Safari 中的 Flexbox 行换行问题

Question

我有一个动态填充博客文章的页面，我正在使用 Bootstrap 和 flex 将它们在网格中对齐。这在最新版本的 Chrome、Firefox 和 IE11 中运行良好，但在 Safari 版本 8 中不起作用。在 Safari 中，第一行过早地包裹一个盒子，但其他行包裹得很好，这在顶行的末尾。

See jsfiddle here

CSS：

.flex-row {
    display: -webkit-flex;
    display: flex;
    -webkit-flex-direction: row;
    -webkit-flex-wrap: wrap;
    flex-direction: row;
    flex-wrap: wrap;
}
.single-post {
    padding: 50px 0 0;
    border: 1px solid #000;
    margin-bottom: 10px;
}
.posts__content-section {
    padding: 20px;
}
.button--more {
    padding: 5px;
    text-transform: uppercase;
    color: #fff;
    background: #000;
    font-size: 12px;
}

HTML（为测试添加随机值）：

<div class="container">
    <div class="row flex-row">

        <!-- post -->
        <div class="col-lg-3 col-sm-4 col-xs-3 single-post">

Answer 1

嗯，我觉得很傻。我只需要将flex-row 放入一个包含所有single-post 框的新div 中。 See updated jsfiddle here
