Emacs HTML Tips
This page is a tutorial on working with HTML.
Which HTML Mode To Use?
html-mode for Simple HTML (in emacs)
When you open a file ending in “html”, it'll automatically open in
html-mode. This is a basic HTML mode. It is writen by SGML/XML expert James Clark, in 1990s.
nxml-mode for Valid XHTML/XML (in emacs)
If your code is valid XML, you should use
nxml-mode. “nxml-mode” is a mode for editing XML documents, also written by SGML/XML expert James Clark, in 2000s. It has the feature of real-time XML validation.
nxml-mode comes with emacs 23.1.1, but is not the default mode loaded when you open a file ending in “.xml”. (This is fixed in 23.2.x) To load “nxml-mode”, just type 【Alt+x nxml-mode】. To set emacs to always use nxml when files ending in “.xml” is opened, see:
Emacs: Set File to Open in a Major Mode, or simply set a alias like this:
(defalias 'xml-mode 'nxml-mode).

- web-mode http://web-mode.org/ is new, becoming popular around 2012. You might try it. Install it from MELPA. 〔►see Emacs: How to Install Packages Using ELPA, MELPA〕
- html-helper-mode 〔http://www.emacswiki.org/cgi-bin/wiki/HtmlHelperMode〕
- nXhtml mode 〔http://www.emacswiki.org/emacs/NxhtmlMode〕. (nXhtml mode is based on nxml mode, but as of mid 2009, i did not find this package robust.)
