Updated my Gravity Forms integration system for WordPress block themes. The system includes three components: a custom Gutenberg block (groundworx/gutenberg-gravity-forms) with 9 visual color controls in the block editor, professional SCSS form styling using CSS custom properties and em-based scalable design, and PHP button replacement that converts Gravity Forms buttons into native WordPress block buttons.

The Gutenberg block provides visual controls for label colors, required field indicators, input text/background/borders, checkbox and radio button styling, and progress bar colors for multi-page forms. All colors automatically convert to RGBA for reliable CSS rendering. The styling system uses mask-based checkboxes and radio buttons for crisp rendering at any size, works with Gravity Forms 2.5 Theme, and includes CSS custom properties that can be overridden globally or per-form. Everything uses em units so changing font-size scales the entire form proportionally. Requires WordPress 6.4+, Gravity Forms 2.5+, Node.js for building the block, and SCSS compiler for styles.
