The counter-increment property sets how much the counter increments on each occurrence of a selector. Default increment is 1.
counter-increment 属性可设置每当选择器发生时记数器所增加的值。默认值为1

Note: If "display: none" is used you should not be able to increment the counter. If "visibility: hidden" is used you should be able to increment the counter.
注意：如果使用了"display:none"那么就不能够增加记数器了。如果使用的是 "visibility: hidden"那么记数器还是能够增加的。

Inherited: No
继承性：无
