Mike Zamansky has another video in his Using Emacs Series up. This time it’s about web-mode. Happily, Org export writes almost all of my HTML for me these days but if you find yourself writing HTML/CSS more than occasionally, web-mode is for you.
As Zamansky says, it’s much better than html-mode. It takes care of the usual syntax highlighting as well as closing tags, folding, indentation, navigation, and other such things. The best place to get more information on the mode is its Web page. In particular, see the section on Native Features for a list of all the things it can do. The Web page also has a nice cheat sheet of the mode’s shortcuts.
Fortunately, web-mode is available from Melpa (and Melpa Stable) so you don’t need to worry about downloading it yourself. Zamansky has a nice beginning configuration for web-mode on the video page so take a look at that as well as the documentation on Web Mode’s web page.
The video is only 7 minutes, 49 seconds long so it shouldn’t be hard to find time to watch it.
