due to Albert's support request I had a closer look at the vendor prefixed CSS properties we currently have in core.css:
- -moz-border-radius
- -moz-box-sizing
- -webkit-linear-gradient
- -moz-linear-gradient
- -ms-linear-gradient
- -o-linear-gradient
So I suggest we remove all these vendor-prefixed CSS properties from the stylesheet for XH 1.6.4 (perhaps even linear-gradient will be recognized by some of the mobile browsers then). That will save some bandwith, and will avoid warnings of the W3C validator.
