NOTE: This block plugin is only compatible with hybrid and block themes.
The card block can be used as a content container with custom controls for padding, margin, background color/gradient and, hence the name of the block – box shadow.

Card Block with Box Shadow

Add a custom card block to WordPress block editor with box shadow setting.

OpenGraph Fallback Embed adds a custom Gutenberg block and an auto-embed fallback that renders rich link cards using OpenGraph metadata from any URL.
Features:
<ul>
<li>OpenGraph Embed block — Paste any URL to embed it as a styled card showing the page’s title, description, image, and site name.</li>
<li>Auto-embed fallback — When WordPress can’t find an oEmbed provider for a URL pasted on its own line, this plugin automatically fetches the page’s OpenGraph tags and renders a card instead of a plain link.</li>
<li>Graceful degradation — Falls back to Twitter Card meta tags, then to HTML <code><title></code> and <code><meta name="description"></code> when OpenGraph tags are missing.</li>
<li>Transient caching — Fetched metadata is cached for 7 days to minimise external requests.</li>
</ul>
