Thanks Richard, that makes sense. I also was curious about the size and line-height. I have never seen this short cut before. Although maybe it works for websites, I'm not sure it does for emails. font:14px/18px
Thanks Tatiana, but I am saying on the actual phones. I do see that the litmus tests do that.
But a few phones in the office seem to do it as well. Thanks for your thoughts.
Thanks Jaina, but this is on the actual mobile devices. It seems to happen sometimes and not other times, even though the emails are the same size. And it does happen on other devices, like iPhone 6, and Android.
