If the canvas is too small for you to see some text or element details, you can enlarge your canvas.
Find and click the 100% button at the top of the canvas, then you can drag the white dot to zoom in and out of the canvas. Minimum 10%, maximum 400%.
There are 4 preset options below, Fit to Screen, Fill the Screen, 100% and 200%.
When the canvas is zoomed in, you can scroll up and down with your mouse to see the entire canvas.
