After creating some responsive layouts, I'm still not sure whether to use the <center> tag, or style="padding: 0px auto;".
If I use the <center> tag, everything works (Gmail, Oulook/Hotmail, AOL, Thunderbird, Yahoo for the Samsung Galaxy S4) except for Yahoo.
If I enter the padding with auto margins, everything works except for Outlook/Hotmail.
If I try using both, one or the other is ignored, and it seems like it causes more problems.
What do you do to remedy this problem?
