🧱 Horizontal Blocks Plugin

Bring Notion-style layouts with blocks side-by-side, resizable markdown blocks that support full Obsidian syntax including images, embeds, and internal links.

✨ Features

• 🔲 Side-by-side markdown blocks using horizontal / hblock code block
• 📏 Resizable columns with a draggable divider
• 🧠 Dynamic layout — support for 2 or more columns using --- separator
• 🖼️ Auto-scaling images inside blocks
• 💾 Block width persistence — remembers layout when you return
• Live editing for page/section embeds within blocks, with reduced extra spacing for a cleaner look.
• Styling settings tab: tweak divider (color, thickness, opacity, style), block backgrounds/borders, padding and gaps, toolbar visibility, and theme-aware colors — all applied live via CSS variables.
  • Also includes text color option for block content.
  • Title text color for block headers.
• Per-block toolbar inside each column: width +/- controls, and per-block background/text color pickers with instant updates and persistence.
  • Right-click any block for quick visibility toggles (toolbar, borders, alternating shading).

⚠️ WARNING
Please refrain from entering tasks directly within the Horizontal code block.

The Horizontal function operates based on the code block. In Obsidian, text within a code block is treated as plain text. Consequently, if you input tasks inside a code block, neither the tasks plugin nor the dataview plugin will be able to recognize them.

🚀 Examples

Code 1:

```horizontal  
### Block 1  
This is the left block.  
---
### Block 2  
This is the right block.  
```

🎨 Styling Settings

You can customize the layout appearance globally without editing CSS:

• Divider: color, thickness (1–5px), opacity, and style (solid | dashed | dotted | transparent); hover accent and drag highlight.
• Blocks: background color, optional alternating shading (zebra), show/hide borders, border radius, border thickness.
  • Text color for content inside blocks.
  • Title text color for block headers.
• Spacing: inner padding (0–32px) and gap between blocks (0–24px).
• Toolbar: global visibility toggle for optional .hblocks-toolbar areas.
• Theme-aware: auto-inherit theme colors instead of custom picks.

Find it under Obsidian → Settings → Community Plugins → Horizontal Blocks – Styling.

All options apply via CSS variables/classes, so themes/snippets can override them; changes apply live without restart.

Toolbar Controls

• Width +/-: Nudge the current block’s width by small steps; changes are saved.
• Background: Per-block background color picker (overrides global background).
• Text color: Per-block foreground color picker (overrides global text color).

🤝 Contributing

Contributions are welcome! Whether it's a bug fix, a new feature, or a UI improvement — here's how to get involved.

Getting Started

1. Fork the repository and clone your fork locally.
2. Install dependencies:

   npm install
   

3. Start the dev build (watches for changes):

   npm run dev
   

4. Link to your Obsidian vault for testing — copy main.js, manifest.json, and styles.css into your vault's plugin folder:

   <vault>/.obsidian/plugins/horizontal-blocks/
   

   Reload Obsidian or use the Reload App Without Saving command to pick up changes.

Submitting a Pull Request

1. Create a focused branch for your change:

   git checkout -b feature/your-feature-name
   

2. Keep commits atomic and write clear commit messages (e.g. fix: correct font size in block content).
3. Make sure npm run build passes without TypeScript errors before opening a PR.
4. Open your PR against the main branch. Include a clear description of what changed and why.
5. Reference any related issues in the PR description (e.g. Closes #12).

Code Style Guidelines

• This project is written in TypeScript. Keep type annotations explicit.
• Follow the existing patterns for StyleSettings when adding new styling options — add the field to the interface, set a default in DEFAULT_STYLE_SETTINGS, wire it up in applyStylingVariables(), and add a toggle/picker in HBlockStylingSettingTab.
• Avoid hardcoding paths, user-specific directories, or environment-dependent commands in package.json scripts.

👏🏼 Support

Have you found the Horizontal Blocks plugin helpful, and want to support it? I welcome donations to support future development efforts. However, I typically do not accept payments for bug bounties or feature requests, as financial incentives can create stress and expectations that I prefer to avoid in my hobby project!
