您好我已经找到了在导航栏下放置箭头的方法,但我无法在导航栏上工作。任何帮助将不胜感激。

<nav>

      <div class="hello"></div>
            <ul>
              <li class="icon-home"><a href="Premiership.html"><span>Home</span></a></li>

            <li class="arrow"> <a  class="star" href="#">England</a>
                <ul>
                    <li><a href="Premiership.html">Premiership</a>
                    </li>
                    <li><a href= "Unavailble.html">Championship</a>
                    </li>
                    <li><a href="Unavailble.html">League 1</a>
                    </li>
                    <li><a href="Unavailble.html">League 2</a>
                    </li>
                </ul>
            </li>
            <li class="arrow"> <a href="#">France</a>
                <ul >
                    <li id="r"><a href="Unavailble.html">Ligue 1</a> 
                    </li>
                </ul>
            </li>
            <li class="arrow"> <a href="#">Germany </a>

                <ul>
                    <li><a href="Unavailble.html">Bundesliga</a>
                    </li>
                </ul>
            </li>
            <li class="arrow"> <a href="#">Italy</a>

                <ul>
                    <li><a href="Unavailble.html">Serie A</a>
                    </li>
                </ul>
            </li>
            <li class="arrow"> <a href="#">Spain</a>
                <ul>
                    <li><a href="Unavailble.html">La Liga</a>
                    </li>
                </ul>
            </li>
        </ul>    
            <div class="handle"> Menu </div>
        </nav>

我认为css会起作用,但它没有

li a:after {
  content: '';
  display: none;
  width: 0;
  height: 0;
  border-top: 6px solid #333;
  border-right: 6px solid transparent;
  border-left: 6px solid transparent;
  position: absolute;
  z-index: 1;
  top: 100%;
  left: 50%;
  margin-left: -6px
}

在您的情况下,箭头就在那里,overflow:hidden上的ul表示您无法看到它。

我已经对您的代码进行了一些调整(请参阅下面的代码段),但需要进行一些调整才能完全按照您的意愿进行调整。为简单起见,我将箭头涂成了红色。

nav ul {
    /* overflow:hidden; REMOVE */ 
}

nav ul li.arrow:after {
  content: '';
  width: 0;
  height: 0;
  border-top: 6px solid red;
  border-right: 6px solid transparent;
  border-left: 6px solid transparent;
  position: absolute;
  z-index: 1;
  top: 100%;
  left: 50%;
  margin-left: -6px
}

  text-align: center;
  margin: 0;
  -webkit-transition: max-height 0.4s;
  -ms-transition: max-height 0.4s;
  -moz-transition: max-height 0.4s;
  -o-transition: max-height 0.4s;
  transition: max-height 0.4s;
}
nav ul li {
  display: inline-block;
  padding: 20px;
  width: 12.3%;
  text-align: center;

  border-top: 6px solid red;

  border-left: 6px solid transparent;
  position: absolute;
  z-index: 1;
  top: 100%;
  left: 50%;
  margin-left: -6px
}
nav ul ul {
  display: none;

  background-color: #399077;
  margin-left: -3%;

}
nav ul ul li {
