Html div和ul内部图标的中心列表

我有一个分为两行的图标列表，我试图将它们居中，但似乎没有任何效果。下面是我现在为CSS准备的内容：

.overview {width:49%; margin-bottom: 10px;}
.latest {width:100%; margin-bottom: 10px;}
.home {width: 100%; overflow: hidden;}
.leftside {text-align:center;}
.homebox {width: 100%; float: center; margin-bottom: 10px; background: #fff; overflow: hidden;}
.homebox2 {width: 100%; float: center; margin-bottom: 10px; background: #fff; overflow: hidden;}
.header {background: #6c6c6c; color: #FFF; border-bottom: 1px solid #6c6c6c; padding: 5px; font-size: 14px; font-weight: bold;}
.inside {background: #FCFCFC; border: 1px solid #6c6c6c; padding: 10px; height: 100%;}
.dashboard-heading {background: #146091;}

#icons {float: center; list-style: none; margin:0; padding:0;}
#icons a {text-decoration: none;}
#icons li {float: left; width: 100px; height: 100px; border:1px solid #ccc; margin: 0 7px 7px 0;}
#icons li:hover {border:1px solid #aaa; background: #ddd;}
#icons li img {padding: 8px 18px 2px 18px; align: center;}
#icons li h6 {color: #333; font-size:12px; text-align: center; margin:0; padding:0;}

#icons2 {float: center; list-style: none; margin:0; padding:0;}
#icons2 a {text-decoration: none;}
#icons2 li {float: left; width: 100px; height: 100px; border:1px solid #ccc; margin: 0 7px 7px 0;}
#icons2 li:hover {border:1px solid #aaa; background: #ddd;}
#icons2 li img {padding: 8px 18px 2px 18px; align: center;}
#icons2 li h6 {color: #333; font-size:12px; text-align: center; margin:0; padding:0;}

这就是我的HTML的内容：

    <div class="leftside">
        <div class="homebox">
        <ul id="icons">
            <li>
                <a href="<?php echo $product; ?>">

    </div>

我知道这可能是一些小的或愚蠢的事情需要解决，我只是觉得我一直在看这个，需要一些新鲜的眼睛。谢谢

嗯，没那么难

ul#icons{text-align:center}
#icons li{display:inline-block;
/*remove 'float:left'}

---

瞧：

从

li

元素中删除

float:left

，然后添加

display:inline块

---

[在html中]

float:center通常不太受支持。：）哈哈，是的，我一直在反复尝试我能想到的一切；）如果将一个容器的宽度设置为text align:center，并且容器内的元素是display:inline而不是浮动的，那么它们应该居中。哇。有浮子：中心？
