Revision 1.8: download - view: text, annotated - select for diffs
Wed Aug 21 17:18:08 2002 UTC (21 years, 9 months ago) by www
Branches: MAIN
CVS tags: HEAD
Starting to implement common header and color scheme for LON-CAPA handlers
(non-content pages).

Instead of <body bgcolor="#...."><h1>... call

   &Apache::loncommon::bodytag(title,[role],[add_body_parms]);

title: what it says in the header
role (OPTIONAL): override role choice
                 ('admin','coordinator','student','author')
add_body_parms: additional parameters to be put into the body tag, for
                example 'onLoad="init();" or stuff

Colors and layout will likely change in the future, including domain
customization, help function calls, (css?)
