CSS在悬停时淡入

Question

当我使用CSS将鼠标悬停在某些文本上时,我正在尝试使用淡入淡出的图像.我已经应用了CSS代码,但效果没有显示出来; div出现了,但没有淡出.

此外,我意识到CSS转换并不真正适用于IE.如果有人能指出我的解决方法的正确方向,那将非常感激.(:

CSS:

.thumbnail{
position: relative;
z-index: 0;
}

.thumbnail:hover{
background-color: transparent;
z-index: 50;
}

.thumbnail span{ /*CSS for enlarged image*/
position: relative;
display: none;
color: black;
text-decoration: none;
opacity:0.0;
filter:alpha(opacity=0);
}

.thumbnail span img{ /*CSS for enlarged image*/
border-width: 0;
padding: 5px;
left: -1000px;
border: 1px solid gray;
background-color: #fff;
}

.thumbnail:hover span{ /*CSS for enlarged image on hover*/
position: relative;
display: inline;
top: -290px;
left: -25px; 
opacity:1.0;
filter:alpha(opacity=100);/*position where      
enlarged image should offset horizontally */
-webkit-transition: all 0.2s ease-in-out;
-moz-transition: all 0.2s ease-in-out;
-o-transition: all 0.2s ease-in-out;
transition: all 0.2s ease-in-out;
}

#networking {
width: 200px; 
height: 140px; 
margin-left: 360px; 
top: 115px; 
position: absolute; 
background-color: #613286; 
opacity:1.0;
filter:alpha(opacity=100); 
color: #ffffff; 
text-align:center; 
border-radius: 20px; 
-webkit-transform: rotate(14deg);
-moz-transform: rotate(14deg);
-ms-transform: rotate(14deg);
-o-transform: rotate(14deg);
transform: rotate(14deg);
}

HTML:

<div id="networking">
<a class="thumbnail" href="1.5.2experientialstudios.html#down4"><h4>Networking Lounge</h4>    
<span><img src="images/net3.jpg" width="250" /></span></a>
</div>

谢谢!

Answer 1

尝试删除显示规则:

.thumbnail span{ /*CSS for enlarged image*/
    position: relative;

    /*display: none; remove this */

    color: black;
    text-decoration: none;
    opacity:0.0;
    filter:alpha(opacity=0);
}

由于你有不透明度0,你不需要显示:无,你不能在完全不显示之间进行转换,因为它们是不同的类型.

并修改此规则:

.thumbnail:hover span { /*CSS for enlarged image on hover*/

    top: 0px; /* adjust as needed */
    left: -25px; 
    opacity:1.0;
    filter:alpha(opacity=100);/*position where      
    enlarged image should offset horizontally */
    -webkit-transition: all 0.2s ease-in-out;
    -moz-transition: all 0.2s ease-in-out;
    -o-transition: all 0.2s ease-in-out;
    transition: all 0.2s ease-in-out;
}

(悬停然后跨度可以使它有点跳跃).

我还为转换添加了ms前缀版本.在这种情况下,它显然没有用处.

对于IE9及更低版本,您可以使用jQuery淡入元素(或者只是使用vanilla JavaScript来修改setTimeout循环中的不透明度).

这就是你要追求的吗？
