Just put before each output that's too small <font size="9"> and behind </font>.
I will try next week to add a javascript function for that.
Something like:
function fontSizeChange(elem, factor) {
if (!elem) {
return false;
}
else {
factor = factor || 2; // 2 is the default
elem = elem.nodeType && elem.nodeType === 1 ? elem : document.getElementById(elem);
var cur = window.getComputedStyle(elem, null).fontSize,
size = parseInt(cur.replace(/\D+/g,''),10),
unit = cur.replace(/\d+/g,'');
elem.style.fontSize = (size * factor) + unit;
}
}
But therefor all elements (outputs) must have their own id...
Maybe Ale can add the factor variable to the settings. Such way the card only has to be modified once and each user can set that factor optionally.
