Vim and Emacs
Vim and Emacs are no development tools, but they offer a range of options for editing HTML and, in fact, a language that you may be using for web development. They both support emphasizing syntax (HTML, PHP, Python, Perl, CSS, and many others) and provide support for editing files on remote computers. Both programs are very versatile and can be widely adapted because they support a number of scripts and extensions to extend their functionality. However, both programs are complex tools and present a learning curve very steep.

But not a single page, why? » Read more: A Review of Linux Web Development Tools
