如何让按钮紧邻居中的Bootstrap容器？

问题分析 #

你当前代码里的d-flex justify-content-center会让左按钮容器、中间container、右按钮容器这三个子元素在水平方向均匀分布，导致按钮和container之间出现间隙，无法实现紧贴效果。

解决步骤 #

1. 调整外层flex对齐逻辑：移除外层div的justify-content-center类，保留d-flex，让子元素默认按顺序排列
2. 实现container居中并紧贴按钮：给中间的container添加mx-auto类，利用自动左右margin让container居中，同时挤压左右按钮容器紧贴其边缘
3. 固定按钮容器尺寸：给左右按钮容器添加flex-shrink-0类，防止按钮被压缩变形

补充说明 #

• mx-auto是Bootstrap内置类，用于设置左右margin为auto，实现元素在父容器中的水平居中
• flex-shrink-0确保按钮容器不会因空间不足被压缩，保持按钮正常显示尺寸
• 移除justify-content-center后，flex容器子元素默认从左到右排列，配合mx-auto即可让中间container居中，同时左右按钮紧贴其边缘
