Coming from sublime I was used to the amazing expand and autocompletion features of Emmet ( Previously known as Zen conding )
It was but natural that I would find the same functionality in Vim ofcourse though unlike sublime it does not work
<Tab> key out of the box
but a simple line in your vimrc would solve that:
let g:user_emmet_expandabbr_key = '<Tab>'
These are the other sane defaults I have added as well so that the tab completion on works in HTML And CSS
let g:user_emmet_install_global = 0
autocmd FileType html,css EmmetInstall
