Understanding Modern WordPress Footer Customization

Before diving into code, let’s understand what makes modern WordPress footer customization different from traditional approaches.

The Evolution of WordPress Footers

Traditional Approach (Before FSE):

  • Required editing footer.php template files
  • Custom HTML and PHP code for layouts
  • Widget areas registered in functions.php
  • Limited visual customization
  • Developer-dependent changes

Modern FSE Approach (2026):

  • Visual editing in Site Editor
  • 100% core WordPress blocks
  • No custom HTML needed
  • Live preview of changes
  • User-friendly customization
  • Future-proof implementation

Why FSE-First WordPress Footer Customization?

The WordPress footer customization approach in this guide prioritizes Full Site Editing features:

Benefits:

  1. Less Custom Code: Use core blocks instead of writing HTML
  2. Visual Editing: Users customize without coding
  3. Better Performance: WordPress-optimized blocks
  4. Future-Proof: Core features won’t break
  5. Easier Maintenance: WordPress handles updates
  6. Wider Compatibility: Works with any FSE theme

When to Use Custom Code:

  • Dynamic copyright year replacement
  • Back-to-top button functionality
  • Performance optimizations
  • Advanced features not available in core blocks

Part 1: Setting Up Footer Helper Functions

The first step in our WordPress footer customization implementation is creating helper functions for dynamic features.

Creating inc/footer-functions.php

This file handles dynamic copyright text, shortcodes, and the back-to-top button:

<?php
/**
 * Footer Helper Functions
 * WordPress Footer Customization - Episode 23
 *
 * @package Versana
 * @since 1.0.0
 */

if ( ! defined( 'ABSPATH' ) ) {
    exit;
}

/**
 * Get copyright text with dynamic year replacement
 *
 * Essential for WordPress footer customization
 *
 * @return string Copyright text with current year
 */
function versana_get_copyright_text() {
    // Get copyright text from theme options
    $copyright = versana_get_option( 
        'footer_copyright', 
        '&copy; {year} ' . get_bloginfo( 'name' ) . '. All rights reserved.' 
    );
    
    // Replace {year} placeholder with current year
    $copyright = str_replace( '{year}', date( 'Y' ), $copyright );
    
    // Also support %year% for backwards compatibility
    $copyright = str_replace( '%year%', date( 'Y' ), $copyright );
    
    return $copyright;
}

How This Works:

  1. Retrieves copyright text from theme options (user-configurable)
  2. Replaces {year} placeholder with current year (2026)
  3. Updates automatically every January 1st
  4. Provides fallback to site name if not configured

Adding Useful Shortcodes

Shortcodes make WordPress footer customization user-friendly:

/**
 * Copyright shortcode
 * Usage: [copyright]
 *
 * Displays full copyright text from theme options
 */
function versana_copyright_shortcode() {
    return versana_get_copyright_text();
}
add_shortcode( 'copyright', 'versana_copyright_shortcode' );

/**
 * Year shortcode
 * Usage: [year]
 *
 * Displays current year (e.g., 2026)
 */
function versana_year_shortcode() {
    return date( 'Y' );
}
add_shortcode( 'year', 'versana_year_shortcode' );

/**
 * Site name shortcode
 * Usage: [site_name]
 *
 * Displays website name
 */
function versana_site_name_shortcode() {
    return get_bloginfo( 'name' );
}
add_shortcode( 'site_name', 'versana_site_name_shortcode' );

Shortcode Usage Examples:

<!-- In a Paragraph block -->
&copy; [year] [site_name]. All rights reserved.

<!-- Or use the combined shortcode -->
[copyright]
<!-- Both produce: © 2026 Your Site Name. All rights reserved. -->

Back-to-Top Button Function

A key feature in WordPress footer customization is the back-to-top button:

/**
 * Render back to top button
 * Only renders if enabled in theme options
 */
function versana_render_back_to_top() {
    // Check if feature is enabled
    if ( ! versana_get_option( 'enable_back_to_top' ) ) {
        return;
    }
    ?>
    <button class="back-to-top" aria-label="<?php esc_attr_e( 'Back to top', 'versana' ); ?>">
        <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 24 24" fill="currentColor" aria-hidden="true">
            <path d="M12 4l-8 8h5v8h6v-8h5z"/>
        </svg>
    </button>
    <?php
}

/**
 * Add back to top button to footer
 * Hooked to wp_footer action
 */
function versana_add_back_to_top() {
    versana_render_back_to_top();
}
add_action( 'wp_footer', 'versana_add_back_to_top', 999 );

Key Features:

  • Conditional Rendering: Only shows if enabled in theme options
  • Accessibility: Proper ARIA labels for screen readers
  • Automatic Placement: Added via wp_footer hook (no template editing needed)
  • SVG Icon: Lightweight, scalable arrow icon

Part 2: Footer CSS for WordPress Footer Customization

Professional styling is crucial for effective WordPress footer customization.

