Opus 2.28 Publisher's Manual
Product Overview
Customising a Paper 
./def/paperstyle.css
We've changed the way the base font sizes are defined in this release, using "px" rather than "pt" which gives a more consistent result across different platforms. If you use the default style sheet you might want to save it before you install 2.28 in case you're unhappy with how your site looks with the new default style sheet. If you are then create your own paperstyle.css in your paper's directory, starting it with
@import url(/php/def/paperstyle.css);
(you will need to change the path if ./php isn't a top level directory in the server tree) then add extra lines to that file to override the values in ./def/paperstyle.css
register_globals
In previous releases Opus required register_globals to be on. This is a classic way of opening up the code to hackers. Opus has now been rewritten to work with register_globals turned off and we recommend that having upgraded to this release you explicitly turn it off, either via .htaccess or whatever control you have of your vhost.
These are now shown with the size and type in brackets after the link. See this page for an example of it in action. If you don't like Opus doing this you can disable this via your style sheet as the text is surrounded by <span class="opus_file_params">...</span> so just the following to your style sheet:
.opus_file_params { display: none; }
