Jamie's Visual HTML Editor

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.
