jquery - 如何使容器div垂直居中

Question

我无法将包含广告类型容器的 popup_interstitial_table 垂直居中。

fiddle 是自动解释的:http://jsfiddle.net/NomikOS/D8LLM/

jQuery solutions are welcome too.

HTML:

<div id="popup_interstitial">
    <div id="parent">
        <div id="popup_interstitial_pro_head_text">
            Headline text 
        </div>
        <div id="child">
            <div id="popup_interstitial_table">
                <div id="popup_interstitial_row2">
                    <div id="popup_interstitial_title"><?php echo $title; ?></div>
                    <img id="popup_interstitial_image" src="<?php echo $image; ?>">
                    <div id="popup_interstitial_description"><?php echo $description; ?></div>
                </div>
            </div>
        </div>
    </div>
</div>

相关的CSS代码是:

#popup_interstitial_pro_head_text{
    color:#FFF; 
    font-size: 2em;
    font-weight: normal;
    text-shadow: 0.05em 0.05em #666;
    background-color: #A5CF4C;
    width: 100%;
    padding-left: 1%;
    padding-top: 0.8%;
    padding-bottom: 0.8%;
    border-top-width: thin;
    border-top-style: solid;
    border-top-color: #648323;
    border-bottom-width: thin;
    border-bottom-style: solid;
    border-bottom-color: #759928;
    margin-bottom: 2%;
    -webkit-box-shadow: 1px 1px 8px #333333;
    -moz-box-shadow: 1px 1px 8px #333333;
    khtml-box-shadow: 1px 1px 8px #333333;
    filter: shadow(color=#333333, direction=135, strength=0);
}
#popup_interstitial {
    display: none;
    width: 100%;
    height: 100%;
    position: fixed;
    background-color:#FFFFFF;
    color:#111;
    z-index:9999;
    top:0;
    left:0;
}
#popup_interstitial_table {
    width: 50%;
    margin: 0 auto 0 auto;
    background-color:#E7E7E7;
    padding: 1em 2.2em;
    font: 0.85em "Trebuchet MS", Arial, Helvetica, sans-serif;
    margin-top: 5%;
    vertical-align: center;

}
#popup_interstitial_title{
    color:#FFF; 
    font-size: 1.5em;
    font-weight: bold;
    padding: 0 0 0 0.3em;
    border-bottom-width: thin;
    border-bottom-style: solid;
    border-bottom-color: #777;
    background-color: #888; 
    border-radius: 0.3em;
}
#popup_interstitial_description{
    padding-top: 1.7em;
    padding-bottom: 1.2em;
    border-bottom-width: thin;
    border-bottom-style: solid;
    border-bottom-color: #ccc;
    line-height:1.5em;
}

#popup_interstitial_image{
    vertical-align: baseline;
    margin: 25px 20px 3px 0;
    -webkit-box-shadow: 1px 1px 8px #333333;
    -moz-box-shadow: 1px 1px 8px #333333;
    khtml-box-shadow: 1px 1px 8px #333333;
    filter: shadow(color=#333333, direction=135, strength=0);
    padding: 4px;
    margin-left: 6px;
    float: left;
}

这是最重要的:

#parent {position: relative;}
#child {
    padding: 0% 0;
    margin: 0 auto; 
}

Answer 1

使用这个CSS:

#child {
    display: table
}
#popup_interstitial_table {
    display: table-cell;
    vertical-align: middle;
    text-align: center
}

并向其中添加其他 CSS。
