我调用哪个元素来提供填充或边距，所以我在底部有空间

Question

我有如下简单的 CSS3 导航，

我需要在名为“链接到我们的客户”的下拉菜单的最后一个列表项之后的空间。我想知道需要调用哪个元素。

HTML 代码

<ul class="menu">

<li><a href="#">Home</a></li>
<li><a href="#">Why Us</a>

    <ul>
        <li><a href="#">About Us</a></li>
        <li><a href="#">Meet the Team</a></li>
        <li><a href="#">Frequently Asked Questions</a></li>
        <li><a href="#">What our Client Say</a></li>
        <li><a href="#">Our Promises</a></li>
        <li><a href="#">Complete Profit Guide</a></li>
         <li><a href="#">How to choose an Accountant </a></li>
           <li><a href="#">Links to Our Clients</a></li>
    </ul>

</li>
<li><a href="#">Services</a></li>

<li><a href="#">RTI</a></li>
<li><a href="#">Company Foundation</a></li>
<li><a href="#">Auto Enrolment</a></li>
<li><a href="#">Client Area</a></li>
<li><a href="#">Contact Us</a></li>


</ul>

提前致谢。我认为某些父元素属性正在影响。

Answer 1

您可以通过在其中一个上放置 padding-bottom 来解决它：

.menu ul

或

.menu ul li:last-child

Answer 2

你有以下几点：

.menu ul li {
    height: 0;
    overflow: hidden;
    padding: 0;

    -webkit-transition: height .25s ease .1s;
    -moz-transition: height .25s ease .1s;
    -o-transition: height .25s ease .1s;
    -ms-transition: height .25s ease .1s;
    transition: height .25s ease .1s;
}

您将填充设置为零。增加填充将在底部增加空间（但也在每个项目之间）。您可以添加以下内容：

.menu ul li:last-child {
    padding-bottom: 10px;     //or however much space you want
}

这只会为底部元素添加填充（看起来就像你想要的那样）

正如其他人所说，为.menu ul添加填充将具有相同的视觉效果：

.menu ul {
    padding-bottom: 10px;
}

Answer 3

您应该在 .menu li ul li 处放置一个填充。 它会为您的代码的每个 li 设置样式。但您可能不希望这样，所以将 padding-bottom 添加到您的 .menu li ul

你不需要最后一个子元素或任何其他伪元素 这应该工作：

 .menu li ul{
    padding-bottom:10px;
 }

Answer 4

我给你修好了code here

.menu ul li:last-child a {
  border: none;
  padding-bottom: 10px;
  background-color: #547AA6;
}
