✅ Article structure - blocks-based content (paragraph, heading, quote, image, code) ✅ Rich text editor - Medium-style block editor z formatowaniem ✅ Block menu - add, convert, delete blocks ✅ Auto-resize - textareas adjust to content ✅ Draft system - save drafts, auto-save ✅ Reading time - calculate based on word count ✅ Title editing - large, serif font ✅ Publish workflow - draft → publish
W następnym ćwiczeniu dodamy reading experience i claps!
Do zobaczenia! 🚀
