HEAD
To get rid of the title_bar, customized titles aren't allowed anymore.
Moved special title for Construction Space pages from &start_page() to new routine &CSTR_pageheader(). Since &start_page() isn't the only routine called to create the page header, the centralized creation of the CSTR page header code can't be currently called in &start_page(). This needs to be done at each place where &start_page() is called.
First changes to get rid of customized page titles:
- Moved CSTR page header code from start_page to new sub routine &CSTR_pageheader()
- Currently keep old header but use &CSTR_pageheader()
- Directly call &CSTR_pageheader() in CSTR related scripts (lonpubdir.pm, lonhomework.pm, structuretags.pm)
(More scripts need to call this routine)
- Added new sub routine &head_subbox() to create head_subbox which contains page related links and functions, etc.
- Added styles for &head_subbox()
(Currently implemented as LC_head_subbox2 to avoid conflicts with code created by lonhtmlcommon::breadcrumbs - will be changed)
Other but related changes:
- Added some breadcrumbs to CSTR
(Only basic calls - links and structure has to be added/revisited)
- Adjusted styles used for breadcrumbs:
- Replaced hardcoded border color by dynamical standard border color
- Removed margin to allow direct concatination with head_subbox
- Added some FIXME comments to mark work in progress
