Strange CSS effect in Bootstrap. Unintentional indent when showing numerous content divs inside container div

Question

I'm using Bootstrap as CSS framework for a project me and my friend is working on (hence the D&D theme). I have a page where we're displaying a specific users D&D characters. When displaying these characters on the page there is supposed to be four on each row (span4's in a row-fluid). The problem is that there is a strange indentation starting on the second row (see attatched fiddle).

I've been using "Inspect component" in Chrome but I can't seem to get what makes this happen.

Hope I explained the problem somewhat :)

The main "container" (essentially the ) is pasted below:

  <div class="container"><div class="row">
    <div class="span12">
        <h3 class="mycharacters">My characters</h3>
        <a class="btn btn-success btn-small pull-right">
            <i class="icon-plus-sign icon-white"></i> Add character
        </a>
    </div>

Answer 1

That indentation comes from the fact that you're lining up a stack of divs that exceeds the grid limitation of 12 columns per line, so the grid elements past the 12 column mark are indented per design. You can evade this by lining up just 3 .span4 divs per .row-fluid (4x3=12) or targeting that fourth grid element with some css magic and removing the margin, like so:

CSS

.row-fluid > .span4:nth-child(4) {
    margin-left:0;
}

Of course, the nth-child selector is not supported in older browsers (such as IE7-8) but you can replace the CSS with some jQuery if you want to expand support.
