NOT SURE -epub-caption-side // discussion here: http://lists.w3.org/Archives/Public/www-style/2013Aug/0430.html -epub-hyphens // all these properties are available in unprefixed form -epub-text-orientation // in modern browsers. i have no idea if epub readers -epub-text-transform // actually implement them. honest question: how many -epub-word-break // people are writing CSS targeting epub readers? -epub-writing-mode -moz-text-size-adjust // text-size-adjust only implemented in mobile safari, -webkit-text-size-adjust // where it's buggy. property is "at risk" in the spec // and the entire spec is at risk. still, i'm taking // it out of illegal and simply not highlighting it // for now
