Notepad++ As HTML Editor Html (hypertext markup language) was the only language that was initially built to be used for web development and design. This was the basic and easiest to learn a language for coding. If you're just looking to paste text, you know TextEdit has a plain text mode you can enable in the preferences. Have tried to use TextEdit in the past, however it always want to do things in formatting the text I am working on that I do not want. I don't know why I like it, but it's definitely better than TextEdit in ways difficult to put down.
