HTML
The skeleton of every web page.
What is HTML?
HTML (HyperText Markup Language) defines the structure of a web page — headings, paragraphs, buttons, images. Every website is ultimately HTML. Vibe coding tools generate it for you, but knowing what it is helps when reading error messages.
HTML uses tags wrapped in angle brackets: <h1> for headings, <p> for paragraphs, <button> for buttons. The browser reads these tags and displays the visual elements.
In Vibe Coding
When Lovable or Cursor generates a button or a heading, it's writing HTML underneath. You almost never write HTML directly in vibe coding — the AI handles it. But understanding that everything on screen is HTML helps when debugging.
Example
For example: When your page has a heading, the HTML is <h1>Welcome to My App</h1>. When it has a button, it's <button>Click Me</button>. The browser reads these tags and shows the visual elements.
Why this matters
This matters because HTML appears repeatedly when building, deploying, debugging, or connecting services in vibe coding workflows.
When you'll hit this in practice
You will usually run into HTML when working on Tutorials.
