Where is this file?

I have only one CSS folder (using UNI) and it doesn't contain a  "view.css" file. Firebug ID's this file as the one needed for changes I would like, but where is it?

There are a dozen view.css files in use by the various Dolphin modules. 

All you have to do is hover on the file name in firebug, and it will show you the complete path to the file.

EX:  http://domain.com/modules/boonex/photos/templates/base/css/view.css

However... it's not a good idea to modify these core files directly.  Find out which modules view.css file you need to change, and move a copy of it to a new folder as follows:

http://domain.com/modules/boonex/photos/templates/tmpl_uni/css/view.css

You need to add the folder structure shown in red above, then move a copy of view.css to that folder.

If you want a different css for the evo template:

http://domain.com/modules/boonex/photos/templates/tmpl_evo/css/view.css

You can do the same thing with any other module css files  Each template will then use its own view.css and you can customize css per/template without altering core files that may be overwritten by Dolphin upgrade patches.

Your explanation was concise and extremely useful. 

Seems like I've had a new playground opened up for me and a hefty chunk of intimidation of coding eliminated at the same time. Thank you very much Houston!
