Fancy Inset CSS Image Borders | Evan Byrne’ Writings
Before

After

The HTML Markup
In a perfect world we would only use a single img tag with a class attribute. This is not a perfect world. Because the img tag does not support the CSS pseudo-element :after, we have to wrap our image in a span.
<span class="fancy">< img src="dingo.jpg" /></span>
The CSS
The first step is to apply a simple reset to our span and img tags.
span,img{padding:0;margin:0;border:0;}
Next, we style the wrapper element.
.fancy{
position:relative;
display:inline-block;
font-size:0;
line-height:0;
}
.fancy:after{
position:absolute;
top:1px;
left:1px;
bottom:1px;
right:1px;
border:1px solid rgba(255,255,255,0.5);
outline:1px solid rgba(0,0,0,0.2);
content:&quot; &quot;;
}
