同学，你好，你的代码中没有找到ava hover，不知道同学说的是哪里呢？
第二个“hover recommend时describe升起”的问题，这里不能给recommend设置hover，你的课程列表结构可以修改一下，改成如下方式会比价清晰，也比较好设置hover动作：
然后给.plan_item设置hover，让 .bottom 设置top: 50px; 。但是实现需要给plan_item设置相对定位，给bottom设置绝对定位，需要配合定位来实现。
整体是这样的一个思路，当然其他地方需要对样式稍作调整，从同学的代码中可以看出来你是有能力去实现的，加油！如果还有问题可以继续提问，也可以直接提交作业，批作业的老师也会为你做详细的解答。
如果帮助到了你，欢迎采纳！
