I use bootstrap and am trying to center a div(span7) like that:

<div class="row-fluid">
    <div id="main" class="span7">
        Lorem ipsum dolor sit amet
    </div>
</div>

my css code is:

#main{
    margin:0px auto;
}

But it isn’t set at the center. How can i set center?

EDIT

span7 is now col-7 in Bootstrap 4 and row-fluid is deprecated(Instead of this, use container-fluid and row).

    Twitter’s bootstrap .span classes are floated to the left so they won’t center by usual means. So, if you want it to center your span simply add float:none to your #main rule.

    CSS

    #main {
     margin:0 auto;
     float:none;
    }
