导航按钮的宽度

Question

我有一个包含行内块li的导航。每个li包含两个block span元素，因此它在翻转时显示动画。我的问题是与中心对齐和间距的li导航。我不想给li标签一个最小宽度。有人能帮忙吗?

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;
text-align: center;

}
#nav li{
height: 16px;
line-height: 15px;
overflow: hidden;
display: inline-block;
padding: 0px 25px 0px 25px;
position: relative;
}
li span.top {
color: #16528e;
top: -18px;
}
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在li span下创建此问题。你需要删除它，你会得到你的效果，通过应用负top到这个css。

例如

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;
}

这就是解决方案。
