Responsive User Pages
Constituents can now interact with your site using responsive pages that adapt to the size of the device.
Fully-responsive pages from the Standard Page Center include: registration, profile update, opt-out confirmations, and email interests/preferences. The updated pages feature div-based layouts.
To enable, go to Setup > Site Options, then set any of the following Site Options to TRUE:
Email interest or preference page: CONS_EMAIL_PREF_USE_RESPONSIVE_LAYOUT
Email opt-out page: CONS_OPT_OUT_USE_RESPONSIVE_LAYOUT
New constituent registration page: CONS_USER_PROFILE_USE_RESPONSIVE_LAYOUT
Volunteer profile page: CONS_VOL_PROFILE_USE_RESPONSIVE_LAYOUT
By default, the options are FALSE and use the existing table-based layout so that you can test customizations before enablement.
For example, here is a before and after look at the email interest or preference page:
