<form>
    <div class="form-group">
        <label>User Name</label>
        <input class="form-control" 
            type="text" 
            placeholder="Enter your User Name">
    </div>

    <div class="form-group">
        <label>Password</label>
        <input class="form-control" 
            type="password"
