WordPress 7.0 is officially standardizing the editing experience. The goal? To make the "Post Editor" act exactly like the "Site Editor" by running it inside an iframe.

What’s changing?
Up until now, the post editor lived in the same "space" as the WordPress admin. This caused constant CSS collisions where admin styles leaked into your content. In 7.0, your content is finally isolated in its own "sandbox" (iframe).

🤔 Why this matters?

True WYSIWYG: Your theme styles will render exactly as they appear on the front end, without admin CSS interference.

Natural Media Queries: Viewport units (vw, vh) and media queries will now work relative to the editor canvas, not the entire browser window.

Plugin Stability: Third-party plugin scripts won't accidentally break your editor layout anymore.

⚠️ The core team recently revised the plan: the iframe is auto-enabled only if all blocks in your post are updated to API v3. If you use legacy blocks, the editor will fallback to the old non-iframe mode to prevent breakage.

If you're a developer, it's time to upgrade your block.json to apiVersion: 3. The era of the "un-isolated" editor is officially ending.
