How to make your pages not 100% wide by default
I have been watching different implementations of CANVAS and I see that the ideal is to have the maximum width of the pages not at 100%, but at a percentage like 80%. This way, it doesn't look bad when the screen resolution is FULLHD.
I haven't found how to change this parameter.
I have seen implementations that have a different width than 100%
And other implementations, like mine and this one, where the width is always 100% and I don't know where to change that parameter.
I would like a 80% by default.
