HTML/CSS中卡片hover效果与图片opacity调整失效问题排查

问题排查与解决方案

问题根源

图片opacity不生效的核心原因是：图片的父容器（带有opacity-40类的div）设置了透明度，opacity属性会被子元素继承，且子元素无法通过设置opacity:1覆盖父元素的透明度（子元素实际透明度为父元素透明度 × 自身透明度）。同时你当前的CSS仅针对img设置hover时的opacity，没有作用到真正控制透明度的父容器。

另外，当前hover效果中卡片和图片的位移过渡未统一，会导致动画不同步。

修复方案

将父容器的透明度设置转移到img标签上，让img自身控制初始透明度
修改CSS选择器，确保hover时能正确修改img的opacity，同时统一过渡动画
优化动画同步性，让卡片和图片的动效节奏一致

关键修改点

移除父容器的opacity-40类，将初始透明度直接设置在img元素上
给img添加transition: all 0.3s ease，确保位移和透明度变化同步
调整hover选择器为.your-card:hover .card-image img，精准定位目标元素
保持卡片上移动画不变，同时让图片的位移和透明度变化流畅联动
