Re: How to apply theme for custom html pages?
You can designate a theme for Tiki's HTML pages as a group, although not for individual pages as far as I know. To assign a theme:
1) Make sure "Theme control" is checked (turned on) on the Admin/Features page (tiki-admin.php?page=features).
2) Go to the "Theme control" page (tiki-theme_control.php - listed in the left-column Admin menu).
3) On that page, click the "Control by sections" link (to get to tiki-theme_control_sections.php).
4) In the "Assign themes by section" part of the page, use the left dropdown menu to select "html_pages" and the right menu to select the theme you want the pages to have.
That should do it.