Creating assets/css/footer.css

/**
 * Footer Styles
 * WordPress Footer Customization - Production Ready
 *
 * @package Versana
 * @since 1.0.0
 */

/* ==========================================================================
   Base Footer Styles
   ========================================================================== */

.site-footer {
    position: relative;
    margin-top: auto; /* Push to bottom for sticky footer effect */
}

/* Footer widgets/content area */
.footer-widgets {
    padding-top: var(--wp--preset--spacing--60, 2.5rem);
    padding-bottom: var(--wp--preset--spacing--60, 2.5rem);
}

/* Footer bottom/copyright area */
.footer-bottom {
    padding-top: var(--wp--preset--spacing--40, 1.5rem);
    padding-bottom: var(--wp--preset--spacing--40, 1.5rem);
    border-top: 1px solid var(--wp--preset--color--contrast, rgba(0, 0, 0, 0.1));
}

Back-to-Top Button Styling

A well-designed back-to-top button enhances WordPress footer customization:

/* ==========================================================================
   Back to Top Button
   ========================================================================== */

.back-to-top {
    position: fixed;
    bottom: 2rem;
    right: 2rem;
    width: 50px;
    height: 50px;
    background: var(--wp--preset--color--primary, #000);
    color: var(--wp--preset--color--base, #fff);
    border: none;
    border-radius: 50%;
    cursor: pointer;
    opacity: 0;
    visibility: hidden;
    transition: opacity 0.3s ease, visibility 0.3s ease, transform 0.3s ease;
    z-index: 998;
    display: flex;
    align-items: center;
    justify-content: center;
    box-shadow: 0 4px 12px rgba(0, 0, 0, 0.15);
}

.back-to-top:hover {
    transform: translateY(-3px);
    box-shadow: 0 6px 16px rgba(0, 0, 0, 0.2);
}

.back-to-top.show {
    opacity: 1;
    visibility: visible;
}

CSS Techniques Explained:

  1. Fixed Positioning: Button stays in corner while scrolling
  2. Hidden by Default: opacity: 0 and visibility: hidden
  3. Smooth Transitions: 0.3s ease for professional feel
  4. Hover Effect: Subtle lift (translateY(-3px)) on hover
  5. Circular Shape: border-radius: 50%
  6. Flexbox Centering: Centers SVG icon perfectly

Mobile Responsive Adjustments

Mobile optimization is essential for WordPress footer customization:

/* Mobile: Smaller button, adjusted position */
@media (max-width: 781px) {
    .back-to-top {
        width: 44px;
        height: 44px;
        bottom: 1.5rem;
        right: 1.5rem;
    }
    
    .back-to-top svg {
        width: 20px;
        height: 20px;
    }
}

Mobile Best Practices:

  • Minimum 44x44px touch target (Apple/Google guidelines)
  • Adequate spacing from screen edges
  • Scaled-down SVG for smaller buttons
  • No interference with content

Part 3: Back-to-Top JavaScript

JavaScript adds interactivity to WordPress footer customization.

Creating assets/js/footer.js

/**
 * Footer JavaScript
 * Back to Top Button Functionality
 *
 * @package Versana
 * @since 1.0.0
 */

(function() {
    'use strict';
    
    /**
     * Initialize back to top button
     */
    function initBackToTop() {
        const backToTopButton = document.querySelector('.back-to-top');
        
        if (!backToTopButton) {
            return;
        }
        
        const scrollThreshold = 300; // Show after scrolling 300px
        
        /**
         * Handle scroll events
         */
        function handleScroll() {
            const scrollPosition = window.pageYOffset || document.documentElement.scrollTop;
            
            if (scrollPosition > scrollThreshold) {
                backToTopButton.classList.add('show');
            } else {
                backToTopButton.classList.remove('show');
            }
        }
        
