Switching from code view to visual view causes layout loss or broken HTML.
Content Breaks When Switching Between Visual and Code Editor
Key Points: Editing in Code Editor and switching back to Visual view causes changes to disappear or HTML to break.
You hand-code a custom layout in the Code Editor — and then it all collapses after switching back to Visual. Your neatly nested tags now look like they went through a blender.
📉 What’s Going Wrong
- HTML sanitization in Visual mode strips or reshuffles tags
- Block editor tries to re-parse unregistered HTML as unknown blocks
- Conflicts with reusable blocks or theme filters
🛠️ What You Can Do
- Make final edits in Code Editor and avoid switching modes
- Save and preview changes before toggling back
- Use Custom HTML blocks to preserve structure inside Visual mode
💡 Note
Mixing block structure and raw HTML requires care — the editor isn’t a true IDE.
