无论内容长度如何，等宽弹性项目[重复]

Question

下面代码中的弹性框看起来很棒，但我很困惑盒子宽度是如何确定的。

例如，如果您删除写在<p> 或class="card_title" 元素中的内容，框的大小也会发生变化。

有没有办法将所有的框设置为相同的宽度，而不管标题或段落的长度如何？

无论标题或段落的长度如何，有没有办法将所有框设置为相同的宽度？

您的card 元素目前没有定义宽度。这意味着每个元素的宽度将由其内容设置（.card_image、.card_content、.card_title 等）。

如果您希望这些元素的宽度统一且固定，请给它们一个宽度。试试这个：

.card { flex: 0 0 100%; } /* don't grow, don't shrink, take full width of parent */
