To create a new ANGEL theme:
Line 4)
import url(”/AngelThemes/_global-sah.css”); ( Line 73)
import url(”/AngelThemes/Themes/CLS Cells/theme.css”); (@ Line 75)I created an alternative _global stylesheet called _global-sah.css to do one thing, allow the School of Allied Health’s department graphic in the upper left corner to be 100% opaque.

The original _global stylesheet has the following defined style at line 93:
BODY.section_banner #subject_left { position:absolute;left:0px;top:0px;width:99%;height:55px;background:none transparent no-repeat left top;filter:alpha(opacity=50);-moz-opacity:.50;opacity:.50; }
In the _global-sah file this is updated to leave out the filter style:
BODY.section_banner #subject_left { position:absolute;left:0px;top:0px;width:99%;height:55px;background:none transparent no-repeat left top;}
All style changes are commented and if you create custom work or change files provide some notation for designers who will come after you. I provide comments at the top of the file and right above the changes made.
To customize a theme plan to edit the graphics that exist in your newly created folder in Theme Graphics>themes. If you copied a theme that is missing a graphic you may copy the graphic from another theme. In example each subject.css file will call a main background image but not all Themes use the graphic. The CSS is standard from theme to theme while those themes not using the graphic simply leave the graphic out of the directory.
In order to duplicate the branding create or edit subj-left-sm.gif. The height on this image is 28 pixels. The width will vary but don’t make it wider than the tab width.

The image on the right, subj-right-sm.gif, should be 55 pixels high. The width is 325 pixels.

You may get creative with all the elements that make up a theme. Just be sure to test your settings as you work. Make a change then test. This is especially true of editing the multiple CSS files.
The _print.css file (located in Theme Graphics) may need to be updated on your system to create a print friendly page. The default _print.css file defines very few elements.
