Entering the following while in Vim's command mode will enable auto-completion for HTML language.
To start using the feature, press Ctrl + x followed by Ctrl + o keys while writing HTML syntaxes.

You can use the arrow key to navigate through the list to choose your desired auto-complete suggestion.
To enable auto-complete every time a HTML file is opened, add the following line to your ~/.vimrc;
