` elements green.
+
+## Common Selectors
+
+- `element` (e.g., `h1`, `p`): Targets all elements of that type
+- `.class`: Targets elements with a specific class
+- `#id`: Targets a unique element with an ID
+- `*`: Targets everything
+
+Example:
+
+```css
+.highlight {
+ background: yellow;
+}
+#main-title {
+ font-size: 2em;
+}
+```
+
+:::info
+You can combine selectors for more power: `div p` targets all `
`.

+
+Great start! Now, let’s learn the most important Git commands. These are your tools for saving, viewing, and sharing your work.
+
+## Common Commands
+
+- `git init`: Start a new Git repository
+- `git status`: See what’s changed
+- `git add`: Stage changes for commit
+- `git commit`: Save your changes
+- `git log`: View commit history
+
+Example workflow:
+
+```bash
+git init
+git add index.html
+git commit -m "Add homepage"
+git status
+git log
+```
+
+:::tip
+Use clear commit messages so you remember what changed!

+# Branching in Git
+
+Awesome! Now, let’s learn how to work on new features without breaking your main code. Branches are like parallel universes for your project.
+
+## What is a Branch?
+
+A branch is a separate line of development. You can experiment, then merge changes back when ready.
+
+## Common Branch Commands
+
+- `git branch`: List branches
+- `git checkout -b feature`: Create and switch to a new branch
+- `git merge feature`: Combine changes from another branch
+
+Example:
+
+```bash
+git branch
+git checkout -b new-feature
+# Make changes
+git add .
+git commit -m "Add new feature"
+git checkout main
+git merge new-feature
+```

+
+## What is GitHub?
+
+GitHub is a website for hosting Git repositories. It lets you:
+- Store your code in the cloud
+- Collaborate with others
+- Track issues and pull requests
+
+## Typical Workflow
+
+1. **Create a repository on GitHub**
+2. **Clone it to your computer**
+ ```bash
+ git clone https://github.com/your-username/your-repo.git
+ ```
+3. **Make changes, commit, and push**
+ ```bash
+ git add .
+ git commit -m "Describe your changes"
+ git push
+ ```
+4. **Open a pull request** to suggest changes
+
+:::tip
+Always pull the latest changes before you start working: `git pull`
+:::
+
+## What's Next?
+
+Time to practice! Try a mini project: [Git Projects](./projects.md).

+# Introduction to Git
+
+Welcome, version control hero! 🦸♂️ Ready to save your code and track every change? Git is your time machine for projects. It lets you record, rewind, and collaborate—so you never lose your work.
+
+Git is a tool that helps you manage changes to files over time. It’s used by developers everywhere, from solo coders to huge teams. By the end of this section, you’ll know what Git is and why it’s essential for every coder.
+
+## What is Git?
+
+- **Created in 2005** by Linus Torvalds (the creator of Linux).
+- **Distributed**: Everyone has a full copy of the project history.
+- **Tracks changes**: See who changed what, when, and why.
+
+## Why Use Git?
+
+- Undo mistakes easily
+- Work with others without overwriting each other
+- Keep a history of your project
+
+## How Git Works (Quick Analogy)
+
+Think of Git as a save system in a video game. Each time you save, you can go back to that point if something goes wrong. Git calls these saves "commits."
+
+## What's Next?
+
+Let’s get hands-on! Next: [Basic Git Commands](./basic-commands.md) to start using Git for real.

+# Git Projects
+
+Congratulations! 🎉 You’ve learned the basics of Git and GitHub. Now it’s time to practice with some real-world projects.
+
+## Project Ideas
+
+1. **Personal Website Repo**
+ - Create a GitHub repo for your website and track all changes.
+2. **Collaborative Story**
+ - Work with a friend: each person adds a chapter to a story using branches and pull requests.
+3. **Bug Tracker**
+ - Use GitHub Issues to track bugs or ideas for a project.
+
+## Tips
+
+- Commit often with clear messages.
+- Try branching for new features.
+- Share your repo and get feedback.
+
+:::tip
+Explore open source projects on GitHub to see how others use Git!
+:::
+
+## What's Next?
+
+You’re now ready to manage code like a pro! Keep practicing and explore more advanced Git features as you grow.

+
+## Accessibility
+- Always use `alt` attributes for images:
+ ```html

+ ```
+- Use semantic HTML (like `
