html5 - 关于css伪类选择器中：nth-of-type(n) 选择器

Answer 1

:nth-of-type(n) only counts child elements of a certain type specified in the parent element
"n" is its parameter, and can be an integer value (1,2,3,4), It can also be expressions (2n+1, -n+5) and keywords (odd, even), but the starting value of parameter n is always 1, not 0. In other words, when the value of parameter n is 0, the selector will not select any matching elements.
