Question

我无法将下拉列表与栏的其余部分（下面的代码）对齐。我尝试使用边距和填充，但这也无济于事。任何指导将不胜感激。

我需要下拉菜单位于栏的右上角。你不必为我做代码，但我想弄清楚是否有两种不同的风格相互交叉并导致这个或我接下来应该做什么？

Answer 2

其中一个变种是使用flexbox for headDivider

.headDivider {
  background-color: #ff7200;
  color: #ffffff;
  font-size: 30px;
  line-height: 50px;
  height: 63px;
  vertical-align: middle;
  padding-top: 3px;
  display: flex;
  justify-content: space-between;
  align-items: center;
}
