Question

我的图片库在滚动时工作正常，虽然在图片放大的部分，我希望图库中的第一个图像自动出现在那里，此刻它只是显示一个空白框，直到你悬停在图像上。

.gallerycontainer{
position: relative;
height: 250px;
/*Add a height attribute and set to largest image's height to prevent overlaying*/
}

.thumbnail img{
border: 1px solid white;
margin: 0 5px 5px 0;
}

.thumbnail:hover{
background-color: transparent;

.thumbnail span{ /*CSS for enlarged image*/
position: absolute;
background-color: lightyellow;
padding: 5px;
left: -1000px;
visibility: hidden;
color: black;
text-decoration: none;
}

.thumbnail span img{ /*CSS for enlarged image*/
padding: 2px;
}

.thumbnail:hover span{ /*CSS for enlarged image*/
background-color: #333;
visibility: visible;
top: 0;
left: 250px; /*position where enlarged image should offset horizontally */
z-index: 50;
}

Answer 1

我不会隐藏第一张图片，但会给它一个低z-index，以便其他图像漂浮在它上面。这只适用于图像尺寸相同的情况。

HTML

<div class="gallerycontainer">
    <a class="thumbnail"><img src="Media/Images/Tardis.bmp" width="225px" height="125px" border="0" /><span class="first"><img src="Media/Images/Tardis.bmp" width="750px" height="450px"/><br />3DS Tardis Model.</span></a>
<br />
<a class="thumbnail"><img src="Media/Images/Main Station.png" width="225px" height="125px" border="0" /><span><img src="Media/Images/Main Station.png" width="750px" height="450px" /><br /></span></a>

<br />

CSS

.thumbnail:hover span, .thumbnail span.first{ /*CSS for enlarged image*/
background-color: #FFF;
visibility: visible;
top: 0;
left: 250px; /*position where enlarged image should offset horizontally */
z-index: 50;
}

.thumbnail span.first
{
    z-index: 10 !important; /*Lower z-index for first one so others appear above it */
 }

<强>更新

从你的小提琴代码中你已经错过了实现这两个重要的事情：

请注意这里的两个选择器（我的CSS代码段的第一行）：.thumbnail:hover span, .thumbnail span.first。您只有原始选择器。 - 这与“悬停”跨度
领先的“。”在.thumbnail span.first的代码中缺少 - 这会调整“第一个”范围的z-index，以便其他范围显示在其上方。

更新2

跨度需要背景颜色来遮盖第一张图像的文本。此外，如果图像具有透明度，但没有背景颜色，则会显示第一张图像。更新小提示显示了这一点。
