nth-child builder
Build :nth-child(), :nth-of-type(), and :nth-last-child() selectors visually — see which of the first 24 items match.
How to use
- Pick a pattern: odd, even, every-nth, index, an+b, or a range.
- Choose the pseudo-class.
- Copy the selector; the grid shows what it hits.
What it supports
Indexes and ranges 1–10,000, coefficients ±1,000; preview covers the first 24 items. Selector text only — :nth-child accepts more exotic syntax than the builder emits.
