Width of centered menus

Width of centered menus

!important styles are ignored by Outlook when they are inlined. This
rule (.menu[align="center"]) has higher specificity than the other rule
setting the width (table.menu), so it is not necessary to have it
declared as !important. Removing !important means that the style will be
inlined as style="width: 100%" instead of style="width: 100%
!important". The latter is ignored by Outlook, while the first one
works. Ref:
