Plugin: mdl-shortcodes (Used by 14 domains)

Modern Design Library is a toolkit of opinionated Gutenberg blocks for WordPress. All optional blocks are registered using PHP-only block registration (autoRegister) — no JavaScript build step or Node.js tooling required.

The plugin ships with:

• Colored Line — a fully customisable horizontal separator block with striped, shade, and dotted style variants (classic JS-registered block).
• Advanced Separator (experimental) — a PHP-only separator with configurable width, height, padding, alignment, and three decorative variants.
• Advanced Heading (experimental) — 13 decorative heading styles, heading level selector (H1–H6), optional tagline, and full typography/spacing/border block support controls. Accent decorations automatically follow the text colour.
• Marquee (experimental) — a single infinitely scrolling text row. Stack multiple blocks for multi-row layouts. Speed (Slow/Medium/Fast) and direction (Left/Right) are configurable. Animation script is loaded lazily — only on pages containing the block.
• Call to Action (experimental) — a CTA banner with heading, subheading, button label/URL, three visual variants (Primary/Secondary/Dark), and native colour overrides.
• Author Box (experimental) — displays a user card with avatar, bio, email, and LinkedIn link. User is selected from a dropdown. LinkedIn URL is stored as user meta (set on the user’s profile page).

Optional blocks are enabled from Settings → Modern Design Library → Modules.

The optional blocks require the Gutenberg plugin or WordPress 7.0+ for the autoRegister block support.
