Sass团队创建了Compass大大提升CSSer的工作效率,你无需考虑各种浏览器前缀兼,只需要按官方文档的书写方式去写,会得到加上浏览器前缀的代码,如下:
.row { @include display-flex;}
会得到如下代码:
.row { display: -webkit-flex; display: flex;}
但是, 做为一个长期用原生CSS书写方式的CSSer,不太习惯去官方查文档,再以@include方式书写。
那么问题来了,我只能放弃高效率方式么?
其实不然, Autoprefixer能够帮助你。
其实, Autoprefixer也仅仅是PostCSS其一个最出名的插件。
来吧, 来看张图:
这样,以一种原生CSS的书写方式, 然后还可以帮你解决浏览器前缀、IE兼容、以下一代CSS书写方式兼容现在浏览器, 是不是很酷?
哦, 其实应该说更简单、更优雅, 不用查文档, 不用@include。
这个就是Twitter推出的postcss, 据说Google、阿里、Shopify, Twitter就不用说了。
