The Preview window exists by default as a pane on the right side of your screen. It's a live preview of your current code that auto updates whenever you stop typing. You can resize the preview, explore different screen dimensions, block images, or simulate visual impairments.
You can manually refresh the preview using the Refresh Icon button in the top left of the preview or via the command palette.
If you like working with multiple screens, you can pop out the Preview into a separate tab.
This feature is only available on certain plans.
Simply close the preview tab to restore your workspace to the default layout.
