Q: What’s the difference between :nth-child() and :nth-last-child()?

The `:nth-child()` and `:nth-last-child()` pseudo-classes in CSS are used to select elements based on their position among siblings, but they count from opposite ends. `:nth-child(n)` – Selects the nth child from the start (first child is 1). `:nth-last-child(n)` – Selects the nth child from the end (last child is 1). Both can use formulas like `2n`, `2n+1`, or `3n+2` for selecting patterns of elements. /* Style every second list item from the start */ ul li:nth-child(2n) { background-color: lightblue; } /* Style every second list item from the end */ ul li:nth-last-child(2n) { font-weight: bold; } Item 1 Item 2 Item 3 Item 4 Item 5 Item 6 In this example, `:nth-child(2n)` highlights items 2, 4, and 6 from the start with a light blue background. `:nth-last-child(2n)` makes items 2, 4, and 6 from the end bold, demonstrating the difference in counting direction. Use `:nth-child()` when targeting elements from the beginning of the container. Use `:nth-last-child()` when targeting elements from the end. Combine with other pseudo-classes like `:not()` or `:first-child` for precise selections. Test with dynamic content as adding/removing elements may affect which items are selected.
