title: Blur borders on image via css
body: <p>I'm trying to do something like this:</p>
  
  <p><img src="https://imgur.com/9lsia8r.png" alt="example"></p>
  
  <p>I think it could be done using background image and another image (mask) above it with a transparent center. But is it possible to do the same with pure css?</p>
