title: Font Size Refuses To Change on iPhone Email
body: <p>I've spent about 4 hours on this HTML email template and no matter what I change the font refuses to increase on the iphone.</p>
  
  <p>I'm at my wits end and would appreciate any help I can get before my mind EXPLODES.</p>
  
  <p>Thanks in advance.</p>
  
  <p>Code and screenshot included below. </p>
  
  <p>I'm simply looking for the font to be bigger enough that it's legible. Just want the body copy to be the size of the heading and the heading to still be about the same amount bigger.</p>
