ie hack 兼容完美解决方案(前端网备份)

hack 速查表
思路:

@media screen and (min-width:0\0) and (min-resolution: +72dpi) {
    /*IE9+ CSS*/
    .carController {
        width: 500px;
    }
    .el-switch {
        width: 300px !important;
    }
}
@media all and (-ms-high-contrast: none), (-ms-high-contrast: active) {
    .carController {
        width: auto !important
    }
}

比如上面是之前人写的ie向上兼容方案，结果ie11出了问题不兼容,然后下面一条写的是ie10向上兼容方案，完美解决
