Bootstrap 4列内带min-width元素实现横向滚动且不溢出问题咨询

修复方案 #

问题根源 #

overflow-x属性仅能控制当前容器内部内容的溢出展示规则，你将该属性加在了设置了min-width:1000px的内容容器上，内容容器本身宽度会被min-width撑到1000px，直接顶开外层col-4列容器，最终导致布局重叠、内容溢出到列外。

调整方法 #

调整属性配置的层级即可：

• 给外层带黑色边框的col-4列容器添加overflow-x: auto属性，限制列容器内内容超出列宽时滚动展示
• 移除橙色内容容器上的overflow-x: scroll属性，仅保留min-width配置

修正后核心代码 #

<!-- 仅修改第一列的配置即可 -->
<div style="border: solid 1px black;overflow-x: auto" class="col-4">
  Col container 1
  <div style="min-width: 1000px;border: solid 1px orange">Col content 1</div>
</div>

修改后列容器宽度会严格遵循Bootstrap网格规则占屏幕宽度的1/3，内部内容超出列宽时会自动在列容器内部展示横向滚动条，不会溢出到列外，也不会和其余两列发生布局重叠。
