将元素放在文本后面

时间：2018-11-11 14:29:09

标签： jquery html css

我的水平栏上有这样的链接：

<div class="blackbar">
    <span class="blackbar-text"><a href="news.php">NEWS</a></span>
    <span class="blackbar-text"><a href="foo.php">FOO</a></span>
    <span class="blackbar-text"><a href="bar.php">BAR</a></span>
</div>

使用此CSS：

div.blackbar {
    margin: 0px;
    padding-left: 20px;
    padding-right: 10px;
    padding-top: 6px;
    text-align: center;
    vertical-align: middle;
    background-color: #888;
}
.blackbar-text {
    padding: 0px 12px;
    font-size: 17px;
    font-weight: 900;
    text-shadow: 0 -1px 0 #000;
}
.blackbar-text a:link,.blackbar-text a:visited {
    color:#e8e8e8;
}

现在，当您将鼠标悬停在其中一个跨度上时，图层应出现在文本后面但在blackbar-div上方。还应该可以扩展blackbar-div的边框，因为它应该像一个包含子菜单的下拉元素。

我可以使用jquery轻松处理mouseover / out部分，但是如何放置HTML和CSS以获得效果？

基本上，＃teams div应该在文本和背景栏之间移动，如下所示：

您应该将所有范围更改为div，并将.blackbar-text设置为显示：inline-block;所以他们排队。然后在.blackbar-text div之一下添加一个带有嵌套链接的div 

  <div class="blackbar-text dropdown">
    <a href="bar.php">BAR</a>
        <div class="dropdown-content">
        <a href="#">Link 1</a>
        <a href="#">Link 2</a>
        <a href="#">Link 3</a>
      </div>
  </div>

位置.dropdown-content绝对，并将显示设置为无。然后下拉魔术就在这里发生。将：hover psuedo-class应用于.dropdown .dropdown-content display：块，这具有您想要的悬停效果。

.dropdown:hover .dropdown-content {
    display: block;
}

这是我的解决方案的链接。 https://jsfiddle.net/tophermurphy/o4su1Lbd/19/

对于颜色，您可以根据自己的需要进行更改

答案 2 :(得分：-1)

您不想使用span类，并且不需要javascript。您想将嵌套竞争设置为display：none，然后使用伪类：hover来显示块。显示元素。这是一个例子 https://www.w3schools.com/css/tryit.asp?filename=trycss_dropdown_navbar

答案 3 :(得分：-2)

：您要在css中悬停鼠标。

只要出现这种情况，就可以执行以下操作。

.blackbar-text:hover{
   background: #f00;
}

可以根据需要修改颜色。
