The documentation states:
"Heavy use is made of a style sheet, styles.css. If you make edits, copy the local version to [jsp.custom-dir]/dspace/modules/jspui/src/main/webapp/styles.css, and it will be used automatically in preference to the default, as described above." https://wiki.duraspace.org/display/DSDOC5x/JSPUI+Configuration+and+Customization
Currently the JSPUI header does not include style.css by default: https://github.com/DSpace/DSpace/blob/master/dspace-jspui/src/main/webapp/layout/header-default.jsp I included it, but the layout result is poor (or at least strange). Is it in there for legacy reasons or am I missing something?
I would gladly like to revise the documentation, but it seems that regular users do not have write access.
