General Questions

No. Re-importing the same classes will cause errors. Each class can only be imported once. If you need to update a class:
  1. Delete it from Elementor’s Global Classes panel
  2. Re-import the updated CSS
Skelementor does not patch Elementor core files. Deactivating the plugin does not remove imported Elementor classes or variables automatically; those remain in Elementor until you delete them.
Works with both Elementor Free and Pro, as long as you have v4+ with the Atomic Editor enabled (on by default for new Elementor installs).

​
Import Questions

Elementor supports up to 1000 global classes natively. The built-in Skelementor Preset imports 976 classes for Elementor’s default desktop, tablet, and mobile breakpoints, so it stays inside that limit.
The shipped plugin workflow starts with the built-in preset. If you are debugging a reduced custom sample, smaller batches can still help isolate failures faster.
Try these solutions:
  • Import in smaller batches
  • Check for CSS syntax errors (missing units, semicolons)
  • Ensure you’re not re-importing existing classes
  • See our troubleshooting guide

​
Performance Questions

No. Global classes are native Elementor features. Skelementor only helps import them, and it doesn’t add frontend overhead.
No. Skelementor uses Elementor’s built-in Global Classes system, so there’s no performance impact.

​
Compatibility Questions

Elementor v4. The Atomic Editor (Atomic Elements, Classes, Variables) is stable in 4.x and ships with the normal Elementor plugin. New Elementor installations enable Atomic features by default. If you upgraded from an older setup or turned Atomic off, enable Atomic Editor under Elementor → Editor → Settings in WordPress admin.
WordPress 6.9 or higher is required. 6.9+
PHP 7.4 or higher is required. PHP 8.0+ is recommended for better performance. 7.4+

​

Yes! You can combine multiple classes for complex designs, such as pairing flex layout, spacing, borders, and button presets on the same Elementor block.

​
Customization Questions

Yes. To modify an existing class:
  1. Delete it from Elementor’s Global Classes panel
  2. Create your modified version
  3. Re-import through Skelementor
Use the bundled skelementor-utilities.css file as the reference artifact for the shipped framework. The stable built-in import path in the plugin is the Skelementor Preset.
Most common CSS properties are supported including:
  • Typography (font-size, font-weight, etc.)
  • Spacing (margin, padding, gap)
  • Layout (display, flexbox, positioning)
  • Colors (color, background-color, border-color)
  • Borders (width, style, radius)
  • Sizing (width, height, max-width)

​
Troubleshooting Questions

Check these:
  • Ensure Elementor v4 with Atomic Editor enabled
  • Verify classes were imported successfully
  • Clear Elementor cache: Elementor → Tools → Regenerate CSS
  • Check that you’re using atomic elements
Try these solutions:
  • Import in smaller batches (20-30 classes)
  • Check CSS syntax for errors
  • Ensure you’re not re-importing existing classes
  • Use the nuclear reset method (delete all classes, re-import)
That can be completely normal. On Elementor 4.1, global classes are stored as e_global_class posts, while the kit tracks labels, order, and class-to-post mappings in:
  • _elementor_global_classes_labels
  • _elementor_global_classes_labels_preview
  • _elementor_global_classes_order
  • _elementor_global_classes_order_preview
  • _elementor_global_classes_post_ids
Skelementor uses internal IDs with the sk-class-* prefix, while the visible label in Elementor stays clean, such as text-2xs.
