Question

在我创建的这个模型中，每当鼠标悬停在主导航上的按钮上时，我都会尝试在每个按钮下面创建一个自定义箭头形状。但是，每个按钮的宽度会有所不同，我需要它看起来一样。我如何在CSS中实现这一目标？ Click Here看看我想要实现的目标＆＃39;我是新的＆＃39;链接。

到目前为止，这就是我在style.css中所拥有的：

.main_nav_inside {
  margin: 0 auto;
  margin-top: -130px;
  position: relative;
  z-index: 1;
}

.main_nav_inside ul {
  list-style-type: none;
  margin: 0;
  float: right;
}

.main_nav_inside ul li {
  display: inline-block;
  float: left;
  font-family: 'Roboto', sans-serif;
  font-size: 20px;
  font-weight: 500;
  text-transform: uppercase;

}

.main_nav_inside ul li a {
  display: block;
  top: 0;
  padding-left: 20px;
  padding-right: 20px;
  padding-top: 50px;
  height: 130px;
  color: #ffffff;
}

.main_nav_inside ul li a:hover {
  padding-bottom: 5px;
  width: 100%;
  background-color: #2F2F2F;
}

.main_nav_inside ul li a:hover:before {
  padding-bottom: 20px;
  width: calc(2% + 30px);
  background-color: #000000;
  content: '';
  position: absolute;
  margin: 0 auto;
  left: inherit;
  margin-left: -20px;
  margin-right: 0;
  top: 120px;
  height: 20px;
  background: #000000;
  -webkit-transform: skew(0deg, 0deg);
  -moz-transform: skew(0deg, -6deg);
  -ms-transform: skew(0deg, -6deg);
  -o-transform: skew(0deg, -6deg);
  transform: skew(0deg, 15deg);
  z-index: -1;
}
.main_nav_inside ul li a:hover:after {
  padding-bottom: 20px;
  width: calc(10% / 2);
  background-color: #000000;
  content: '';
  position: absolute;
  margin: 0 auto;
  right: inherit;
  margin-left: -35px;
  margin-right: 0;
  top: 120px;
  height: 20px;
  background: #000000;
  -webkit-transform: skew(0deg, 0deg);
  -moz-transform: skew(0deg, -6deg);
  -ms-transform: skew(0deg, -6deg);
  -o-transform: skew(0deg, -6deg);
  transform: skew(0deg, -15deg);
  z-index: -1;
}

以下是此页面的HTML：

<header id="header_inside">
      <div class="main_logo_white"><a href="{{ siteUrl }}"><img src="{{ siteUrl }}/images/ssumc_logo_white.png"></a></div>

  {% set parents = craft.entries.section('menu').level(1).limit(5) %}
  <nav class="main_nav_inside">
      <ul>
        {% nav parent in parents %}
        <li>
          {{ parent.getLink() }}
            {% ifchildren %}
              <ul class="dropdown">
                  <li>{% children %}</li>
              </ul>
            {% endifchildren %}
        </li>
          {% endnav %}
      </ul>

  </nav>
</header>

I was able to create the shape using border-top, border-left and border-right. But the bottom tip seems to stay flat and doesn't have a point to it. No matter what numbers you adjust in the border width of top, left or right the tip will stay flat.

.main_nav_inside ul li a:hover:after {
    top: 100%;
    left: 0;
    right: 0;
    content: " ";
    position: absolute;
    border-top: 20px solid #000000;
    border-left: 50px solid rgba(0, 0, 0, 0);
    border-right: 50px solid rgba(0, 0, 0, 0);
}
