Web design software for "beginners"

[Niko91]

Hi all!
I've just started studying HTML and CSS in these weeks and I was wondering which software should I use for web designing. (It's a kind of hobby, I love it)

I want a software to grow up with, that I can learn well while I'm studying the code and will become my "best friend" for making websites

I know that the most "famous" are Coda 2, Dreamweaver and Sublime Text 2. I've also heard about Flux 4, Rapidweaver and Freeway.
So, what do you recommend to me?

Thank you!
