There is no background-repeat-x CSS property
<http://dev.w3.org/csswg/css3-background/>. Background-repeat is one of those
properties with X, Y values that sound like they should be shorthands, but
actually are not. The CSS WG has talked a few times about whether it's useful
to expose separate properties for the -x and -y values, but in general we tend
to avoid adding new CSS properties.
