一般情况下我们通过设置类名就可以改变元素的样式，但涉及到动画部分，就一定需要设置内联样式了，因此有了ms-css。*ms-css*的用法为ms-css-样式名="样式值"， 如ms-css-width=”prop”(会自动补px)，ms-css-height=”{{prop}}%”, ms-css-color=”prop”, ms-css-background-color=”prop”, ms-css-font-size=”{{prop}}px”。细细联想，ms-css与ms-class的旧风格、ms-data、ms-attr的用法相仿，属性名接第三个参数作为name，属性值作为value。

ms-css已经在内部帮你处理好兼容问题，如opacity在旧式IE下用滤镜替换， tranform的私有前缀添加什么的。 最后要注意一点，属性值不能加入CSS hack与important!
