ACSS3 to ACSS4

ACSS3 to ACSS4 ACSS3 to ACSS4 is a WordPress admin utility plugin that helps migrate Automatic.css v2/v3 data to ACSS4 format on Bricks Builder sites. It focuses on the migration tasks that are awkward to do by hand: - running the ACSS4 settings migration chain - converting legacy ACSS CSS tokens inside Bricks element data - updating ACSS-related Bricks global classes - flagging CSS that still needs manual review Requirements - WordPress 6.0+ - PHP 8.0+ - ACSS4 installed and active - Bricks Builder installed and active for Bricks content migration What It Does The plugin adds a screen under Tools - ACSS3 to ACSS4 and runs the migration in three steps: 1. ACSS settings 2. Bricks element CSS 3. Bricks global classes During CSS conversion it rewrites common ACSS3 token patterns to their ACSS4 equivalents and annotates unsupported standalone channel variables for manual cleanup. Safety Notes - Create a full database backup before running the migration. - The plugin updates WordPress options and post meta in place. - Some CSS patterns cannot be migrated safely without context and are deliberately flagged instead of rewritten blindly.