        /**
         * Scroll to top smoothly
         */
        function scrollToTop(e) {
            e.preventDefault();
            
            window.scrollTo({
                top: 0,
                behavior: 'smooth'
            });
            
            // Return focus to top for accessibility
            setTimeout(function() {
                const skipLink = document.querySelector('.skip-link');
                if (skipLink) {
                    skipLink.focus();
                }
            }, 500);
        }
        
        // Debounced scroll handler for performance
        let scrollTimeout;
        window.addEventListener('scroll', function() {
            if (scrollTimeout) {
                window.cancelAnimationFrame(scrollTimeout);
            }
            scrollTimeout = window.requestAnimationFrame(handleScroll);
        }, { passive: true });
        
        // Button click handler
        backToTopButton.addEventListener('click', scrollToTop);
        
        // Keyboard accessibility
        backToTopButton.addEventListener('keydown', function(e) {
            if (e.key === 'Enter' || e.key === ' ') {
                scrollToTop(e);
            }
        });
        
        // Initial check
        handleScroll();
    }
    
    /**
     * Initialize when DOM is ready
     */
    if (document.readyState === 'loading') {
        document.addEventListener('DOMContentLoaded', initBackToTop);
    } else {
        initBackToTop();
    }
    
})();

JavaScript Performance Optimizations

Modern WordPress footer customization requires optimized JavaScript:

1. RequestAnimationFrame for Scroll:

window.requestAnimationFrame(handleScroll);
  • Syncs with browser repaint cycle
  • Better than setTimeout or setInterval
  • Automatically pauses when tab is inactive

2. Passive Event Listeners:

{ passive: true }
  • Tells browser we won’t call preventDefault()
  • Improves scrolling performance
  • Especially important on mobile

3. Early Return Pattern:

if (!backToTopButton) {
    return;
}
  • Exits early if button doesn’t exist
  • Saves processing power
  • Prevents errors

4. Keyboard Accessibility:

if (e.key === 'Enter' || e.key === ' ') {
    scrollToTop(e);
}
  • Enter or Space activates button
  • Essential for keyboard users
  • WCAG 2.1 requirement

Part 4: Conditional Asset Loading

Performance optimization is crucial for WordPress footer customization.

Updating inc/enqueue.php

/**
 * Enqueue footer assets
 * Part of WordPress footer customization system
 */
function versana_enqueue_dynamic_assets() {
    
    // ... existing header assets ...
    
    // Footer CSS - Always load for consistent styling
    wp_enqueue_style(
        'versana-footer',
        get_template_directory_uri() . '/assets/css/footer.css',
        array(),
        wp_get_theme()->get( 'Version' )
    );
    
    // Footer JavaScript - Only if back-to-top is enabled
    if ( versana_get_option( 'enable_back_to_top' ) ) {
        wp_enqueue_script(
            'versana-footer',
            get_template_directory_uri() . '/assets/js/footer.js',
            array(),
            wp_get_theme()->get( 'Version' ),
            true // Load in footer
        );
    }
}
add_action( 'wp_enqueue_scripts', 'versana_enqueue_dynamic_assets' );

Why Conditional Loading Matters

Performance Benefits:

ScenarioCSS LoadedJS LoadedSavings
Back-to-top disabled✓✗~2KB
Back-to-top enabled✓✓0KB

Best Practices:

  1. Always load CSS – Needed for base footer styling
  2. Conditionally load JS – Only when feature is enabled
  3. Use theme version – For cache busting
  4. Load scripts in footer – Better page load performance

Part 5: Creating Footer Templates with Core Blocks

The heart of FSE-based WordPress footer customization is using core WordPress blocks.

Understanding WordPress Core Blocks for Footers

Available Blocks for Footer Creation:

  1. Group Block – Container/wrapper
  2. Columns Block – Multi-column layouts
  3. Navigation Block – Footer menus
  4. Social Links Block – Social icons
  5. Paragraph Block – Text content
  6. Heading Block – Section titles
  7. Site Logo Block – Branding
  8. Site Title Block – Site name
  9. Spacer Block – Vertical spacing

All standard WordPress blocks – no custom blocks required!

