Question

我尝试在各种类别下创建下拉菜单，但每当我将鼠标悬停在这些菜单上时，下拉菜单会显示在按钮的左侧。有关如何修复的任何建议？链接到我的代码

这是jsFiddle链接：

          Uganda was formed from the colonization of the Buganda Kingdom by the British in the 19th century. Britain wanted to protect the viability of the Nile River for its trading potential which prompted the British government to annex Buganda to create the
          Uganda Protectorate in 1894. In 1962 Uganda regained its independence and declared itself a republic with Milton Obote as the first prime minister and former Bugandan King Muteesa as the president. Despite being largely ceremonial, Obote removed
          the presidential position and established a new constitution in which he became a powerful president similar to a dictator. After committing many atrocities Obote was removed from power in a coup orchestrated by General Idi Amin who seized control
          of the country. Amin proceeded to be nearly as atrocious as Obote when almost 500,000 citizens perished under his regime. Despite entering presidency with cheers, his actions made the country of Uganda hate him. After Amin was removed from power
          by largely Tanzanian forces, Obote returned to presidency. A war broke out as a result from the election resulting in the deaths of between 100 and 500,000 people. This compelled 2 military commanders to conduct a coup in which Museveni gained
          control. Yoweri Museveni remains in power till this date."

图像不起作用，但这不重要吗？

Answer 1

您应该删除为类.dropdown-content的所有元素插入的内联样式。

<div class="dropdown">
    <button class="dropbtn">CONTACT</button>
    <div class="dropdown-content" style="POSITION: relative; TOP: 20px;">
        <a href="#">contact</a>
    </div>
</div>

这称为内联样式。直接在html元素上编写的样式：

style="POSITION: relative; TOP: 20px;"

接下来，您需要修改.dropdown-content的规则：

.dropdown-content{
    /* Your code here */
    top: 100%; 
}

为什么我的按钮左侧的下拉元素不在下面？
