Question

我正试图将我的链接置于中间位置，但因为我在每个角落都有社交图标，所以它似乎不在中间。我得出了这个结论，因为箭头具有相同的左或右位置。我怎样才能做到这一点。行动中的代码可以在这里看到：

Answer 1

从箭头中删除position: absolute并更改其样式

.arrowleft {
    float: left;
    height: 28px;
    margin-top: 4px;
    width: 28px;
}

...

.arrowright {
    float: right;
    height: 28px;
    margin-top: 4px;
    width: 28px;
}

最后从float:left

中移除ul

Answer 2

或者，您可以像这样构建菜单：

<div id="wrapper">
<img class="arrowleft" src="css/img/arrow-left.png">
<ul>
  <li class="yellow"><a href="index.html">Firefox</a></li>
  <li class="green"><a href="index.html">Chrome</a></li>
  <li class="active"><a href="index.html">Safari</a></li>
  <li class="red"><a href="index.html">Opera</a></li>
  <li class="purple"><a href="index.html">Internet Explorer</a></li>
</ul>
<img class="arrowright" src="css/img/arrow-right.png">
</div>

并应用此css：

#wrapper {
    text-align:center;
    font-size:0px;
}
.arrowleft, .arrowright, ul, li {
    display:inline-block;
    zoom:1;
    *display:inline;
}

请务必从floats中的元素中移除#wrapper，以使其正确居中。另请记住在新的li声明中指定正确的字体大小。

zoom:和*display:inline是IE的修复，因为它们解决了内联块没有应用于没有内联和hasLayout属性的元素的错误。 font-size:0修复了元素之间应用的空间，因为它们是新行上的内联项。

顶部导航项目不居中
