The Three Pillars of the Web
Modern websites are built using three core technologies. You can edit all three in the panels above:
HTML (Structure)
HyperText Markup Language defines the skeleton of your page: headings, paragraphs, and images.
Learn HTML on MDN →CSS (Style)
Cascading Style Sheets control the look: colors, fonts, layouts, and animations.
Learn CSS on MDN →JavaScript (Logic)
JS makes pages interactive. It handles button clicks, data fetching, and math.
Read JavaScript.info →Recommended Learning Resources
