Answer 1

Add a div element with "container" or "container-fluid" class after form element( <form action="options.php" method="post"> )
like :<form action="options.php" method="post"><div class="container">
...............
</div></form>
OR
like :<form action="options.php" method="post"><div class="container-fluid">
...............
</div></form>
