"nthlink" refers to the idea of targeting the nth anchor element(s) in a document or container to style, analyze, or attach behavior. While not a formal web standard, the pattern combines CSS structural selectors and small JavaScript helpers to give designers and developers fine-grained control over link presentation and interaction patterns. Why nthlink? Practical situations often call for highlighting periodic links: promote every third article in a list, visually separate sponsored links, A/B test link treatments, or throttle click behavior on a repeating list of external references. nthlink makes it easy to identify links at a predictable interval and apply consistent logic without manually tagging each element. Core techniques - Pure CSS: Use structural selectors when links are direct children of a container. Example: container a:nth-child(3n) applies styles to every third child link. Drawback: nth-child counts all element types, so markup must be predictable. - nth-of-type: If the container includes only anchor elements or consistent element types, a:nth-of-type(3n) works better. - JavaScript selection: For complex DOMs, use document.querySelectorAll('a') to build a list and iterate with modular arithmetic: if ((i + 1) % n === 0) { /* apply class or behavior */ }. Lightweight JS pattern - Select once and cache: const links = container.querySelectorAll('a'); for (let i=0;i
