Jamie's Visual HTML Editor

Description

Jamie’s Visual HTML Editor enhances the core Custom HTML block so you can paste in any HTML and let editors change the copy and images without touching the markup.

  • Edit content — render the HTML live and click any heading, paragraph, list item, link, or button to edit its text in place. Click any <img> to replace it from the Media Library, change its URL, or edit its alt text. Add data-vc-bg and an inline background-image on hero sections to make backgrounds editable too.
  • Edit code — the normal raw-HTML view for pasting or writing markup.
  • Wide and Full width — adds Wide and Full alignment options to the Custom HTML block. It does not change the block’s content width; it only lets you choose Wide or Full alignment so full-bleed sections can break out of the theme’s content area.

Content is stored as a native Custom HTML block, so revisions and saving work exactly as they do in core. The plugin only changes how the block is edited and aligned.

This plugin is open source. See the Development section below for the full human-readable source code and build instructions.

Development

This plugin is open source (GPL-2.0-or-later). The complete, human-readable source code — including the un-minified JavaScript in src/ and the build configuration — is publicly available at:

https://github.com/jamiemarsland/jamies-visual-html-editor

The compiled files in build/ are generated with @wordpress/scripts:

npm install
npm run build

No third-party libraries are bundled; the plugin relies only on the WordPress-provided editor packages (@wordpress/*).

  1. Upload the jamies-visual-html-editor folder to the /wp-content/plugins/ directory, or install the plugin through the Plugins screen in WordPress.
  2. Activate the plugin through the Plugins screen.
  3. Add or select a Custom HTML block in the block editor and use the “Edit content” / “Edit code” toolbar buttons. Use the alignment control for Wide or Full width.
  1. The block toolbar in "Edit content" mode — click any text or image to edit it in place.

Which blocks does this affect?

It enhances the core Custom HTML block (core/html). Other blocks are unchanged.

Will it change my saved HTML?

The block is still stored as a standard Custom HTML block. Editing text updates the words; editing an image updates its src and alt attributes. Structure, classes, and styles stay unchanged. Switch to “Edit code” to see the raw markup.

Can I replace images?

Yes. In “Edit content” mode, click an image to open a modal where you can choose a replacement from the Media Library, paste an external URL, or edit the alt text.

Can I replace hero background images?

Yes. In “Edit content” mode, hover a hero section whose background is set inline or in a <style> block inside the HTML, then click Edit background. You can also tag any element with data-vc-bg and an inline background-image. Gradients layered with a photo are supported — only the photo URL is swapped.

Why isn’t my section full width?

Set the block’s alignment to Full width using the block toolbar. The block must be a direct child of the content area for the theme’s layout to break it out.

Great Plugin

Great plugin, Jamie! Thought I'd give it a try on a new website I've been building which has a few custom HTML blocks. Works really well. 👍

Simply fantastic.

I had been dreaming of a plugin with this functionality for years, congratulations, my friend!

The plugin is a great advancement for WordPress. It helps us easily edit the AI-generated content blocks on the go!

  • Added a plugin icon.

0.2

  • Clarified in the description that the plugin adds Wide and Full alignment options and does not change the block’s content width.

0.1

  • Initial release.
  • Custom HTML block: click-to-edit text, plus image, link, and background editing with an “Edit content” / “Edit code” toggle.
