|I'm sorry this answer is coming so late! I hope it's still useful. Dreamweaver is still around, but it no longer reigns supreme. Besides, it's not free and it's expensive.
An excellent code editor is Microsoft's Visual Studio Code. This is separate from the Visual Studio used to develop in C# and Visual Basic, and it's free to use. I'd post a link to download it but the link could change, plus it's hardly hard to find.
Now, to learn web development, I've recently come across a fantastic resource that was there, hiding in plain sight all the time. Forget the paid, online academies and check out the Mozilla Developer Network's free course on web development, starting here: Front-end web developer - Learn web development | MDN[^]
The course has lots of encouraging language while pushing you to think like a software developer. I really can't speak highly enough of it.