Template 1: 3-Column Footer (Recommended)

This is the most versatile template for WordPress footer customization:

<!-- wp:group {"align":"full","className":"site-footer","backgroundColor":"contrast","textColor":"base"} -->
<div class="wp-block-group alignfull site-footer has-base-color has-contrast-background-color">
    
    <!-- Footer Widgets Area (3 Columns) -->
    <!-- wp:group {"align":"wide","className":"footer-widgets"} -->
    <div class="wp-block-group alignwide footer-widgets">
        
        <!-- wp:columns {"align":"wide"} -->
        <div class="wp-block-columns alignwide">
            
            <!-- Column 1: About -->
            <!-- wp:column -->
            <div class="wp-block-column">
                <!-- wp:heading {"level":3,"fontSize":"medium"} -->
                <h3 class="has-medium-font-size">About</h3>
                <!-- /wp:heading -->
                
                <!-- wp:paragraph {"fontSize":"small"} -->
                <p class="has-small-font-size">A brief description of your website or company.</p>
                <!-- /wp:paragraph -->
                
                <!-- wp:social-links {"className":"is-style-logos-only"} -->
                <ul class="wp-block-social-links is-style-logos-only">
                    <!-- wp:social-link {"url":"#","service":"facebook"} /-->
                    <!-- wp:social-link {"url":"#","service":"twitter"} /-->
                    <!-- wp:social-link {"url":"#","service":"instagram"} /-->

                <!-- wp:heading {"level":3,"fontSize":"medium"} -->
                <h3 class="has-medium-font-size">Quick Links</h3>
                <!-- /wp:heading -->
                
                <!-- wp:navigation {"overlayMenu":"never","layout":{"type":"flex","orientation":"vertical"}} /-->
            </div>

Part 7: Mobile Responsive WordPress Footer Customization

Mobile optimization is critical for modern WordPress footer customization.

How WordPress Handles Mobile Responsiveness

Automatic Features (No Custom CSS Needed):

  1. Columns Block Auto-Stacking:
    • Desktop (> 782px): Side by side
    • Mobile (< 782px): Stacked vertically
    • Handled by WordPress core
  2. Navigation Block:
    • Adjusts automatically
    • Vertical layout on mobile
    • Touch-friendly tap targets
  3. Social Links Block:
    • Maintains proper sizing
    • Adequate spacing on mobile
    • Touch-optimized

Custom Mobile Enhancements

For optimal WordPress footer customization, add these mobile styles:

@media (max-width: 781px) {
    /* Footer navigation - ensure vertical stacking */
    .site-footer .wp-block-navigation__container {
        flex-direction: column;
        align-items: flex-start;
    }
    
    /* Footer widgets - tighter spacing on mobile */
    .footer-widgets {
        padding-top: var(--wp--preset--spacing--50, 2rem);
        padding-bottom: var(--wp--preset--spacing--50, 2rem);
    }
    
    /* Copyright text - ensure readability */
    .footer-copyright {
        font-size: 0.8125rem;
        line-height: 1.6;
    }
}

Mobile Testing Checklist

Essential for WordPress footer customization:

  • [ ] Columns stack vertically
  • [ ] All text is readable
  • [ ] Links have 44px+ touch targets
  • [ ] Social icons properly sized
  • [ ] No horizontal scrolling
  • [ ] Back-to-top button accessible
  • [ ] Adequate spacing between elements

Part 8: Accessibility in WordPress Footer Customization

WCAG 2.1 AA compliance is essential for professional WordPress footer customization.

Semantic HTML Structure

WordPress blocks provide semantic HTML automatically:

<footer class="site-footer" role="contentinfo">
    <nav aria-label="Footer Navigation">
        <!-- Navigation links -->
    </nav>
</footer>

Automatic Accessibility Features:

  • <footer> tag with role="contentinfo"
  • <nav> tag with aria-label
  • Proper heading hierarchy (H1 → H2 → H3)
  • Link purposes clearly defined

Keyboard Navigation

Ensure keyboard accessibility in WordPress footer customization:

// Back-to-top keyboard support
backToTopButton.addEventListener('keydown', function(e) {
    if (e.key === 'Enter' || e.key === ' ') {
        scrollToTop(e);
    }
});

Testing:

  1. Use Tab key to navigate footer
  2. All links should be focusable
  3. Focus indicators visible
  4. Logical tab order
  5. Enter/Space activates links

