I wrote this fairly straightforward cross-browser linear gradient mixin:

@mixin gradient($from-color, $to-color) {
	background-color: mix($from-color, $to-color); /* Fallback */
	background-image: -webkit-gradient(linear, 0% 0%, 0% 100%, from($from-color), to($to-color));
	background-image: -webkit-linear-gradient(top, $from-color, $to-color); 
	background-image:    -moz-linear-gradient(top, $from-color, $to-color);
	background-image:     -ms-linear-gradient(top, $from-color, $to-color);
	background-image: -o-linear-gradient(top, $from-color, $to-color);

# Mac OS X webarchive is a binary format of a plist file. You can extract the contents manually:
#  1. convert the plist file into XML by "plutil -convert xml1 file.webarchive"
#  2. parse the resulted XML file by some XML parser
#  3. decode "WebResourceData" by Base64.decode64(data) in each key
#  4. save the decoded content into a file indicated by "WebResourceData"
# Thankfully, the plist library can take care of annoying steps 2 and 3.
