Always have your element with this attribute:

JavaScript: element.style.fontSize = "100%";

or

CSS: style = "font-size: 100%;"

When you go fullscreen, you should already have a scale variable calculated (scale > 1 or scale = 1). Then, on fullscreen:

document.body.style.fontSize = (scale * 100) + "%";

It works nicely with little code.
