I’m young developer, so I maybe never heard for some tools that you used 
I started with building websites when I was 15, and as I remember I started with Microsoft Publisher (Software from MS Office package) - I didn’t know what is HTML, CSS, or JS, so I was happy with my first site (all was for fun) - code was disaster for sure 
After some time I noticed that I “master” the MS Published and I moved to WYSIWYG software, I don’t remember what version it was.And there first time I met the HTML and CSS but still I didn’t know how to write it.
I have been member of one local development forum, where one guy posted the course by Jeffrey Way called “30 Days to learn HTML and CSS” and that’s how I start.
I used Notepad++ and It was good, after some time, when I improved my skills I switch to Sublime Text which is awesome
And also I learn a lot of meanwhile, I didn’t stay only on HTML and CSS I’m 19 today :))
I think next editor could be Vim
