Block Elements
warning
Block Elements can add lots of DOM and styles. Keep them lean and re-check CLS/INP after deploying block-heavy sections.
Block Elements Explained
| Element | What it is | Best for |
|---|---|---|
| Block Element | Block editor content rendered conditionally | Hero sections, CTAs, reusable page sections |
| Hook Element | Raw hook injection | Small HTML snippets or scripts |
| Display rules | Conditions for output | Targeting specific pages, post types, archives |
Why It Matters
- Block Elements let non-PHP workflows create reusable layout sections.
- Display rules prevent per-page copy/paste content drift.
- You can often replace template overrides with a Block Element.
How It Works
GP Premium stores block content and renders it when rules match. Under the hood, it still attaches to a hook or region, but authoring happens in the block editor.
Practical Walkthrough
Step 1: Verify Required Plugins
verify-block-plugins.sh
cd /var/www/html
wp plugin list | grep -E "gp-premium|generateblocks" || true
Step 2: Locate Relevant Plugin Folders
locate-plugin-folders.sh
cd /var/www/html
ls -lah wp-content/plugins/gp-premium | head -n 40
ls -lah wp-content/plugins/generateblocks 2>/dev/null | head -n 40 || true
Step 3: Inventory Existing Elements (Optional)
inventory-elements.sh
cd /var/www/html
wp post list --post_type=gp_elements --fields=ID,post_title,post_status --format=table 2>/dev/null || true
Step 4: Capture a Before/After Snapshot for Rollback
snapshot-elements-before-after.sh
cd /var/www/html
wp post list --post_type=gp_elements --fields=ID,post_title,post_status --format=csv 2>/dev/null > /tmp/gp-elements.before.csv || true
# After you create/edit a Block Element, run:
wp post list --post_type=gp_elements --fields=ID,post_title,post_status --format=csv 2>/dev/null > /tmp/gp-elements.after.csv || true
diff -u /tmp/gp-elements.before.csv /tmp/gp-elements.after.csv | head -n 80
Practical Examples
Example 1: Replace a Hard-Coded Hero with a Block Element
Goal: a hero that appears only on the homepage.
- Build the hero with blocks (prefer GenerateBlocks for layout control).
- Set display rules: Front page only.
- Keep images optimized (WebP, correct dimensions).
Example 2: Create a Reusable CTA Section
Create one CTA block section, then reuse it across:
- Product pages
- Blog posts
- Category archives
Display rules keep the output consistent.
Example 3: Debug Block Element Scope
If an element shows up unexpectedly, export the element list and check rule intent.
export-elements-list.sh
cd /var/www/html
wp post list --post_type=gp_elements --fields=ID,post_title,post_status --format=csv 2>/dev/null > /tmp/gp-elements.csv || true
head -n 20 /tmp/gp-elements.csv 2>/dev/null || true
Example 4: A Simple Performance Budget for Block Sections
| Budget item | Target | Why |
|---|---|---|
| Hero images | < 250KB (optimized) | Protects LCP |
| Nested blocks | Keep shallow | Deep nesting hurts editor UX and DOM size |
| Custom CSS | Prefer small component rules | Easier caching and maintenance |
Best Practices
| Practice | Why |
|---|---|
| Prefer GenerateBlocks for layout | Predictable output and fewer surprises |
| Keep block sections small | Improves INP and reduces CSS bloat |
| Use display rules like a firewall | Prevents accidental global output |
| Optimize images used in heroes | Large images often dominate LCP |
| Reuse patterns/components | Prevents drift across pages |
Troubleshooting
| Symptom | Cause | Fix |
|---|---|---|
| Element not visible | Rule mismatch or caching | Widen rules temporarily, purge LSCache |
| Styling missing | Block CSS not loaded | Verify plugin active and check minify plugins |
| Layout shifts | Images without dimensions | Set width/height and use responsive images |
| Editor looks different | Theme/editor styles differ | Validate on the logged-out front end and adjust CSS carefully |
Hands-On
- Create a Block Element that renders on one page only.
- Add an image and confirm it has correct dimensions to avoid CLS.
- Disable the element and confirm rollback is immediate.
- Create a second Block Element for a different page type (archive or post type) and confirm rules do not overlap.
Quick Reference
| Task | Command |
|---|---|
| List elements | wp post list --post_type=gp_elements --fields=ID,post_title,post_status |
| Verify GenerateBlocks | `wp plugin list |
