Question

我有一个包含内联块li的导航。每个li包含两个块跨度元素，因此它在翻转时动画。我的问题是li导航的中心对齐和间距。我不想给li标签一个最小宽度。任何人都可以帮忙吗？

HTML：

<div id="nav">
    <ul>
        <li class="button">

                <a href="#">
                    <span class="top">Home</span>
                    <span class="bottom">Home</span>
                </a>

        </li>

        <li class="button"> 

                <a href="#">
                    <span class="top">About</span>
                    <span class="bottom">About</span>
                </a>

        </li>

        <li class="button">

                <a href="#">
                    <span class="top">Equine</span>
                    <span class="bottom">Equine</span>
                </a>

        </li>

        <li class="button">

                <a href="#">
                    <span class="top">Canine</span>
                    <span class="bottom">Canine</span>
                </a>

        </li>

        <li class="button">

                <a href="#">
                    <span class="top">Rates & Travel</span>
                    <span class="bottom">Rates & Travel</span>
                </a>

        </li>

        <li class="button">

                <a href="#">
                    <span class="top">Case Study & News</span>
                    <span class="bottom">Case Study & News</span>
                </a>
        </li>

</div> <!---nav---->

CSS：

#nav {
height: 25px;
border-top: 2px solid #FFFFFF;
border-bottom: 1px solid #C7C7C7;
padding: 10px 0px 5px 0px;

#nav li{

line-height: 15px;
overflow: hidden;
display: inline-block;
padding: 0px 25px 0px 25px;
position: relative;
}

li span.top {

}

a:hover span {
top: 18px;
}
a:hover span.top {
top: 0;
}

li span {
display: block;
top: 0;
position: absolute;
  -webkit-transition: top 0.3s, border 0.3s, color 0.35s;
  -moz-transition: top 0.3s, border 0.3s, color 0.35s;
  -ms-transition: top 0.3s, border 0.3s, color 0.35s;
  -o-transition: top 0.3s, border 0.3s, color 0.35s;
  transition: top 0.3s, border 0.3s, color 0.35s;
}

Answer 1

position:absolute正在li span下创建此问题。您需要删除它，并通过将负top应用于此css来获得效果。

For Instance，

li span {

   display: block;
   position: relative;
   top: -15px;
  -webkit-transition: top 0.3s, border 0.3s, color 0.35s;
  -moz-transition: top 0.3s, border 0.3s, color 0.35s;
  -ms-transition: top 0.3s, border 0.3s, color 0.35s;
  -o-transition: top 0.3s, border 0.3s, color 0.35s;
  transition: top 0.3s, border 0.3s, color 0.35s;
}

这是Solution。

希望这有助于。