ARIA Labels

Add descriptive labels for assistive technologies:

<button class="back-to-top" aria-label="Back to top">
    <svg aria-hidden="true">...</svg>
</button>

Best Practices:

  • Use aria-label for icon-only buttons
  • Add aria-hidden="true" to decorative SVGs
  • Provide text alternatives for icons
  • Use semantic HTML elements

Color Contrast

Meet WCAG requirements in WordPress footer customization:

ElementMinimum RatioExample
Body text4.5:1#333 on #fff
Large text3:1#666 on #fff
UI components3:1Buttons, links

Part 9: Performance Optimization

Optimized performance sets apart professional WordPress footer customization.

File Size Optimization

Current File Sizes:

  • footer.css: ~3KB uncompressed, ~1KB gzipped
  • footer.js: ~2KB uncompressed, ~0.7KB gzipped
  • Total: ~5KB uncompressed, ~1.7KB gzipped

Optimization Techniques:

  1. Minification:
# Production builds should minify CSS/JS
csso footer.css --output footer.min.css
terser footer.js --compress --mangle --output footer.min.js
  1. Gzip Compression:
  • Enable on server (Apache/Nginx)
  • 60-70% size reduction
  • Automatic in modern hosting
  1. Critical CSS:
// Inline critical footer CSS
add_action( 'wp_head', function() {
    echo '<style>' . file_get_contents( get_template_directory() . '/assets/css/footer-critical.css' ) . '</style>';
});

Conditional Loading Implementation

// Load footer.js ONLY when back-to-top is enabled
if ( versana_get_option( 'enable_back_to_top' ) ) {
    wp_enqueue_script( 'versana-footer', ... );
}

Performance Savings:

ScenarioFiles LoadedSizeLoad Time
Basic footerfooter.css only~1KB~30ms
With back-to-topfooter.css + footer.js~1.7KB~50ms

Browser Caching

// Use theme version for cache busting
wp_enqueue_style(
    'versana-footer',
    get_template_directory_uri() . '/assets/css/footer.css',
    array(),
    wp_get_theme()->get( 'Version' ) // Updates cache on version change
);

Cache Strategy:

  1. Version changes = cache bust
  2. Long cache duration (1 year)
  3. Automatic browser update
  4. No manual cache clearing

Part 10: Advanced WordPress Footer Customization Techniques

Take your WordPress footer customization to the next level.

Adding Newsletter Signup

Integrate email capture in footer:

<!-- Using Jetpack Subscribe block -->
<!-- wp:jetpack/subscriptions /-->

<!-- Or Contact Form 7 shortcode -->
<!-- wp:shortcode -->
[contact-form-7 id="123"]
<!-- /wp:shortcode --> 
<!-- Or custom HTML block --> 
<!-- wp:html --> 
<form action="https://yourlist.com/subscribe" method="post"> 
<input type="email" name="email" placeholder="Your email" required> 
<button type="submit">Subscribe</button> 
</form> 
<!-- /wp:html -->

Multi-Language Footer Support

For international WordPress footer customization:

// WPML/Polylang compatible
function versana_get_copyright_text() {
    $copyright = versana_get_option( 'footer_copyright' );
    
    // Apply translation filters
    $copyright = apply_filters( 'wpml_translate_single_string', $copyright, 'versana', 'footer_copyright' );
    
    return str_replace( '{year}', date( 'Y' ), $copyright );
}

Footer Sticky to Bottom

Make footer stick to bottom on short pages:

/* Add to footer.css */
html, body {
    height: 100%;
}

body {
    display: flex;
    flex-direction: column;
}

.site-footer {
    margin-top: auto;
}

Dynamic Footer Content

// Show different footer based on page type
add_filter( 'template_include', function( $template ) {
    if ( is_front_page() ) {
        // Use home footer
        locate_template( 'parts/footer-home.html', true );
    } elseif ( is_singular( 'product' ) ) {
        // Use product footer
        locate_template( 'parts/footer-product.html', true );
    }
    return $template;
});

Part 11: Troubleshooting Common Issues

Solve common problems in WordPress footer customization.

