Use Tooltip and popover

After installing Joomla 3 with T3, I tried using this code to call the tooltip:

Tooltip on left

after this code, I tried it and see if it worked, but did not, so I tried calling the javascript, but no help. I looked all over for help, but I found nothing but just APIs for backend. I need tooltips for FRONTEND of the site. Is there like a special code or something?
