flex幾種多列布局

基本的等分三列布局

.container{
        display: flex;
        width: 500px;
        height: 200px;
    }
    .left{
        flex:1;
        background: red;
    }
    .middle{
        flex:1;
        background: green;
    }
    .right{
        flex:1;
        background: blue;
    }
<div class="container">
    <div class="left"></div>
    <div class="middle"></div>
    <div class="right"></div>
</div>

        display: flex;
        height: 300px;
