如何为pseduo css calsses设置ngclass / ngstyle内联

Question

我有下面的html和css，我需要设置.tooltip：after {{item.color}}，就像我使用ngstyle为静态类设置的一样。

<div class="tooltip" ng-style="{ 'background' : item.color}" ng-class="{ 'after':  border-top: solid item.color 10px;}"</div></a>

 .time-of-year .tooltip:before {
        bottom: -22px;
        content: " ";
        display: block;
        height: 20px;
        left: 85px;
        position: absolute;
        border-color: #a9a9a9 transparent transparent transparent;
        border-style: solid;
        border-width: 11px;
    }


    /* Yellow triangle */
    .time-of-year .tooltip:after {
        border-left: solid transparent 10px;
        border-right: solid transparent 10px;
        border-top: solid #fff 10px;
        bottom: -10px;
        content: " ";
        height: 0;
        left: 99px;
        margin-left: -13px;
        position: absolute;
        width: 0;
    }
