-webkit-linear-gradient causes 400 (Bad request) error in Safari

I'm using Compass to generate linear gradients but I'm getting a strange error indicating that Safari (Version 5.1.2 [6534.52.7]) is trying to load the vendor prefixed line as if it's a URI. Weird!

The Compass code: body { @include background-image(linear-gradient(top, #F7F7F7 0%, #FFFFFF 20%, #cccccc 57%, #dddddd 60%, #f1f1f1 80%, #FFFFFF 100%)); }

Generated CSS:

background-image: -webkit-gradient(linear, 50% 0%, 50% 100%, color-stop(0%, #f7f7f7), color-stop(20%, #ffffff), color-stop(57%, #cccccc), color-stop(60%, #dddddd), color-stop(80%, #f1f1f1), color-stop(100%, #ffffff));
background-image: -webkit-linear-gradient(top, #f7f7f7 0%, #ffffff 20%, #cccccc 57%, #dddddd 60%, #f1f1f1 80%, #ffffff 100%);
background-image: -moz-linear-gradient(top, #f7f7f7 0%, #ffffff 20%, #cccccc 57%, #dddddd 60%, #f1f1f1 80%, #ffffff 100%);
background-image: -o-linear-gradient(top, #f7f7f7 0%, #ffffff 20%, #cccccc 57%, #dddddd 60%, #f1f1f1 80%, #ffffff 100%);
background-image: -ms-linear-gradient(top, #f7f7f7 0%, #ffffff 20%, #cccccc 57%, #dddddd 60%, #f1f1f1 80%, #ffffff 100%);
background-image: linear-gradient(top, #f7f7f7 0%, #ffffff 20%, #cccccc 57%, #dddddd 60%, #f1f1f1 80%, #ffffff 100%);

Despite the error, the gradient is rendered correctly. Also there are numerous other multi-stop linear gradients throughout the page which don't cause the error. It appears that this is a Safari bug - it occurs only when the gradient is used in the . Check out some code (see the error live if you're running Safari):

  1. With error (gradient in Body Tag)
  2. No error (same gradient elsewhere)

Any ideas/solutions would be greatly appreciated.

Solution

  • Thanks @maxbeatty for checking it out on your version of Safari. Your post led me to dig in a little further, and to disable all plugins. I found that the culprit was the Safari AdBlock Plugin. Disabling it made the error go away.
