You will also get a chance to watch pro traders trade live and learn how they manage several trades at the same time, what to do, what not to do, etc. This also includes an inclusion into a private traders group with your class so you can discuss and figure out new ways to make money together.</p>

如何在不影响我的设计和响应性的情况下修正盒子的高度？请使用我的JSFIDDLE向我展示如何修复它。
答案 0 :(得分：1)
将框设为父级并将display: flex; flex-wrap: wrap;指定给父级，每行中框的高度将匹配。
