Comment (by Jayjdk):

 This is a list of all properties and selectors with prefixes in the Twenty
 Thirteen style.css. I haven't yet looked into which one that can be
 removed.

 == Properties with prefixes: ==

 `text-size-adjust`
 * webkit
 * ms

 `hyphens`
 * webkit
 * moz
 * ms
 * unprefixed

 `appearance`
 * webkit

 `box-sizing`
 * webkit
 * moz
 * ms
 * unprefixed

 `font-smoothing`
 * webkit

 `linear-gradient`
 * webkit
 * moz
 * ms
 * o
 * unprefixed
 * Old IE

 `transition`
 * webkit
 * moz
 * o
 * unprefixed

 `calc`
 * webkit
 * unprefixed

 `transform`
 * webkit
 * moz
 * ms
 * o
 * unprefixed


 == Selectors with prefixes: ==

 `search-decoration`
 * webkit

 `focus-inner`
 * moz

 `placeholder`
 * webkit
 * moz
 * ms


 == Properties without prefixes: ==

 `box-shadow`
 * Unprefixed version is not supported in Android 3.0 and older + iOS
 Safari 4.3 or older
 * The only place the prefix ''might'' be needed as I see it is in `.blog
 .format-aside:first-of-type, .single .format-aside:first-of-type` as it's
 used to create a separation between aside posts and the navigation


 == Notes: ==

 * `-moz-placeholder` is there twice
 * `box-sizing: border-box;` (and all the prefixes) is referenced 18-19
 times

 What about using the universal selector instead? See

 {{{
 *
         -webkit-box-sizing: border-box;
         -moz-box-sizing:    border-box;
         -ms-box-sizing:     border-box;
         box-sizing:         border-box;
 }
 }}}
