Addresses the iOS zoom issue inherent to Apple devices
On iOS, font size is very important. We noticed that mobile users will experience a zoom depending on the font size. This is an inherent issue with iOS and mobile's zoom for fields feature. This means all browsers on iOS. To help combat this, you must ensure the font size for any mobile promo is always set to a minimum of 16px. The font size of 16px or grater helps ensure no zoom issues; this means all browsers on iOS.
