回答by LeBen
Match labels who are the first, direct child of a div.
匹配 div 的第一个直接子代的标签。
div > label:first-child {}
Actually it would be much better if you could add some classes to your elements. Matching wide selector such as divis a bad idea for future maintainability. Changing your markup will break your style.
实际上,如果您可以为元素添加一些类会更好。匹配宽选择器div对于未来的可维护性来说是一个坏主意。改变你的标记会破坏你的风格。
