An interactive one-page website that provides a compendium on neurotransmitters (dopamine, norepinephrine, serotonin, and melatonin) and their role in psychophysiology. The page analyzes symptoms of deficiency/excess, core functions, interactions, and systemic connections to disorders such as depression, ADHD, and PTSD. Developed as a responsive, accessible tool for educational purposes.

This website is an educational compendium that illuminates the central neurotransmitters of the brain. It integrates scientific sources with interactive elements such as a heatmap for transmitter effects, multilingual support (DE/EN), and customizable difficulty levels (simple/advanced). Topics include:
- Symptoms of deficiency, core functions, and hyperactivity for each transmitter.
- An interactive heatmap to visualize effects on systems like mood, drive, sleep, etc.
- Systemic analyses of disorders (e.g., HPA axis in depression, phase delay in ADHD).
- Citation references with tooltips for sources (based on peer-reviewed studies).
The page is designed as a "one-pager" – everything in one HTML file, ideal for GitHub Pages or quick deployment.
- Multilingual & Multi-Level: Switch between German/English and simple/advanced language levels for broad accessibility.
- Interactive Heatmap: Visualizes transmitter effects with D3.js; colors and values adapt to the theme.
- Accordion Elements: Expandable sections for detailed analyses of disorders.
- Citation Tooltips: Hover effects for source links that are evidence-based (e.g., from PubMed, Nature, PMC).
- Responsive Design: Mobile-friendly with Tailwind CSS; grid layout for cards and heatmap.
- No Dependencies Beyond CDNs: No build tools needed – runs directly in the browser.
- None – the page is static and runs in any modern browser.
- For local development: A web browser (e.g., Chrome, Firefox).
- Clone the repository:
git clone https://github.com/fabianzimber/hormone-compendium.git
- Open
index.htmlin your browser. - (Optional) Deploy to GitHub Pages:

No further dependencies – all libraries (Tailwind, D3.js, Inter Font) are loaded via CDN.
- Switch Language: Click on DE/EN in the header.
- Difficulty Level: Choose "Advanced" or "Simple".
- Explore Heatmap: The matrix shows effect strengths (-2 to +2); hover for details (CSS-based).
- Check Sources: Hover over cited terms for tooltips with links.
Example: Switch to "Dark Theme" for better readability in low light.
- HTML5 & CSS3: Structure and styling with CSS variables for theming.
- Tailwind CSS: Utility-first CSS for responsive design (via CDN).
- D3.js: For dynamic heatmap generation (via CDN).
- JavaScript: Event listeners for switches (language, level, theme) and local storage (localStorage for theme).
- Fonts: Inter via CDN for modern typography.
- Accessibility: ARIA attributes implicit (expandable), High-Contrast mode.
