I've got a couple of wordpress sites up and running using the Prosense theme.
I want to make further changes to the theme, e.g. convert from fixed to fluid, change sidebars, and a bunch of other things. Or I may even change themes.
Because I'm still a newbie at this, I tend to work by trial and error, and sometimes when I make changes I end up with a mess of new problems to fix.
As I don't want my visitors to land on the site in the midst of these changes, I'd like to be able to work on an offline version that I could simply upload when done.
I saw somewhere that developers often work on WordPress offline, from installations on their computers.
Is this possible when working on a Mac running 0S 10.4.11?
Is a lot of hard disk space required?
