將上述單一html檔案修改成. vite + vie3 + ts 其他功能一率不變，資料動態傳入，使用 props
本文解答了关于HTML中span标签使用的问题，解释了span标签为何不需要类名以及如何正确设置CSS样式。
这种输出为什么是错的啊？

2016-04-08不要span中的类标签
span不用再起名字了
.first{border:1px solid red;}
span的作用其实就是为了在css中来设定样式的，所以不用类标签了。另外选择器>表示子选择器。
1px少了分号；
不会报错啊，后面一个span标签里的内容 会有 1像素的 红色边框。 .first>span {}的意思是 使class名为first下的子元素span加入CSS样式。
