Set min-height data-role="page"

Set min-height data-role="page"

I noticed that although I have a very small content, the height of the page is always 333px. you can set it?

  1. <div data-role="page" data-url="/Login_prova.aspx" tabindex="0" class="ui-page ui-page-theme-a ui-page-active" style="min-height: 333px;">

I work with small screens and 333px are too many.
what is the best practice to change it?
