I'm a huge fan of Visual Studio Community or Visual Studio Code depending on your needs. I used to use some software called PhpDesigner which I didn't like much but it got the job done. I then moved onto PHPStorm, and stopped using their software after they changed their licensing model. I tried out VSC and found I really liked it. Stable, doesn't slow down, pretty customizable.
I've always used dreamweaver. Before paying for it, I used a lot of other programs, but dreamweaver was just the most reliable and the constantly updating features have been getting really good in these last few years.
I use Notepad++ and HTML and CSS
my g/f wonders why i spend so much time on it.
She says why don't I use Dreamweaver or Google Docs Website Builder or Squarespace.
I try to tell her that I want complete control.
