FrameBlocks gives content creators and developers a set of Gutenberg blocks that wrap content inside realistic UI mockups — without leaving the WordPress editor.
Included blocks:
<ul>
<li>Browser Frame — Safari or Chrome browser shell wrapping any inner content</li>
<li>Code Editor Frame — VS Code editor shell with sidebar, code zone, and terminal</li>
<li>Code Syntax Highlighter — Syntax-highlighted code powered by Shiki (50+ languages)</li>
<li>Device Frame — Phone, tablet, or laptop device shell</li>
<li>File Tree — VS Code-style file/folder tree</li>
<li>File Tree Item — Individual file or folder row inside a file tree</li>
<li>Social Post — Instagram or Facebook post mockup</li>
<li>Social Comment — Comment row nested inside a social post</li>
</ul>
All blocks are fully responsive using CSS container queries (<code>cqw</code> units), so they scale automatically with the column width — no manual resizing needed.

Some WordPress themes style images frames and drop-shadows. The Image Shadow plugin lets you have such image styling without having to use a special theme. It automatically adds a soft, realistic drop-shadow to the jpeg images in your post content. You can choose the shadow’s depth and orientation. You can even add frame to the image. You can let the image grow a shadow or you can ensure that the shadowed image fits in the same space as the original.
Version 1.1 lets you add shadows to only those images with a given class attribute (the attribute must come after the src attribute). You can also have shadows with a transparent background by leaving the background colour blank.
The shadowed images are cached on your server for fast delivery which means that your PHP setup must allow the creation of new files. You must also have the GD library installed.
NB I am aware that the settings screen, though functional, has problems in Internet Explorer.
<h3>Version History</h3>
