你可以覆盖一个图像透明的div

我在下面的图片中运行了这个例子,这是在Flash中完成的,我想知道是否有一个类似的影响,有一个透明的框在图像的底部与文本是可能的CSS或其他什么闪光?

当然,这是一个跨浏览器的方式:

<html> <head> <style type="text/css"> div.imageSub { position: relative; } div.imageSub img { z-index: 1; } div.imageSub div { position: absolute; left: 15%; right: 15%; bottom: 0; padding: 4px; height: 16px; line-height: 16px; text-align: center; overflow: hidden; } div.imageSub div.blackbg { z-index: 2; background-color: #000; -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=50)"; filter: alpha(opacity=50); opacity: 0.5; } div.imageSub div.label { z-index: 3; color: white; } </style> </head> <body> <div class="imageSub" style="width: 300px;"> <!-- Put Your Image Width --> <img src="image.jpg" alt="Something" /> <div class="blackbg"></div> <div class="label">Label Goes Here</div> </div> </body> </html> 

这种方法不需要JavaScript,不会导致在IE中丢失ClearType文本,并且与Firefox,Safari,Opera,IE6,7,8兼容。不幸的是,它只能用于一行文本。 如果你想多行,可以调整div.imageSub divheightline-height属性,或者使用下面的代码(对CSS的修改,并且要求标签被指定两次)。

 <html> <head> <style type="text/css"> div.imageSub { position: relative; } div.imageSub img { z-index: 1; } div.imageSub div { position: absolute; left: 15%; right: 15%; bottom: 0; padding: 4px; } div.imageSub div.blackbg { z-index: 2; color: #000; background-color: #000; -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=50)"; filter: alpha(opacity=50); opacity: 0.5; } div.imageSub div.label { z-index: 3; color: white; } </style> </head> <body> <div class="imageSub" style="width: 300px;"> <!-- Put Your Image Width --> <img src="image.jpg" alt="Something" /> <div class="blackbg">Label Goes Here</div> <div class="label">Label Goes Here</div> </div> </body> </html> 

当然。

 <div style="background-image: url(image.png);" > <div style="position:relative; top:20px; left:20px;"> Some text here </div> </div> 
 <html> <body> <div style="position: absolute; border: solid 1px red"> <img src="http://www.ajaxline.com/files/imgloop.png"/> <div style="position: absolute; top:0px; left:40%; width:20%; height: 10%; background-color: gray; opacity: .80; -moz-opacity: 0.80; filter:alpha(opacity=80);"/> <div style="position: absolute; top:0px; left:40%; width:20%; height: 10%; color: white;"> Hello </div> </div> </body> </html>
