鼠标悬停卡片scale缩放时右侧图片偏移问题求助

核心问题分析 #

1. 边框尺寸突变：hover时新增3px边框，导致卡片整体尺寸变大，内部flex布局的space-between会重新分配空间，底部图片因此被挤压上移
2. 缩放渲染偏移：默认缩放原点虽为中心，但元素布局的微小变化在缩放时会被放大，进一步加剧视觉上的偏移感

修复方案 #

• 给卡片默认添加透明边框，hover时仅修改边框颜色，彻底避免尺寸突变
• 显式设置transform-origin: center，确保缩放始终以卡片中心为基准
• 固定内部容器的布局规则，防止空间分配异常

HTML 部分（保持原结构即可）

额外优化点 #

• 父容器添加gap和padding，防止卡片缩放时互相重叠
• 左侧图片设置object-fit: cover，确保固定尺寸内保持比例
• 底部图片容器添加flex-shrink: 0，避免被布局压缩
