HTML 下拉菜单无法正确定位

Question

我制作了一个下拉菜单，用于我网站导航栏中的三个不同链接。下拉菜单本身工作正常但是我遇到的问题是我无法让下拉菜单将自己定位在每个导航链接的中间，它针对其中一个链接正确定位但是另一个不是因为它们具有不同的特征长度。下拉菜单完全用 HTML 和 CSS 完成，网站的其余部分也使用 Django，但它没有在下拉菜单中使用。

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 Angular 形未与链接的中间对齐。)

(在这个中你可以看到三 Angular 形或多或少以链接为中心，但我相信这只是偶然)

下拉 HTML(其中一个下拉列表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(这在所有地方都一样)

.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!

这是您所面临问题的解决方案。我更改/移动/添加了一些 CSS。

.link-drop {
    position:relative;
    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;
    width: 122px;
    text-align: center;
    -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;
    padding: 0;
    margin:0;
    left: 50%;
    -moz-transform: translatex(-50%);
    -ms-transform: translatex(-50%);
    -o-transform: translatex(-50%);
    -webkit-transform: translatex(-50%);
    transform: translatex(-50%);
    top:100%;
    padding-top:20px;
}
.link-drop-box {
    padding-bottom: 1px;
    padding-top: 1px;
    background-color: white;
    box-shadow: 0px 0px 38px -10px black;
    border-radius: 5px;
    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;

}

<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>
