sorry i missed your question, but to work on your site offline, you can download your files to your computer and just edit them there, using a text editor to open your html files. you can still use your browser to look at the pages, but you dont actually need internet!
update 1: actually can post now, woohoo. got up to the CSS part of the tutorial, and found out how to use the style.css file. sweet! also found the usemap command useful for the Funpage:tm:, actually became fun lmao.
i LOVE flowerbob <33333 thank you
