BigRichTextBox

A tiny, distraction-free online rich text box — inspired by bigtextbox.com, but built for rich text.

Use it online

• Live app:
  • https://qoyyuum.github.io/bigrichtextbox/index.html

Open the link and start typing.

What this is

BigRichTextBox is a single static web page that gives you a large, clean writing surface.

You can:

• Write rich text (bold, italic, underline)
• Use headings (H1–H6)
• Switch font family
• Use bulleted / numbered lists
• Set alignment (left/center/right/justify)
• Toggle theme (default dark, click to switch light)

How it works (simple)

This project is intentionally minimal:

• It is just static files (index.html, styles.css, app.js).
• It runs entirely in your browser (no backend server).
• It is hosted via GitHub Pages.

Rich text editor

Rich text editing is handled by QuillJS:

• Quill renders the editor UI and formatting.
• Quill is loaded from a CDN (no build step needed).

Saving your text

Your text is automatically saved to your browser using Local Storage:

• The app stores Quill “Delta” content as JSON.
• Refreshing the page restores what you last wrote.

Nothing is uploaded anywhere by this app.

Theme toggle

The theme toggle:

• Defaults to dark
• Persists your preference in Local Storage
• Uses CSS variables to style both the page and Quill’s toolbar/editor

Run locally

Because it’s static, you can run it in multiple ways:

Option A: open the file

• Open index.html directly in a browser.

Option B: run a small local server (recommended)

Python:

py -m http.server 8000

Then open:

• http://localhost:8000/

Project structure

• index.html – page layout + Quill toolbar
• styles.css – styling (including light/dark theme)
• app.js – Quill init, autosave/restore, toolbar visibility, theme toggle
