This page documents its own construction, highlighting design decisions, HTML structure, CSS usage, and usability considerations.

The project demonstrates typography, colors, layout, responsiveness, interactivity, and code styling in action.

The page aims to teach how to structure a technical documentation site functionally and visually.

Navigation is easy with a fixed sidebar, smooth scrolling, and clear section separation.

External references and examples provide context for best practices and implementation details.

We use Arial, Helvetica, sans-serif for readability across devices.

Headers are larger and spaced to guide the reader's eye through sections.

Font sizes use rem units for scalability and line-height for comfortable reading.

Code example:

body { 
    font-family: Arial, sans-serif; 
    font-size: 1rem; 
    line-height: 1.8; 
}
            

• Use readable font families.
• Maintain visual hierarchy with header sizes.
• Adjust line-height for legibility.

The navbar uses dark background (#1e1e1e) to contrast with the main content (#fafafa).

Links are light gray (#e0e0e0) with hover (#fff) and active (#555) states.

Code blocks use a neutral background (#f4f4f4) for clarity without harsh contrast.

Code example:

#navbar { 
    background-color: #1e1e1e; 
    color: #e0e0e0; 
}
            

• Maintain sufficient contrast for accessibility.
• Use consistent color palettes across sections.
• Avoid overly saturated colors for readability.

The navbar is fixed on the left (position: fixed) for persistent navigation.

Main content uses flexible width and padding for a spacious layout.

Sections are visually separated with padding, border-radius, and subtle shadows.

Code example:

.main-section { 
    padding: 2rem; 
    border-radius: 0.8rem; 
    box-shadow: 0 4px 15px rgba(0,0,0,0.05); 
}
            

• Use visual separation for clarity.
• Maintain responsive padding and margins.
• Keep layout consistent across devices.

Media queries adjust layout for smaller screens, stacking content vertically and making the navbar horizontal.

Relative units like %, vw, rem ensure content scales naturally.

Smooth scroll improves user experience when navigating sections.

Code example:

@media (max-width: 768px) { 
    #navbar {
        width: 6rem; 
        position: fixed; 
    }
}
            

• Test design on multiple devices.
• Ensure readability and usability on small screens.
• Use relative units instead of fixed pixels.

Links provide hover and click feedback via subtle scaling and shadow effects.

The “Back to Top” button allows fast navigation without JavaScript logic.

Code example:

#backToTop:hover {
    background-color: #333; 
    transform: translateY(-2px); 
}
            

• Keep interactive elements subtle and functional.
• Provide visual cues for user actions.
• Ensure interactivity works on touch and mouse devices.

Code snippets use monospace font, padding, and neutral backgrounds.

Separating code from regular text enhances readability.

Example:

code { 
    background-color: #f4f4f4; 
    padding: 0.6rem; 
    border-radius: 0.4rem;
}
            

• Maintain readable code blocks.
• Keep visual separation from normal text.
• Use consistent code styling.

Use box-sizing: border-box; for consistent sizing.

Keep HTML and CSS separate for maintainability.

Prefer flexible units and responsive design.

Ensure interactions are subtle and enhance usability.

Always test across devices for layout consistency and accessibility.
