与图象的3D作用作为另一个图象的背景 [英] 3D effect with image as a background of another image

问题描述

我想为图片添加3D效果，最终结果应该是
，如下所示：（在Photoshop中说明）

< img src =https://i.stack.imgur.com/Z6ivo.pngalt =我要找的结果>

尝试使用css3属性 box-shadow
，但它不提供真正的3D效果，如下图所示：
（我知道我可以将模糊设置为0并改变两侧，但是你可以看到 - 角落在我想实现的 shadow result）

找不到一个只有CSS的解决方案后，我创建了下面的图片，并将其设置为图片本身的背景。 p>

 
 code> .framed {
 background-image：url（'http://www.6pix.co/images/shadow-3.png'）; 
 padding-left：2.9％; 
 padding-bottom：2.9％; 
 background-size：cover; 
} 
  

I'm trying to add a 3D effect to an image, the final result should look like the following: (illustrated in Photoshop)

I've tried playing with the css3 property box-shadow but it doesn't provide a real 3D effect, as you can see in the following image: (I know I can set blur to 0 and change sides, but as you can see - there's a difference in the corners between what I'm trying to achieve to the box-shadow result)

After not finding a only-CSS solution - I've created the following image and set it as a background of the image itself.

JSFIDDLE * Please notice - I'm using the bootstrap framework.

HTML

<img src="" class="img-responsive framed">

CSS

.framed{
background-image: url('URL-OF-THE-FRAME');
padding-left: 5px; //The thickness of the "line"
padding-bottom: 5px; //The thickness of the "line"
background-size: cover;
}

.img-responsive{
display: block;
max-width: 100%;
height: auto;
}

Which gives the result I was looking for - but, if you re-size the window (try enlarging the result's window in the jsfiddle) a distance between the image and the frame is being created.

Should I try another tactic or am I missing here something?

解决方案

You need to use percent padding so it addapts to the size of the image/container when window is resized.

DEMO

CSS :

.framed{
    background-image: url('http://www.6pix.co/images/shadow-3.png');  
    padding-left: 2.9%;  
    padding-bottom: 2.9%;  
    background-size: cover;  
}
