HTML下拉列表无法正确定位

Question

我已经制作了一个下拉菜单，可用于我的网站nagivation栏中的三个不同链接。下拉本身工作正常然而我遇到的问题是我无法将下拉列表定位在每个导航链接的中间，它正确定位于其中一个链接，但另一个不是因为它们是不同的字符长度。下拉列表完全在HTML和CSS中完成，网站的其余部分也使用Django，但下拉列表中没有使用它。

问题图片 -

（这是下拉列表未正确定位的链接之一，您可以看到框顶部的三角形没有与链接的中间对齐。）

（在这一个你可以看到三角形或多或少以链接为中心，但我相信这只是偶然的）

下拉HTML（对于其中一个下拉列表，但它与其他下拉列表相同）

      <li class="link-drop"><a href="">Employer</a>
          <ul class="link-drop-ul">
              <div class="triangle"></div>
              <div class="link-drop-box">
                  <li><a class="link-drop-a" href="{% url 'createjoblisting' %}">Add Listing</a></li>
                  <li><a class="link-drop-a" href="{% url 'featurenotimplemented' %}">How it works</a></li>
              </div>
          </ul>
      </li>

下拉CSS（所有内容都相同）

.link-drop {
    list-style-type: none;
    display: inline;
    font-size: 16px;
    cursor: pointer;
    list-style-type: none;
    display: inline-block;
    float: right;
    margin: auto;
    text-align: center;
}
.link-drop li {
    list-style-type: none;
}
.link-drop a {
    text-decoration: none;
    color: #ebebee;
    float: right;
    margin-top: 18px;
    margin-right: 9px;
    margin-left: 9px;
    list-style-type: none;
}
.link-drop-ul {
    display: none;
    position: absolute;
    text-align: center;
    padding-top: 18px;
    -webkit-transition: all .1s ease-out;
    -moz-transition: all .1s ease-out;
    -ms-transition: all .1s ease-out;
    -o-transition: all .1s ease-out;
    transition: all .1s ease-out;
}
.link-drop-box {
    padding-bottom: 1px;
    padding-top: 1px;
    background-color: white;
    box-shadow: 0px 0px 38px -10px black;
    border-radius: 5px;
    width: 122px;
    margin: auto;
}
.triangle {
    width: 0;
    height: 0;
    position: relative;
    border-left: 8px solid transparent;
    border-right: 8px solid transparent;
    border-bottom: 8px solid white;
    left: 50%;
    margin-left: -8px;
}
.link-drop-ul li {
    margin-top: 15px;
    margin-bottom: 15px;
}
.link-drop-ul li a {
    color: black;
    float: none;
}
.link-drop-ul li a:hover {
    color: #d1d1d1;
}
.link-drop:hover > .link-drop-ul {
    display: block;
    position: absolute;
    padding-top: 55px;
    padding-left: 0px;
    margin-top: 10px;
}

感谢任何帮助，谢谢！
