counters() = [ counters(name, string) | counters(name, string, list-style-type) ]{1,}
counters()类似于重复使用了counter(),来看个示例
HTML:
	- Node
		
			- Node

						counters():
ol {
	counter-reset: item;
}
li:before {
	counter-increment: item;
	content: counters(item, ".");
} 
						counter():
.test2 {
	counter-reset: item;
}
.test2 li {
	counter-increment: item;
}
.test2 li:before {
	content: counter(item)".";
}
.test2 li li {
	counter-increment: subitem;
}
.test2 li li:before {
	content: counter(item)"."counter(subitem);
} 
						从上述代码可以看出,counters()适合使用在需要继承的章节上,而counter()更适合用在独立的计数场景上。
