vivify

Pros of WP Rig

• More actively maintained with regular updates and contributions
• Focused on WordPress theme development with built-in best practices
• Extensive documentation and community support

Cons of WP Rig

• Steeper learning curve for beginners
• Requires more setup and configuration compared to simpler themes

Code Comparison

Vivify (CSS):

.vivify.fadeIn {
  opacity: 0;
  animation-name: fadeIn;
}

@keyframes fadeIn {
  from { opacity: 0; }
  to { opacity: 1; }
}

WP Rig (PHP):

function wprig_content_width() {
    $GLOBALS['content_width'] = apply_filters( 'wprig_content_width', 720 );
}
add_action( 'after_setup_theme', 'wprig_content_width', 0 );

Summary

Vivify is a lightweight CSS animation library, while WP Rig is a more comprehensive WordPress theme development toolkit. Vivify offers simple, ready-to-use animations, making it easier for beginners to implement basic effects. WP Rig, on the other hand, provides a robust foundation for creating modern, performant WordPress themes, but requires more advanced knowledge of WordPress development.

Pros of Understrap

• More comprehensive WordPress theme framework with Bootstrap integration
• Actively maintained with regular updates and larger community support
• Extensive documentation and examples for easier customization

Cons of Understrap

• Steeper learning curve for beginners due to its complexity
• Potentially heavier and slower than minimalist themes like Vivify
• May require more setup and configuration for simple projects

Code Comparison

Understrap (functions.php):

function understrap_scripts() {
    wp_enqueue_style( 'understrap-styles', get_stylesheet_directory_uri() . '/css/theme.min.css', array(), $theme_version );
    wp_enqueue_script( 'jquery' );
    wp_enqueue_script( 'understrap-scripts', get_template_directory_uri() . '/js/theme.min.js', array(), $theme_version, true );
}
add_action( 'wp_enqueue_scripts', 'understrap_scripts' );

Vivify (style.css):

body {
    font-family: 'Open Sans', sans-serif;
    font-size: 14px;
    line-height: 1.42857143;
    color: #333;
    background-color: #fff;
}

While Understrap provides a more robust framework with Bootstrap integration and extensive customization options, Vivify offers a simpler, lightweight alternative for basic WordPress themes. The code comparison illustrates Understrap's more complex setup for scripts and styles, compared to Vivify's straightforward CSS approach.

Pros of Sage

• More actively maintained with frequent updates and contributions
• Extensive documentation and community support
• Built-in Webpack configuration for modern asset management

Cons of Sage

• Steeper learning curve for beginners
• Requires more setup and configuration
• Heavier footprint due to additional features

Code Comparison

Sage (theme setup):

add_action('after_setup_theme', function () {
    add_theme_support('title-tag');
    add_theme_support('post-thumbnails');
    add_theme_support('html5', ['caption', 'comment-form', 'comment-list', 'gallery', 'search-form']);
});

Vivify (theme setup):

function vivify_setup() {
    add_theme_support('automatic-feed-links');
    add_theme_support('title-tag');
    add_theme_support('post-thumbnails');
}
add_action('after_setup_theme', 'vivify_setup');

Both themes use similar WordPress functions for basic theme setup, but Sage's approach is more modern with an anonymous function and additional HTML5 support.
