About

Web development teams use Sitecore Experience Accelerator (SXA) to speed up the production of websites and to reuse components, layouts, and templates across a variety of sites. SXA separates structure from design, so front-end designers, creative designers, content authors, and developers can work in parallel and you can deploy and maintain multiple sites quickly and cost effectively.
