Each link leads to the css file that can be edited in the CSS Styles Editor in the Admin Panel (Dolphin 6.0.003). These are in the same order as they appear in the panel.
You need to remember to set these files to writable before editing them with the Styles editor. Using your FTP client change the file attributes from 644 to 666. This can usually be done by right clicking the file. They are located in yoursite.com/templates/tmpl_uni/css . Do not forget to change them back to non-writable when you are finished.
There are also .css files located in yoursite.com/templates/base/css that are not able to be edited from the CSS Styles Editor. They are called in from their corresponding counterparts in the yoursite.com/templates/tmpl_uni/css files. For example the following line in the rate.css file: @import url(../../base/css/rate.css);. I do not know the reasoning behind this structure.
I would like to add to this document the name of the file that uses each .css file. I would also like to see screen captures of those files by users and how they have made changes they liked.
