A robots.txt file tells crawlers which URLs they may crawl on your site. It does not directly control indexing; for indexing control, use noindex and related mechanisms. Configure robots rules carefully to avoid blocking important content. See Access your robots.txt file. See How do I prevent specific pages from getting indexed by search engines?.

The tabindex attribute controls whether an element can receive keyboard focus and in what order. Use 0 to include an element in natural tab order and -1 for programmatic focus only. Avoid positive values because they create confusing navigation order.

A switch-style control for binary choices, indicating on/off or enabled/disabled states with immediate effect. Toggles differ from checkboxes in that they typically apply changes immediately rather than requiring a submit action. Use clear labeling so users understand what enabled and disabled states mean.

A CSS property controlling stack order when elements overlap, with higher values appearing in front of lower values. Z-index management becomes complex with many overlapping elements—establish systematic layer naming. In Framer, layer order in the sidebar determines stacking with z-index overrides available.

An XML Sitemap is a structured file that lists important URLs and metadata so search engines can crawl and index a website more efficiently.
