Postfolio Blocks is a free, lightweight full-site-editing (FSE) WordPress block theme for blogs, news and magazine sites, portfolios and agencies, built only from core blocks. It includes 5 one-click starter sites with demo content (Personal Blog, Online Magazine, Editorial News, Creative Portfolio, Business & Agency), 68 block patterns, 27 templates and 15 template parts: a breaking news ticker, live blog, ad slots, magazine homepages, category pages with a lead story, author pages, case study pages for portfolio work, and dedicated layouts for video, gallery, quote and audio post formats. Seven style variations, eight color palettes, six font pairings and an optional dark mode restyle the site in one click. Fonts are self-hosted, scripts load only where they are used, and every palette is designed for readable contrast. Blog tools include reading time, related and popular posts, an author box and an automatic table of contents.
