I’m trying to start a animation but can’t. I l sketch the animation but I notice after I’m want to ink it I can’t color it what gives and how do you re size the canvas?

Sounds like you’re creating outlines instead of regions. Be sure to check the ‘create region Bline’ check box when using blines. You can fill regions.
If you click on the > button in the top left of the canvas, then Edit then Properties you’ll get a dialog box that allows you to change the resolution of the canvas.
