为什么nth-child(n)
在这里不起作用?可以在HTML
中添加更多子级,但是我认为这不是在nth-of-type(1), nth-of-type(2)......, nth-of-type(10)
中使用CSS
添加相同规则(相同代码)的好方法。所有子项都包含相同的规则,那么为什么不在一个选择器中提及这些规则,而不是多次添加相同的规则?
我已经改变
nth-of-type(1), nth-of-type(2)...... , nth-of-type(10)
到
nth-child(n)
在下面的示例中,如果我对nth-child(n)
使用一个规则,则选项卡内容将被弄乱,选项卡将不起作用:

答案 0 :(得分:1)
确定,nth-child(n)
无法正常工作(语法上正确的nth-child(1n+0)
或nth-of-type(1n+0)
也无效)。 (An+B
的意思是“每第n个兄弟姐妹”,但是您的代码试图将类型input.tab
的第一个兄弟姐妹与类型div.tab_content
的第一个兄弟姐妹完全匹配或将第二个{{1 }}精确到第二input.tab
,依此类推-并非如此,就像您使用div.tab_content
一样(后一种语法选择了多个同级,而不是一个-事实表达式在选择器中出现两次并不意味着仅当An+B
两次出现时该表达式都适用。
对于您要执行的操作,我看不到任何“干净”的解决方案。您可能需要完全重新考虑该策略,并使用不同的文档结构仅通过一个选择器即可获得所需的内容,但是,如果您将一个规则与多个逗号分隔的选择器一起使用,则仍然可以进行大幅简化,例如:
n
