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.

Why do you need it? It makes things so much easier when you have a lot of content to put on one page and tabs would be ideal. cTabs lets you add a tabbed content area directly in your post or page, without having to edit the theme template.
cTabs comes with a nice default style but you can edit it anyway you would like through the built in CSS editor in options menu. If you change the css and want to go back to the default, just reset the css in the options menu.

Content Tabs (cTabs) allows you to post content into separate tabs on a page using shortcodes. [shortcodes]
