html - Firefox绝对定位失败

Question

我的网站 http://cynthiawoodyardlandscapedesign.com/ 存在一些仅在 Firefox 中存在的问题。

当单击主页上的图像时，两侧出现的允许用户更改图片的箭头位于页面顶部。持有箭头的 div 的高度应该为 100%，我什至添加了 !important到CSS。只有 Firefox 无法正确显示这一点。

我的 CSS ( http://cynthiawoodyardlandscapedesign.com/css/main.css ):

#sheet {
    width: 100%;
    height: 100%;
    position: fixed;
    overflow: hidden;
    top: 0;
    left: 0;
    background-color: rgba(0,0,0,0.8);
    display: table;
    z-index: 150;
}
#popover {
    margin: auto;
    background: rgba(0,0,0,0);
    text-align: center;
    padding: 10px;
    border: 1px solid black;
    position: relative;
    display: table-cell;
    vertical-align: middle;
}
#popover-image {
    height: 70%;
    border: 10px solid white;
}
#exit {
    position: absolute;
    top: 50px;
    color: white;
    font-size: 20px;
    font-weight: bold;
    width: 100%;
    text-align: center;
    z-index: 300;
    font-family: sans-serif;
}
#next-image, #previous-image { cursor: pointer; background:  transparent; }
#next-image::-moz-selection, #previous-image::-moz-selection,
#next-image::selection, #previous-image::selection { background: rgba(0,0,0,0); }
#leftArrow, #rightArrow {
    width: 20%;
    height: 100% !important;
    position: absolute;
    z-index: 200;
    display: table;
    background: transparent;
    top: 0;
}
#leftArrow { left: 0; } #rightArrow { right: 0; }
#next-image {
    display: table-cell !important;
    vertical-align: middle;
    margin: 0 auto;
    text-align: center;
    line-height: 50px;
    font-size: 50px;
    -webkit-text-stroke: 1px black;
    -moz-text-stroke: 1px black;
    height: 50px;
    width: 50px;
    color: white;
}
#previous-image {
    display: table-cell !important;
    vertical-align: middle;
    margin: 0 auto;
    text-align: center;
    line-height: 50px;
    font-size: 50px;
    -webkit-text-stroke: 1px black;
    -moz-text-stroke: 1px black;
    height: 50px;
    width: 50px;
    color: white;
}

我的 HTML (http://cynthiawoodyardlandscapedesign.com/default.php):

<div id="sheet">
    <div id="exit">Exit</div>

    <div id="popover">
        <div id="leftArrow"><div id="previous-image" onclick="previous()">&laquo;</div></div>

        <img src="watermark.php?src=images/main1.jpg&x=0&y=420&opactity=50" id="popover-image" onclick="close()" />

        <div id="rightArrow"><div id="next-image" onclick="next()">&raquo;</div></div>

    </div>

</div>

我尝试过的所有其他浏览器(IE 除外；我使用的是 Mac)都能正确显示该页面。

编辑:我遇到了更多 Firefox 问题。

页面http://cynthiawoodyardlandscapedesign.com/photography.php显示 <td> 中的许多图片标签和 img 之后但在</td>之前有一个具有绝对位置的跨度，top: 10px;在每个浏览器(甚至 IE8!!)上它都不能正常工作。

我的 HTML 页面:

<table id="photos">
                <tr>
                    <td><img src="images/photo-thumbs/garden.jpg" /><span>Gardens</span></td><td><img src="images/photo-thumbs/trees.jpg" /><span>Trees</span></td><td><img src="images/photo-thumbs/shrubs.jpg" /><span>Shrubs</span></td><td><img src="images/photo-thumbs/perennials.jpg" /><span>Perennials</span></td>
                </tr>
                <tr>
                    <td><img src="images/photo-thumbs/annuals.jpg" /><span>Annuals</span></td><td><img src="images/photo-thumbs/tropicals.jpg" /><span>Tropicals</span></td><td><img src="images/photo-thumbs/bulb.jpg" /><span>Bulbs</span></td><td><img src="images/photo-thumbs/containers.jpg" /><span>Containers</span></td>
                </tr>
                <tr>
                    <td><img src="images/photo-thumbs/fruit.jpg" /><span>Fruit</span></td><td><img src="images/photo-thumbs/animals.jpg" /><span>Creatures</span></td><td><img src="images/photo-thumbs/people.jpg" /><span>People</span></td><td><img src="images/photo-thumbs/travel.jpg" /><span>Travel</span></td>
                </tr>
</table>

#photos td {
        width: 192px;
        height: auto;
        position: relative;
        border-right: 5px solid transparent;
    }
    #photos td img { width: 100%; border: 1px solid gold; }
    #photos td span {
        position: absolute;
        top: 10px;
        left: 0;
        width: 100%;
        text-align: center;
        background: rgba(0,0,0,0.4);
        padding-top: 2px;
        padding-bottom: 2px;
        color: #f0f0f0;
        font-weight: bold;
        font-family: "Source Sans Pro", sans-serif;
        display: none;
    }

Answer 1

这是第二部分的答案:跨度位置的悬停问题。它工作正常，请参阅我在 html、css 和 jquery 代码中所做的以下更改。如果我遗漏了什么，请告诉我。

代码: http://jsfiddle.net/brNdq/1/

工作演示: http://jsfiddle.net/brNdq/1/embedded/result/

HTML:

<table id="photos">
      <tr>
        <td><div class="img_container"><img src="http://cynthiawoodyardlandscapedesign.com/images/photo-thumbs/garden.jpg" /><span>Gardens</span></div></td>
        <td><div class="img_container"><img src="http://cynthiawoodyardlandscapedesign.com/images/photo-thumbs/trees.jpg" /><span>Trees</span></div></td>
        <td><div class="img_container"><img src="http://cynthiawoodyardlandscapedesign.com/images/photo-thumbs/shrubs.jpg" /><span>Shrubs</span></div></td>
        <td><div class="img_container"><img src="http://cynthiawoodyardlandscapedesign.com/images/photo-thumbs/perennials.jpg" /><span>Perennials</span></div></td>
      </tr>
      <tr>
        <td><div class="img_container"><img src="http://cynthiawoodyardlandscapedesign.com/images/photo-thumbs/annuals.jpg" /><span>Annuals</span></div></td>
        <td><div class="img_container"><img src="http://cynthiawoodyardlandscapedesign.com/images/photo-thumbs/tropicals.jpg" /><span>Tropicals</span></div></td>
        <td><div class="img_container"><img src="http://cynthiawoodyardlandscapedesign.com/images/photo-thumbs/bulb.jpg" /><span>Bulbs</span></div></td>
        <td><div class="img_container"><img src="http://cynthiawoodyardlandscapedesign.com/images/photo-thumbs/containers.jpg" /><span>Containers</span></div></td>
      </tr>
</table>

CSS:

.img_container {
    position:relative;
}

Jquery:从 TD 中删除悬停并将其放在 .img_container 类中

<script type="text/javascript">
$(document).ready(function () {
    $(".img_container").hover(function() {
        $(this).children('span').fadeIn('medium');
    }, function () {
        $(this).children('span').fadeOut('fast');
    });
});
</script>
