Не могу разобрать с clearfix. По задумке блок div3 не должен залезать на плавающие элементы. Если ставлю отдельный блок со свойством clear: both все работает. Если делаю через псевдоэлемент (код ниже), то подпорка не срабатывает. Можете указать где ошибка?

    <!-- STYLE -->
<style>
    * {
        margin: 0;
        padding: 0;
    }
    .wrapper {
        height: 100px;
        width: 100%;
        background-color: silver;
    }
    .clearfix:after {
        content: "";
        display: table;
        clear: both;
    }
    .div1 {
        float: left;
        background-color: rgba(227,27,191,0.5);
        width: 30%;
    }
    .div2 {
        float: left;
        background-color: #A8ECFF;
        width: 40%;
    }
    .div3 {
        width: 30%;
        height: 180px;
        background-color: #50D42A;
    }
</style>
<!-- CONTENT -->
