Bootstrap 5 网格不等于 12 列宽
Bootstrap 5 Grid Not Equaling 12 Column Width
如果我错了请纠正我，bootstrap 网格由 12 列组成（宽度方向 [根据 Grid System Documentation]）。如果我在流体容器中指定两列（宽度始终为 100%），第一列为 col-md-3，第二列为 col-md-9。为什么我的第二列总是被推到第一列下面？不应该并排吗？

您在 container-fluid div 之后缺少行 class 的 div。这将帮助您处理您的案件。在Bootstrap中，在一个容器之后，如果你会用到cols，最好把它们包成一行class div.

检查你的 DIV 标签，你漏了一个，从一行开始，把列放在行内。
如果我错了请纠正我，bootstrap 网格由 12 列组成（宽度方向 [根据 Grid System Documentation]）。如果我在流体容器中指定两列（宽度始终为 100%），第一列为 col-md-3，第二列为 col-md-9。为什么我的第二列总是被推到第一列下面？不应该并排吗？
