Is there a way to only change the font size of a canvas context without having to know/write the font family.

 var ctx = document.getElementById(\"canvas\").         


        

Answer 1

try this (using jquery):

    var span = $('').css('font', context.font).css('visibility', 'hidden');
    $('body').append(span);
    span[0].style.fontWeight = 'bold';
    span[0].style.fontSize = '12px';
    //add more style here.
    var font = span[0].style.font;
    span.remove();
    return font;
