Modern Design Library is a toolkit of opinionated Gutenberg blocks for WordPress. All optional blocks are registered using PHP-only block registration (<code>autoRegister</code>) — no JavaScript build step or Node.js tooling required.
The plugin ships with:
<ul>
<li>Colored Line — a fully customisable horizontal separator block with striped, shade, and dotted style variants (classic JS-registered block).</li>
<li>Advanced Separator (experimental) — a PHP-only separator with configurable width, height, padding, alignment, and three decorative variants.</li>
<li>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.</li>
<li>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.</li>
<li>Call to Action (experimental) — a CTA banner with heading, subheading, button label/URL, three visual variants (Primary/Secondary/Dark), and native colour overrides.</li>
<li>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).</li>
</ul>
Optional blocks are enabled from Settings → Modern Design Library → Modules.
The optional blocks require the Gutenberg plugin or WordPress 7.0+ for the <code>autoRegister</code> block support.
