Is leaving completely empty columns in Bootstrap a bad design/programming practice? - html

Question

Here's what I mean.
I have a log in button on the top right of the page, and the title of the page centered in the middle.
However, the only way I found to center the tile on the div, was the center the div itself on the page, which was col-md-9.
I tried using CSS to center the Div, but I couldn't make it work, so the workaround I found was the center the div by using another column before the column where the Title is positioned.
However, this new div is completely empty. I might put a logo in it later on, but I planned for the top right of the page to be empty.
Is there something bad with having empty divs?
Is there a better way to implement this?
Code for reference.
<div class="row">
<div class="col-md-3">
</div>
<div class="col-md-6">
<h1 id="TEXT">OH SNIP</h1>
<br>
</div>
<div class="col-md-3">
<div class="dropdown">
<button id="dpBt" class="dropbtn"></button>
<div id="myDropdown" class="dropdown-content">
<form id="logIn" action="api/users" method="POST">
<div class='form-group'>
<label for='username' class='sr-onl'>Username</label>
<input id='username' type='username' required='' placeholder='Username' class='form-control' name='username'>
</div>
<div class='form-group'>
<label for='password' class='sr-onl'>Password</label>
<input id='password' type='password' required='' placeholder='Password' class='form-control' name='password'>
</div>
<div class='form-group'>
<button id="btnLogin" class='btn btn-block'>Login</button>
</div>
</form>

<input id="btnRegisto" type="button" class="btn btn-block" value="Sign up">
<br>
</div>
</div>
</div>
</div>

You could leave blank columns, but a better approach provided by Bootstrap is to use offsets.
Here is an example from Bootstrap 3.3
https://getbootstrap.com/docs/3.3/css/#grid
<div class="row">
<div class="col-md-4">.col-md-4</div>
<div class="col-md-4 col-md-offset-4">.col-md-4 .col-md-offset-4</div>
</div>
<div class="row">
<div class="col-md-3 col-md-offset-3">.col-md-3 .col-md-offset-3</div>
<div class="col-md-3 col-md-offset-3">.col-md-3 .col-md-offset-3</div>
</div>
<div class="row">
<div class="col-md-6 col-md-offset-3">.col-md-6 .col-md-offset-3</div>
</div>
Here's an example that better fits what your trying to do. Notice the offset for the button.
<form class="form-horizontal" method="post" action="/login/">
<div class="form-group">
<label for="inputEmail" class="col-sm-2 control-label">Email</label>
<div class="col-sm-10">
<input type="email" class="form-control" id="id_username" name="username" value="" placeholder="Email">
</div>
</div>
<div class="form-group">
<label for="inputPassword" class="col-sm-2 control-label">Password</label>
<div class="col-sm-10">
<input type="password" class="form-control" id="password" name="password" value="" placeholder="Password">
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<button type="submit" class="btn btn-default">Sign in</button>
</div>
</div>
</form>
