列没有保留边距

twitter-bootstrap css html

MK-DK · 技术社区 · 7 年前

我正在使用Bootstrap 3.3.7。我不明白为什么我的小栏目没有大栏目的边距。 See the demo here 是的。

我有一个 10px 列之间的边距。

外汇。第一行有以下列: 600x410px - 600x200px 300x200px 是的。

所以 200px + 200px + 10px margin = 410 height 是的。所以我给了大柱子一个高度 410px 是的。

那他们为什么不结盟呢?

配置 .img-responsive { height: 100%; } 而不是 .img-responsive {width:100%; } . 请检查下面的工作示例。希望有帮助:)

根据建议在小屏幕上设置宽度: @media (max-width: 768px) { .img-responsive { width: 100%; } }
