autoprefixer没有添加web-kit前缀

可用。所有市佔>1%的browsers的最新兩個版本都不用prefix。

Autoprefixer utilizes the most recent data from Can I Use to add only necessary vendor prefixes.

.example {

      box-sizing: border-box; /* Ch, Saf 5.1+, IE 8+, Op 9+  */

}

Global 97.61%
unprefixed: 96.6%

•Chrome has problems selecting options from the select element when using box-sizing: border-box and browser zoom level is less than 100%.

•IE 8 ignores box-sizing: border-box if min/max-width/height is used.

•IE9 will subtract the width of the scrollbar to the width of the element when set to position: absolute / fixed , overflow: auto / overflow-y: scroll

•Safari 6.0.x does not use box-sizing on elements with display: table;

•Android browsers do not calculate correctly the dimensions (width and height) of the HTML select element.

•In IE8, the min-width property applies to content-box even if box-sizing is set to border-box.

Edit:

那些內嵌webview的app都是在用android的原生browser，但是我找不到官方的版本列表可用，不过android上了5以后，原生的webview变成可独立於android的可升级版本system apk叫"Android System WebView"所以比较不用担心版本落后，建议你去下载genymotion直接跑原生的Browser app去测试一下。

我只找到坊间android/webkit的列表，也可以參考google chrome的。
