Changing the min height of questionnaire's area

Hello,

I'd like to change the minimum height of the questionnaire which is set by code :

<div id="pf_questionnaire" class="ui-page ui-page-theme-a ui-page-active" data-role="page" data-url="pf_questionnaire" tabindex="0" style="min-height: 746px;" >

Could you tell witch file i have to change ?
Is it possible to customize questionnaire (html,css,...) ?

Best Regards.

The height is calculated automatically (by the jQueryMobile framework), from the inner height of the parent container.
If you make the container higher, so will the questionnaire area.
