<!DOCTYPE html>
<html lang="en">
<head>

<title>Twitter Bootstrap Popover with placement option Example</title>
<meta name="description" content="Creating Modal Window with Twitter Bootstrap">
<link href="twitter-bootstrap/docs/assets/css/bootstrap.css" rel="stylesheet">
<style> a { margin-left : 400px; } </style>
</head>
<body>
<div class="container">
<h2>Example of creating Popover with Twitter Bootstrap with placement option</h2>
<div class="well">
<a href="#" id="example" class="btn btn-success" rel="popover" data-content="It's so simple to create a tooltip for my website!" data-original-title="Twitter Bootstrap Popover">hover for popover</a>
</div>
<div class="well">
<a href="#" id="example_left" class="btn btn-success" rel="popover" data-content="It's so simple to create a tooltop for my website!" data-original-title="Twitter Bootstrap Popover">hover for popover</a>
