Description

Stackable adds 42 custom blocks to the WordPress editor, paired with a global design system that centralizes colors, typography, spacing, borders, buttons, and icons to apply across the entire site at once. The library includes hundreds of ready-made designs and dozens of full-page templates that inherit the block theme’s styling, serving anyone who needs to build pages in Gutenberg without reaching for an external builder.

Key Features of Stackable

  • 42 custom blocks
    A set of native editor blocks you enable as your project requires.
  • Global design system
    Central controls for color, typography, spacing, border, button, and icon that apply to the entire site.
  • Hundreds of ready-made designs
    A library of patterns and dozens of block layouts importable directly in the editor.
  • Full-page templates
    Dozens of complete pages ready to insert and adjust to your project’s content.
  • Block theme inheritance
    Designs read styles from theme.json and adopt the visual identity already defined.

Benefits of Stackable

  • Adjust in one place
    Changing a global color or font carries through every page without manual editing.
  • Less time per page
    Starting from a ready-made pattern cuts the repetitive work of building sections from scratch.
  • Consistent visuals maintained
    Global schemes prevent style drift between pages built by different people.
  • Lightweight loading
    The blocks run on top of the native editor, skipping the extra layer of a visual builder.

Who Is Stackable For?

  • Anyone who publishes content frequently and wants visual sections built right inside the block editor.
  • Anyone building client sites who needs to standardize colors, fonts, and spacing at scale.
  • Aimed at those already working with block themes who want to expand their layout repertoire without switching tools.

How to Download Stackable

Stackable is available for download here on Ultrapack. Step-by-step install instructions for this file are in the How to install tab, next to the description. Once activated, the blocks and global controls appear inside the WordPress block editor.

For anyone building in the native editor, Stackable occupies the space between plain Gutenberg and a visual builder: it expands the block repertoire and design library without leaving the standard WordPress workflow. The combination of global schemes with patterns that read theme.json favors long-term projects, where each new page needs to be born aligned with what already exists.
