Turns out I just needed the *`-webkit-`* prefix (although I don't see it in this list of [vendor prefixes][1])





    .clip-me {           /* top, right, bottom, left */
      -webkit-clip-path: inset(0px 50px 50px 0px); 
              clip-path: inset(0px 50px 50px 0px); 
    }



    <img class="clip-me" src="http://i.stack.imgur.com/MnWjF.png" width="100">



Update as of **Chrome 55**, clip-path without the vendor prefix is now supported, but many other browsers still require using `-webkit-clip-path` so it's safer to include it for now.  

Here's a snapshot of [CanIUse][2] (as of 2017), with the additional details in the top right corner of partial support browsers often indicating the need for the *`-webkit-`* prefix

I'm trying to use the CSS property [`clip-path`][1], but I get an `Invalid property value` error in Chrome.

Here's a small demo:





    .clip-me {  
      clip-path: inset(0px 50px 50px 0px); /* top, right, bottom, left */
    }




    <img class="clip-me" src="http://i.stack.imgur.com/MnWjF.png" width="100">

*Note*: This is different from this question on [clip-path does not work with chrome][4], because it's specifically asking about how to apply clip path using SVG (not CSS)

According to Can I Use, it [should work in chrome][5].
