Question

我的头类.list-holder的div没有根据div中的内容调整大小。如果我增加列表项的填充，则内容在div之外溢出。我已经导入了引导CDN

.list-holder {
    background-color: rgba(0,0,0,0.8);
    margin: 0px 40px;
    margin-top: 15px; 
    display: flex;
    justify-content: center;
    align-items: center;
}

.list-holder > ul > li{
    display: inline;
    padding: 10px;
    border: solid 1px;
}

.list-holder > ul > li > a{
    display: inline;
    color: white;
    text-decoration: none;
}

.list-holder > ul{
    margin: 0px;
    padding: 0px;
}

<body>
    <div class="branding">
        <h1>Blogging</h1>
        <div class="search-btn">
            <button >Get started</button>
            <div class="search">
                <input type="search" placeholder="Google Search ">
                <i class="fas fa-search"></i>

    </div>
    <div class="view-users">
        <div style="display: flex">
            <div class="views">Total Views: 0</div>
            <div class="users">Total Users: 0</div>
        </div>
    </div>
    <header>

Answer 1

您的li元素应具有display: inline-block而不是display: inline，以便触发父元素中的高度修改。

但是，如果您想使用引导程序，则可以执行以下操作来实现所需的功能（展开代码段以查看居中的菜单项）：

nav.navbar-dark.bg-dark {
  background-color: rgba(0,0,0,0.8)!important;
}
@media (min-width: 1200px) {
  h1.navbar-brand {
    position: absolute;
  }
  nav .form-inline {
    position: absolute;
    right: 15px;
  }
}

您可以使用display: inline-block代替display: inline来 .list-holder> ul> li

div的高度未根据内部内容调整大小
