Zoom and full screen
The editor's bottom bar controls the zoom level of the canvas and toggles full-screen mode. These settings have no effect on the actual rendering of your site: they only serve to make the editor more comfortable to work in.
Set the zoom level
Use the + and - buttons to zoom in or out by steps. The center slider provides continuous adjustment, and the list on the right offers preset levels 100%, 75%, 50%, 25% and 10%.
Zoom in heavily (up to 500%) to precisely align a detail (icon size, a few pixels of spacing). Zoom out to step back on the overall composition of a long page.
The zoom automatically recenters the canvas on the current selection. If no element is selected, it centers on the middle of the visible area.
Full screen
The Full screen icon hides the side panel and the bottom bar to give you the full width of the screen for the canvas. It's useful when you're working on a complex layout or want to preview the rendering without distraction.
Click Exit full screen to restore the usual display.
In full screen, you keep access to the top bar, so you can keep publishing the page, undoing an action or switching pages without going back to the normal view.
