I was wondering if I would be able to use the program Sublime Text to edit HTML code.
Never used it but just checked out the website, looks like it should.
Are you talking about creating a page or viewing source code of another?
I use N++ for my site, works great for HTML.
Sublime text is extremely suited for many languages including html. Notepad++ is okay, but sublime has for more features, which if you spent time learning how to use them, greatly reduces time you spend coding. It is also has nice plugins, including a few for html and css
On the html + css i am in quit a few post, yes
