sitewide

Sitewide is an adjective used in web development and content management to describe features, content, or settings that apply across an entire website rather than to individual pages or sections. The term emphasizes scope that spans the whole site, often implemented through global templates, stylesheets, or configuration settings so that a single change affects all pages.

Spelling variants include sitewide and site-wide; hyphenated forms appear in some style guides and documentation.

Common uses include sitewide notices or banners (a message shown on every page), sitewide promotions or discounts in ecommerce, and sitewide navigation or footers produced by global templates. In technical contexts, sitewide changes may involve applying styles or scripts across the whole site via a global CSS file or common header/footer templates. In content management systems, sitewide settings can be adjusted from a central administration area and propagate to all content. In multi-site deployments, sitewide settings may apply to all sites in a network or to all sites sharing a common configuration.

Considerations include the impact on consistency and performance, accessibility, and the risk of overextending changes to pages where they are not needed. Proper scoping and testing help ensure that sitewide features remain unobtrusive and maintainable.