Issue #1: Copyright Year Not Updating

Symptom: Shows {year} instead of 2026

Solutions:

  1. Check Shortcode:
<!-- Use [year] not {year} in blocks -->
&copy; [year] Your Site

<!-- Or use {year} in theme options only -->
Theme Options: &copy; {year} My Site
  1. Verify Function:
// Check footer-functions.php is loaded
if ( ! function_exists( 'versana_get_copyright_text' ) ) {
    die( 'Footer functions not loaded!' );
}
  1. Clear Caches:
  • Browser cache (Ctrl+Shift+R)
  • WordPress cache
  • CDN cache
  • Object cache

Issue #2: Back-to-Top Button Not Appearing

Symptom: Button doesn’t show when scrolling

Solutions:

  1. Verify Enabled:
// Check theme option
var_dump( versana_get_option( 'enable_back_to_top' ) );
// Should output: bool(true)
  1. Check JavaScript Loading:
  • Open DevTools → Network tab
  • Filter by “JS”
  • Verify footer.js is loaded
  1. Scroll Threshold:
// Ensure you've scrolled past threshold
const scrollThreshold = 300; // Must scroll 300px
  1. CSS Class:
// Button needs .show class
console.log( document.querySelector('.back-to-top').classList );

Issue #3: Columns Not Stacking on Mobile

Symptom: Columns remain side-by-side on mobile

Solutions:

  1. Use Core Columns Block:
  • Not custom HTML/CSS grid
  • WordPress Columns block auto-stacks at 782px
  1. Check Breakpoint:
/* Verify this CSS exists */
@media (max-width: 782px) {
    .wp-block-columns {
        flex-direction: column;
    }
}
  1. Test at Correct Width:
  • Open DevTools
  • Resize below 782px
  • Columns should stack

Issue #4: Social Icons Not Displaying

Symptom: Shows text instead of icons

Solutions:

  1. Use Social Links Block:
  • Not regular link blocks
  • Insert → Social Icons
  1. Select Logos Only Style:
  • Click Social Links block
  • Styles panel → “Logos Only”
  1. Verify Services:
  • Each link needs correct service
  • Facebook, Twitter, Instagram, etc.

Issue #5: Footer CSS Not Loading

Symptom: Unstyled footer

Solutions:

  1. Check Enqueue:
// Verify footer.css is enqueued
add_action( 'wp_print_styles', function() {
    global $wp_styles;
    var_dump( $wp_styles->registered['versana-footer'] );
});
  1. Verify File Path:
// Check file exists
$file = get_template_directory() . '/assets/css/footer.css';
var_dump( file_exists( $file ) );
  1. Clear Cache:
  • Hard refresh (Ctrl+Shift+R)
  • Disable cache plugins
  • Check .htaccess for caching rules

Frequently Asked Questions

Q1: Do I need to edit footer.php for WordPress footer customization?

A: No! With FSE (Full Site Editing), you edit footers visually in the Site Editor. No PHP file editing required. This is the modern approach to WordPress footer customization.

Q2: Will my footer work on all devices?

A: Yes. WordPress Columns block automatically stacks on mobile (< 782px). Our CSS ensures proper responsive behavior. All core blocks are mobile-optimized.

Q3: How do I add a different footer to specific pages?

A: Use template patterns or conditional logic:

// In template file
if ( is_front_page() ) {
    get_template_part( 'parts/footer', 'home' );
} else {
    get_template_part( 'parts/footer' );
}

Q4: Can I use this with page builders like Elementor?

A: This WordPress footer customization approach is designed for block themes. For page builders, you’d need to adapt the approach to their footer builder systems.

Q5: How do I change the back-to-top button color?

A: The button uses var(--wp--preset--color--primary). Change your primary color in theme.json:

{
  "settings": {
    "color": {
      "palette": [
        {
          "slug": "primary",
          "color": "#your-color"
        }
      ]
    }
  }
}

Q6: Does this work with multilingual sites?

A: Yes! WPML and Polylang compatible. The shortcodes work across languages, and you can create different footer templates per language.

Q7: How do I add a newsletter form to my footer?

A: Use any of these methods:

  • Jetpack Subscribe block
  • Contact Form 7 shortcode
  • Mailchimp embed code (HTML block)
  • Newsletter plugin block

Q8: Can I have different footers for different post types?

A: Yes! Create template variations:

  • parts/footer.html (default)
  • parts/footer-product.html (WooCommerce)
  • parts/footer-post.html (blog posts)

Then assign in template files or use conditional logic.
