Chrome Dev Tools has had that feature (for css specifically, not transpiled languages) for years. https://developer.chrome.com/docs/devtools/workspaces/ https://developer.chrome.com/docs/devtools/workspaces/ We used to have full WYSIWYG editors in browsers as far back as the 90s (including deployment via FTP). Specialized editors just seem to have always been the preference for developers.
