Simple Login Page using Bootstrap

Below is a example of a Simple minimal User Login page designed using Twitter's bootstrap.

We have a user login id and password filed with a Login Button

The container that holds these elements is aligned at the middle of the page.

<div class="container">
    <div class="row">
        <div class="form_bg">
            <form>
                 <h2 class="text-center">Login Page</h2>

                <br/>
                <div class="form-group">
                    <input type="email" class="form-control" id="userid" placeholder="User id">
                </div>
                <div class="form-group">
                    <input type="password" class="form-control" id="pwd" placeholder="Password">
                </div>
                <br/>
                <div class="align-center">
                    <button type="submit" class="btn btn-default" id="login">Login</button>
                </div>
            </form>
        </div>
    </div>
</div>
