" Description: html5 (and html4) indenter " Changed By: Brian Gershon " Last Change: 30 Jan 2011 " " 1. Started with vim72 html indent file authored by Johannes Zellner (below) " 2. Added html5 list as described here: " http://stackoverflow.com/questions/3232518/how-to-update-vim-to-color-code-new-html-elements " 3. Added this to a fork of https://github.com/othree/html5.vim " which already provides nice html5 syntax highlighting.
