@andersponders shouldn't we split this check in case only one dimension is set in the style?

You could, but I would say if the user is explicitly setting one through CSS, it seems more natural to let the other get handled that way too. im too lazy to make an example, but in my case I was setting height to be 70% of the container, and in that case i probably don't want the library to set width to be static 200px

i should add this is with responsive=false, another option is instead check if responsive is set

canvas.style.height = height + 'px';
canvas.style.width = width + 'px';
}
};
