Probably not because the site doesn't know where the centre is vertically (since it's very adjustable)!  Alternatively, if you want some space at the top instead, consider adding margin-top:60px in the style tag of the first line!  Like this:

<div class="mx-auto" style="font-size:11px; letter-spacing:0.5px; max-width:420px; margin-top:60px">

Feel free to adjust the 60px to a different number!  Hope this helps! <3
