I think I've found most of the CSS for the plug-in in the front.css file.
--IGNORE START--The results of the default—on my installation at least—came out as Courier and just all over the place; it was nothing like the beautiful screen shots in the User Guide at all.
However, I'm having trouble finding the code for the search form. It has a 'pre' tag surrounding the whole code that doesn't seem to make sense to me. I'm not sure if that's standard, but the search form comes out almost deformed looking rather than the nice, neat version shown in the user guide. I'd like to be able to find the CSS and code for this so that it can be style to look more like a library search page rather than a block of code on a page.
It doesn't matter which Theme I use either. The results are the same insofar as the style of the output is concerned. I am sure it's something I've done wrong or missed.--INGORE END--
In short, I'd like to better understand how the plug-in pages/shortcodes are styled so that this can be used for a high quality front end for a small library. Eventually, I'll be trying to figure out how to style a front end search page with results coming in on a different page. Following the user guide didn't seem to have the same results. But first, I'd like to get the CSS worked out so that the search form and the results can match the overall Theme of the site.
Thank you again for a great plug-in and the assistance you've provided.
