Question

我有两个酒吧： 1.顶栏 - 名称，搜索栏，帐户，购物车 2.导航栏（带下拉菜单）

问题在于顶栏。我试图让所有元素都在同一条线上，右侧是Account和Cart。我尝试使用flex但现在搜索栏与其他元素不一致。活动帐户和购物车有点离线。当我不使用flex并且只是尝试将Account和Cart浮动到右边时，它们被交换（Cart首先出现，然后是Account），而且它们也没有排成一行，它们有点漂浮在顶层右。

HTML：

    <div class="top">
            <h1>TDX</h1>
            <form>
              <div>
                <input type="search" id="mySearch" name="q"
                placeholder="Search the site..." size="50">
                <button>Search</button>
              </div>
            </form>
            <a href="account.html"><h4>Account</h4></a>
            <a href="cart.html"><h4>Cart</h4></a>
        </div>
        <ul class="topnav">
          <li><a class="active" href="index.html">Home</a></li>
          <li class="dropdown"><a href="javascript:void(0)" class="dropbtn">Products</a>
              <div class="dropdown-content">
                <a href="#">Computers</a>
                <a href="#">Tablets</a>
                <a href="#">Cell Phones</a>
                <a href="#">Wearable Technologies</a>
                <a href="#">Accessories</a>
              </div>
          </li>  
          <li class="dropdown"><a href="javascript:void(0)" class="dropbtn">Brands</a>
              <div class="dropdown-content">
                <a href="#">Apple</a>
                <a href="#">Samsung</a>
                <a href="#">Lenovo</a>
                <a href="#">Dell</a>
                <a href="#">HP</a>
                <a href="#">Sony</a>
                <a href="#">Panasonic</a>
                <a href="#">Motorola</a>
                <a href="#">HTC</a>
              </div>
          </li> 
          <li><a href="deals.html">Deals</a></li>
        </ul>

CSS：

.topnav{
    list-style-type: none;
    margin: 0;
    padding: 0;
    overflow: hidden;
    background-color: #333;
    margin:0 auto;
    text-align:center;
}

.topnav li {
    float: left;
}

.topnav li a, .dropbtn {
    display: inline-block;
    color: white;
    text-align: center;
    padding: 14px 16px;
    text-decoration: none;
    width:120px;
}

.topnav li a:hover, .dropdown:hover .dropbtn {
    background-color: #111;
}

li.dropdown {
    display: inline-block;
}

.dropdown-content {
    display: none;
    position: absolute;
    background-color: #f9f9f9;
    min-width: 160px;
    box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
    z-index: 1;
}

.topnav .dropdown-content a {
    color: black;
    padding: 12px 16px;
    text-decoration: none;
    display: block;
    text-align: left;
}

.topnav .dropdown-content a:hover {background-color: #f1f1f1;}

.dropdown:hover .dropdown-content {
    display: block;
}

.top{
    display: flex;
    align-content: space-between;
}

.top a{
    margin: 0 5px;
}

.top h1, .top a{
    flex: 0 1 auto;
}

.top form{
    flex: 1 1 auto;
    vertical-align:middle;
}

This is a screenshot of how it looks

Answer 1

将align-items: center;添加到CSS中的.top元素。

您更新的.top CSS元素：

.top {
    display: flex;
    align-content: space-between;
    align-items: center;
}

形式不是在flexbox中垂直居中
