Hi,
is possible to change the font size on a form header, but of course is an unsupported modification.
you need to add this code on your OnLoad event:
var labels = document.getElementsByClassName('ms-crm-Field-Label-Print');
for (var i=0; i<labels.length; i++) {
labels[i].style.fontSize = '14pt';
}
var values = document.getElementsByClassName('ms-crm-Field-Data-Print');
for (var i=0; i<values.length; i++){
values[i].style.fontSize = '14pt';
}
this code will change also the footer size, is possible to change only the header, but you need to check the parent tree to find if you are inside the header or inside the footer.
Is also possible to do these things with jQuery, but I prefer simple JavaScript to avoid load the library.
