What Can You Do With HTML?

With HTML (plus a little CSS and JavaScript later) you can:

• Build websites — personal pages, portfolios, blogs, business sites, and documentation.
• Create forms — sign-ups, surveys, search boxes, checkouts — with built-in validation that works without any JavaScript.
• Publish media — images that adapt to screen size, video with captions, audio players.
• Present data — accessible tables and description lists.
• Make content findable — titles, descriptions, social previews, and structured data that search engines turn into rich results.
• Build interfaces — disclosure widgets, dialogs, and popovers built into the language, and your own reusable elements with web components.
• Write HTML email — newsletters and transactional emails (with their own quirks, covered in Level 3).
• Generate documents — many tools turn HTML into PDFs and printable reports.

You'll build smaller versions of several of these in the project lessons at the end of each level.
