菜单对齐居中和浮动问题

我的网站标题和导航功能可以根据需要运行。但是链接和徽标的布局未对齐。

它应该如下所示。

链接-链接-链接-----徽标-----链接-链接-下拉

但是显示如下

链接-链接-徽标--------------下拉菜单-链接-链接

徽标将不会居中居中。.下拉列表显示在右侧链接之前。

Flexbox看起来是合理的解决方案。我删除了所有float属性，添加了div容器以包装出现在右侧的项目，并将flexbox属性添加到了nav元素。

#siteHeader {
  max-width: 1600px;
  padding-top: 15px;
  height: 93px;
  font-size: 12px;
  text-transform: uppercase;
  background-color: #000;
  margin-left: auto;
  margin-right: auto;
  border-top: 1px solid #d7d5d5;
}
#siteHeader a {
  text-decoration: none;
}
.logo {
  display: block;
  height: 55px;
  width: auto;
  float: left;
}

.nav {
  display: flex;
  flex-direction: row;
  justify-content: space-between;
}

.right, .left{
  display: inline-flex;
}
ul {
  list-style-type: none;
  margin: 0;
  padding: 0;
  overflow: hidden;
  width: auto;
}
li {
  float: left;
}
li a {
  display: block;
  color: white;
  text-align: center;
  padding: 6px 16px;
  text-decoration: none;
  float: left;
}
li a:hover {
  background-color: #000;
}
.dropbtn {
  background-color: #000;
  color: white;
  padding-top: 6px;
  padding-bottom: 25px;
  border: none;
  cursor: pointer;
  min-width: 100px;
  text-transform: uppercase;
}
.dropdown {
}
.dropdown-content {
  display: none;
  position: absolute;
  background-color: #434343;
  min-width: 185px;
  right: 9px;
}
.dropdown-content a {
  color: white;
  padding: 13px 16px;
  text-decoration: none;
  display: block;
}
.dropdown-content a:hover {
  background-color: #000000
}
.dropdown:hover .dropdown-content {
  display: block;
  float: left;

.dropdown:hover .dropbtn {
