它没有居中对齐

Question

我在我的wordpress主题中使用这段代码来居中对齐，它不起作用，但如果我右对齐或左对齐，它就会起作用。

  <table border="1" align="center">
  <tr>
    <td>
      <div style='width: 435px; height: 90px; background-image: url( http://vortex.accuweather.com/adcbin/netweather_v2/backgrounds/spring1_435x90_bg.jpg ); background-repeat: no-repeat; background-color: #607041;' >
       <div id='NetweatherContainer' style='height: 75px;' >
        <script src='http://netweather.accuweather.com/adcbin/netweather_v2/netweatherV2ex.asp?partner=netweather&tStyle=normal&logo=1&zipcode=MEA|AE|AE005|DUBAI|&lang=eng&size=10&theme=spring1&metric=0&target=_self'></script>
     </div>
     <div style='text-align: center; font-family: arial, helvetica, verdana, sans-serif; font-size: 10px; line-height: 15px; color: #FDEA11;' >
      <a style='color: #FDEA11' href='http://www.accuweather.com/world-index-forecast.asp?partner=netweather&locCode=MEA|AE|AE005|DUBAI|&metric=1' >Forecast</a> | <a style='color: #FDEA11' href='http://www.accuweather.com/maps-satellite.asp' >Maps</a> | <a style='color: #FDEA11' href='http://www.accuweather.com/index-radar.asp?partner=accuweather&zipcode=MEA|AE|AE005|DUBAI|' >Radar</a>
     </div>
     <img style='float: right; padding-right: 5px;' src='http://vortex.accuweather.com/adc2004/common/images/misc/netweather_v2/adcwhite.png' /><div style='clear: both;' />
   </div>
 </div>
</td>

Answer 1

如果你只想显示一张图片，只需将该图片的容器居中，而不是使用table元素：

.ad {
    display: block;
    margin:  0 auto;
}
.w435 {
    width:   435px;
}

然后给你的div一个宽度(你已经有了)：

<div class="ad w435"><!-- content --></div>
