和 js 代码中添加了一些更改。

 function smallNav() { let menu = document.getElementById('sidebar-container'); menu.style.width = "4rem"; document.getElementById('logo-name').hidden = true; for(i=0; document.getElementsByClassName('menu-title').length - 1; i++) document.getElementsByClassName('menu-title').item(i).hidden = true; }

 <div> <div class="d-flex"> <div class="bg-primary text-left" id="sidebar-container"> <div class="logo p-3 d-flex justify-content-between align-items-center"> <h4 class="text-white" id="logo-name">Company Name</h4> <div class="i fas fa-chevron-circle-left left" id="left" onClick="smallNav()"></div> </div> <div class="menu d-flex flex-column"> <router-link class="nav-link mt-4 d-flex py-3" :to="{name: 'Home'}" exact="true"> <div class="d-flex align-items-center"> <i class="fas fa-home mr-3 menuicon"> </i><span class="menu-title">Home</span></div> </router-link> <router-link class="nav-link text-white py-3" :to="{name: 'About'}"> <div class="d-flex align-items-center"> <i class="fas fa-home mr-3 menuicon"></i><span class="menu-title">Plan</span> </div> </router-link> </div> </div> <div class="w-100"> <nav class="navbar navbar-expand-lg navbar-light bg-light"> <div class="container-fluid pl-0 pr-0"> <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation"><span class="navbar-toggler-icon"></span></button> <form class="form-inline my-2 position-relative d-inline-block"> <input class="form-control mr-sm-2" type="search" placeholder="Search" aria-label="Search" /> <button class="btn position-absolute btn-search" type="submit"><i class="fas fa-search"> </i></button> </form> <div class="collapse navbar-collapse" id="navbarSupportedContent"> <ul class="navbar-nav ml-auto"> <li class="nav-item dropdown"><a class="nav-link dropdown-toggle d-flex align-items-center" id="navbarDropdown" href="#" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false"><img class="avatar mr-2 img-fluid" src="https://www.kindpng.com/picc/m/464-4644512_circle-avatar-picture-png-transparent-png.png" />Jan Kowalski</a> <div class="dropdown-menu" aria-labelledby="navbarDropdown"><a class="dropdown-item" href="#">Mój profil</a><a class="dropdown-item" href="#">Subskrypcja</a> <div class="dropdown-divider"></div><a class="dropdown-item" href="#">Wyloguj</a> </div> </li> <div class="d-none" id="mobile"> <li class="nav-item"></li>Home <li class="nav-item"></li>About <li class="nav-item"></li>About </div> </ul> </div> </div> </nav> </div> </div> </div>
