How do I edit my css stylesheet?

Hi there. Apologies if this is the wrong forum and that this is a very stupid question. I am very new to OC and coding in general but I have been tasked with designing my shop's new website. I am familiar with OC's admin panel but further editing of the css style sheet eludes me. From what I can tell, I need some sort of tool to access the website's root directory so that I can edit the style sheet. I thought this tool was an FTP client but I cannot find the tab for FTP in OC's admin panel so I've hit a brick wall. I have read about something called Cpanel as well but again, I have almost no idea what this is.

Any help is appreciated. I am on OC ver. 3.0.2.0

FTP functionality has been removed in v3.x releases. As for the stylesheet: catalog/view/theme/<your_theme>/stylesheet/stylesheet.css file. However, each times you edit a file, ensure to apply these steps: viewtopic.php?f=176&p=731764#p718325

I'm sorry but where do I go exactly to access these folders? Is it in my OC control panel? Do I need some sort of program to do it?
