Additional Code Examples

Rust Example (Zola is written in Rust!)

use std::collections::HashMap;

fn main() {
    // Create a new HashMap to store user scores
    let mut scores = HashMap::new();
    
    // Insert some values
    scores.insert(String::from("Blue"), 10);
    scores.insert(String::from("Yellow"), 50);
    scores.insert(String::from("Red"), 25);
    
    // Access a value
    let team_name = String::from("Blue");
    let score = scores.get(&team_name).unwrap_or(&0);
    
    println!("Team {} score: {}", team_name, score);
    
    // Iterate over all key-value pairs
    for (key, value) in &scores {
        println!("{}: {}", key, value);
    }
}

Layout Features

The theme uses a three-column layout:

1. Left Sidebar: Navigation, search, and status panels
2. Main Content: Articles and primary content
3. Right Sidebar: Additional links, visitor counter, and GIF panels

The layout automatically collapses on mobile devices for better readability.

Retro Panels

The theme includes various retro-style panels:

1. Status Panel: Displays an animated GIF showing the current status
2. Links Panel: List of useful web links with matching emojis
3. Obligatory GIFs Panel: Display of animated GIFs in retro style
4. Visitor Counter: Simulated visitor counter that grows over time

Improved Accessibility

The theme has been equipped with numerous accessibility improvements:

• Skip Links: Allow skipping the navigation to get directly to the main content.
• Focus Indicators: Clearly visible focus styles for all interactive elements.
• Screen Reader Support: Use of ARIA attributes and semantic HTML.
• High Contrast: High-contrast color scheme for better readability.

Customization Options

The theme offers extensive customization options:

• Central configuration in sass/partials/_variables.scss
• Customizable header with background image
• Adjustable logo sizes for desktop and mobile
• Configurable GIF panels in different areas of the page
• Button styling and appearance settings

Form Elements

The theme includes retro-styled form elements:

Tables

The Retro-Compatible Zola Theme offers three different table shortcodes, each optimized for different use cases.

Table with Custom Column Widths

The table shortcode allows you to set the width of each column individually. The column widths are specified as percentages and must add up to 100%.

Syntax:

{​% table(cols="30%,70%") %​}
| Property | Description |
|----------|-------------|
| Name     | The name of the property |
| Value    | A longer description that needs more space |
{​% end %​}

Example:

Example with 4 Columns of Different Sizes

You can define any number of columns with different widths:

{​% table(cols="15%,25%,20%,40%") %​}
| ID | Category | Priority | Description |
|----|----------|----------|-------------|
| 001 | Hardware | High | New graphics card for workstation |
| 002 | Software | Medium | Operating system update |
| 003 | Network  | Low      | Office Wi-Fi optimization |
{​% end %​}

The result looks like this:

Shortcut Table

The shortcut_table shortcode is specifically optimized for displaying keyboard shortcuts. It uses fixed column widths (40% for the first column, 60% for the second) to ensure a consistent presentation.

Syntax:

{​% shortcut_table() %​}
| Action | Shortcut |
|--------|----------|
| Copy | Ctrl+C |
| Paste | Ctrl+V |
{​% end %​}

Example:

Changelog Table

The changelog_table shortcode is optimized for changelogs. It gives the date column a fixed width (100px) so that dates are displayed uniformly.

Syntax:

{​% changelog_table() %​}
| Date | Changes |
|------|--------|
| 2025-01-01 | Initial release |
| 2025-01-15 | Bug fixes |
{​% end %​}

Example: The changelog table at the beginning of this page uses the changelog_table shortcode.

Note on Displaying Shortcode Examples

To display shortcode examples in the documentation without them being executed, a special trick is used: invisible spaces (Zero-Width Spaces \u200b) are inserted between the curly braces and the percent signs. This prevents Zola from recognizing and executing the shortcodes, but they are not visible to the user.

Example: {\u200b% shortcode %\u200b} instead of {% shortcode %} (with an invisible space between { and % and between % and })

Markdown Troubleshooting

Common Layout Issues

When working with this theme (or any Markdown-based system), certain formatting issues can break your layout. Here are some common problems and solutions:

HTML-Like Syntax in Markdown

Problem Example:

Select **<Yes>** to enable automatic updates.

In this example, <Yes> might be interpreted as an HTML tag named “Yes”, causing layout issues.

Solutions:

1. Use quotes instead of angle brackets:

   Select **"Yes"** to enable automatic updates.
   

2. Use backticks to format as code:

   Select **`<Yes>`** to enable automatic updates.
   

3. Use HTML entities:

   Select **<Yes>** to enable automatic updates.
   

4. Use escape characters:

   Select **\<Yes\>** to enable automatic updates.
   

Other Common Markdown Issues

• Unclosed code blocks: Always ensure your code blocks have opening and closing backticks on their own lines.
• Malformed tables: Tables require a specific format with headers and separators.
• Nested HTML: Be careful when nesting HTML elements inside Markdown content.
