How to realize the effect of logo stereo box with CSS:CSS style

Let's see how we can achieve the effect of the stereo box, and then we'll show you some good examples.
Prepare your page and pictures first, we use this picture:
we simply write HTML as this:

<div id= "Container" >

</div>
CSS styles might look like this:

Body{background: #999;}

#container {
width:960px;
Background: #fff;
margin:20px Auto;
padding:10px;
}
Here is an effect preview:
Set to relative positioning, when we position the logo, we want its position to be relative to the container, so use relative positioning:
#container {
width:960px;
Background: #fff;
margin:20px Auto;
padding:10px;
position:relative;
}
Locate it outside the box. Now all you need to do is position the logo, position it horizontally, and make it stand out from the container.

#logo {
Position:absolute;
left:-15px;
}
Now, we can see that the logo has been shown outside the box.
