Question

css

There is a certain layout of three child elements. Example https://codepen.io/Foxmind/pen/xxGYLZE

I need to select the second of two items with class item. Instead, the first one is chosen. Tell me, please, why?

Answer 1

Nothing will come of it. :nth-child :nth-of-type counts all elements of a common parent, regardless of class.
UPD :nth-of-type is tag specific and only counts elements with the tag it was applied to.
