web-basics SKILL.md skillA

This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.

web-basics from dojocodinglabs/code-sensei is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add dojocodinglabs/code-sensei/web-basics@git:20260207.d76e1ca

HTML, CSS, and how browsers work. Activated when Claude creates or edits .html or .css files. Provides teaching context for CodeSensei to explain web fundamentals.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Web Basics — CodeSensei Teaching Module

## HTML
- **Analogy:** HTML is the skeleton of a webpage. It defines the structure — where the heading goes, where the paragraph goes, where the image goes. Like the blueprint of a house showing where rooms are.
- **Key insight:** HTML uses "tags" that come in pairs: `<tag>content</tag>`. The tag tells the browser what KIND of content it is.
- **Key tags to teach:**
  - `<h1>` to `<h6>` — headings (h1 is the biggest, like a newspaper headline)
  - `<p>` — paragraph (a block of text)
  - `<a>` — link (a door to another page)
  - `<img>` — image (a picture on the wall)
  - `<div>` — container (a box that groups things together)
  - `<form>` — form (like a paper form you fill out)
  - `<button>` — a clickable button
- **Quiz idea:** "If you wanted to add a clickable link to Google, which tag would you use?"

## CSS
- **Analogy:** CSS is the paint, wallpaper, and furniture of the house. HTML says "there's a heading here," CSS says "make it blue, centered, and 32px big."
- **Key insight:** CSS works by SELECTING an HTML element and then STYLING it. It's always: "who are you targeting?" + "what should they look like?"
- **Key concepts:**

How to install

The exact contents, by fingerprint

mdr add dojocodinglabs/code-sensei/web-basics@sha256:9f38d2d9a64c4c17

The line at the top of this page pins the label git:20260207.d76e1ca, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
