css - Defined Edges With CSS3 Filter Blur

Question

I am blurring some images with this code

img {
  filter: blur(5px);
  -webkit-filter: blur(5px);
  -moz-filter: blur(5px);
  -o-filter: blur(5px);
  -ms-filter: blur(5px);
}

The edges of the image get blurred too though. Is it possible to blur the image, while keeping the edges defined? Like an inset blur or something?

Answer 1

You could put it in a <div> with overflow: hidden; and set the <img> to margin: -5px -10px -10px -5px;.
