The Canvas (highlighted in red below) is the main editing window for an open project. It displays exactly as it would appear on a screen or in a web browser.
Gridlines
The gridlines outside the Canvas help users create more uniform projects by helping them align Widgets in the window.
Gridline sizes can be changed by zooming in or out using Ctrl + Mouse Scroll Wheel Up/Down or by selecting the + or – icons on the Toolbar. To reset zoom, select the maximize icon that is between the + and – icons.
