css - 文本在 IE 中不显示在图像下方

Question

Fiddle Here

我的问题是，为什么在 IE(8 及更早版本)中标题文本没有显示在缩略图下方。在所有其他浏览器中工作正常。

HTML:

<div id="thumbsGrid">
    <div class= "thumbs">
        <a href="http://youtu.be/A30XhK8Vtmg">
            <img src="http://www.jillmedinger.com/NCPIE/images/thumbs/shadowed/recoverythumb.png"id="1.thumb"/>
        </a> 
        <h4><a href="http://youtu.be/A30XhK8Vtmg">Ben</a></h4>
    </div>
    <div class= "thumbs">
        <img src="http://www.jillmedinger.com/NCPIE/images/thumbs/shadowed/recoverythumb.png" id="2.thumb"/> 
        <h4><a href="/NCPIE/resonator.html"> The Resonator</a></h4>
    </div>
    <div class= "thumbs">
        <a href="/NCPIE/re.html">
            <img src="images/thumbs/door2/friendsThumbs.png"id="3.thumb"/>
        </a> 
        <h4><a href="/NCPIE/re.html">RE-Covery</a></h4>
    </div>
    <div class= "thumbs">
        <a href="/NCPIE/divedeeper2.html">
            <img src="images/thumbs/door2/divedeeper2Thumb.png"id="5.thumb"/>
        </a>  
        <h4><a href="/NCPIE/divedeeper2.html"> Dive Deeper </a></h4>
    </div>
    <!--thumbsGrid close-->     
</div>

CSS:

.thumbs {
    float:left;
    width:100px; 
    height:100px;
    margin-right:12px;
    margin-bottom:0;
    border:0;
    padding:0;
}
#thumbsGrid {
    float:left;
    width:500px;
    min-height:216px;
    margin-left:110px;
    border:0;
    padding-right:40px;
    background: black;
}
.thumbs h4 a {
    color: #FFF;
}

Answer 1

它与 .thumbs 上的 filter 有关。最简单的解决方案是将 position: relative 设置为 h4 作为 this fiddle shows .
