Full site editing will change how everyone uses themes,
-and how we build them.
What is full site editing?
Full site editing is a collective term for a set of new WordPress features:
Block themes, template editing, site blocks, and global styles.
With block themes, you use blocks to create entire pages or websites.
Everything you see on a page is a block.
Templates are designs for full pages, including site header and footer.
With the template editor you can add templates to your posts and pages. You can combine existing content with new templates, and give your posts and pages individual designs, headers, and colors.
New site blocks
You can customize your pages using new site blocks, including: Site title, logo, navigation, post title, featured image, date, categories and tags.
A new theme configuration file for developers
Theme developers can use the new configuration file with both classic themes and block themes. With the theme.json file, you can define default block settings, content width, fonts and colors, and drastically reduce the CSS needed to create themes.
