@ljames I wouldn't recommend any of those tools for website making :)

You seem to be missing out on the command line ecosystem. Might be worth investigation.

@thinkMoult this post is based on personal experience and those tools work perfectly for me in creating websites :) thank you for your input, though! can you please recommend some links or places get started with your suggestion?

@ljames you recommend 3 things: xampp, geany, and filezilla.

I would recommend natively installing the server and friends separately (Apache, php, mysql, or whatever) than xampp. This teaches you how to set up a production environment properly.

Geany is a very limited text editor. But nothing inherently bad. Personally I prefer vim.

Filezilla suggests ftp (insecure protocol) and lack of version control, and encourages bad deploy practices. I'd recommend SSH, and a CI tool like Jenkins.

@thinkMoult thank you for the info, sounds like an interesting approach depending on one's needs 😄 I'll look into all that more when I have a good amount of time to learn new stuff, but for now I still appreciate the simplicity and ease of use of the tools I use. interesting to see another perspective!
@ljames disclaimer: I have worked as and managed teams of developers building webapps for many years.
@thinkMoult pretty cool, man! sounds like we're working at different scales 😄
