</div>

Answer 2

Nothing like good ol' CSS?

.center > form {
  width: 300px; // some amount to prevent using 100% width
  margin: 0 auto;
}

And change .span6 to .span12

Answer 3

The native way for positioning elements in Bootstrap is using offset. I will assume that you are using a 12-column layout.

Bootstrap 2

<div class="container">
    <div class="row">
        <div class="span6 offset3">
            <form>
                ...
            </form>
        </div>
    </div>
</div>

Bootstrap 3

                ...
            </form>
        </div>

<div class="container">
  <div class="row">
    <div class="span9 centred">
      This div will be centred.
    </div>
  </div>
</div>

and to CSS:

[class*="span"].centred {
  margin-left: auto;
  margin-right: auto;
  float: none;
}

Answer 5

Have you tried this?

.center form {
        display: table;
        margin: 0 auto;
    }

This is the easy and fast solution for me.

Answer 6

Both answers posted are valid and work so I upvoted them. Here is another method i did not see posted.

You can center your form by setting it to display:inline-block and center it within the .center container using text-align:center. This way the form will center regardless of width within that container:

CSS

.center {
    text-align:center;
}

.center form {
    display:inline-block;
}
