Style edting not consistent with Firebug

RE-POSTED FROM STYLE SHEET EDITING TOPIC IN ‘HOW TO AND TROUBLESHOOTING’. See post for relevant responses.

My site… https://036daf1.netsolhost.com/s47a/

First, I am not as code literate as most but I am working on my second site so I’m getting better. I choose the Eino theme because it is extremely flexible in its style options. But a couple elements I would like to further customize.

Desired outcome:
1. To make breadcrumb nav bar disappear.
2. To have text/widget boxes with transparent back-grounds, borders & no box-shadows.

What I’ve done…
Using Firebug:
1. I have found and deleted/previewed the breadcrumb bar. LOOKS GREAT!
2. I have found and previewed the background-color #FFFFFF as ‘transparent’. LOOKS GREAT!
3. I have found and previewed the box-shadow at 0px. LOOKS GREAT!

Everything looks beautiful and just how I want it. So with Filezilla I download the Style.CSS AND Style.min.css to edit with Dreamweaver.

Problems:
1. The line #s indicated in Firebug are not consistent.
2. I am unable to find any reference to back-ground colors or box-shadows as previously viewed in fire bug.
3. I eventually find and delete the ‘breadcrumb’ code (as seen in Firebug)and tested it. My site was a mess so I revert back.

What am I missing here?
Thanks
