下拉菜单没有正确调整大小

Question

我有一个包含元素的导航栏，其中两个是下拉菜单。我修改了导航栏上元素的大小，但我无法在下拉的元素上执行此操作。当下拉下降时，它太宽，但是当我将鼠标悬停在元素上时，只有一部分是固定宽度＆＃34;我指定的是突出显示，其余的不是。我希望它们都是100px而侧面没有多余空间，我该怎么做？

代码：

＆＃13;

＆＃13;

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

.topnav ul {
  list-style-type: none;
  margin: 0 auto;
}

.topnav li {
  float: left;
}

.topnav li a,
.dropbtn {
  display: inline-block;
  color: white;
  text-align: center;
  padding: 14px 16px;
  text-decoration: none;
  width: 100px;
}

.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;
}

＆＃13;

<div class="topnav">
  <ul>
    <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="#">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="#">Motorola</a>
        <a href="#">HTC</a>
      </div>
    </li>
    <li><a href="deals.html">Deals</a></li>
  </ul>
</div>
