How to remove gutter space for a specific div only - bootstrap

The default Bootstrap grid system utilizes 12 columns with each span having 30px gutter as below. Gutters are the white space between columns. Gutter width seems to be between 20px - 30px. Let's assume it's 30px here.

enter image description here

I want to remove the gutter space for a specific div, so that there will be no gutter space in the row. Each span will be next to each other with no gutter.

The problem is if I remove the margin 30px(gutter) it leaves 360px(12*30) at the end of the row.

Given that I want to remove gutter space for a specific div only. Let's assume that it's for div which are in the

main_content
div.

div#main_content div{
/*
no gutter for the divs in main_content
*/
}


How can I remove the gutter for a specific div without loosing bootsrap responsiveness and not leaving space at the end of the row?

Answer

For Bootstrap 3.0 or higher, see this answer

We're only looking at class .span1 here (one column on a 12 wide grid), but you can achieve what you want by removing the left margin from:

.row-fluid [class*="span"] { margin:0 } // line 571 of bootstrap responsive

Then changing .row-fluid .span1's width to equal to 100% divided by 12 columns (8.3333%).

.row-fluid .span1 { width: 8.33334% } // line 632 of bootstrap responsive

You may want to do this by adding an additional class that would allow you to leave the base grid system intact:

.row-fluid [class*="NoGutter"] { margin-left:0 }
.row-fluid .span1NoGutter { width: 8.33334% }

<div class="row-fluid show-grid">
    <div class="span1NoGutter">1</div>
</div>

You could repeat this pattern for all other columns, as well:

.row-fluid .span2NoGutter { width:16.66667%; margin-left:0 } // 100% / 6 col
.row-fluid .span4NoGutter { width:25%; margin-left:0 } // 100% / 4 col
.row-fluid .span3NoGutter { width:33.33333%; margin-left:0 } // 100% / 3 col
or
.row-fluid .span4NoGutter { width:25% }
.row-fluid [class*="NoGutter"] { margin-left:0 }

* EDIT (insisting on using the default grid)
If the default grid system is a requirement, it defaults to a width of 940px (the .container and .span12 classes, that is); thus, in simplest terms, you'd want to divide 940 by 12. That equates to 12 containers 78.33333px wide.

So line 339 of bootstrap.css could be edited like so:

.span1 { width:78.33333px; margin-left:0 }
  or
.span1 { width:8.33334%; margin-left:0 }
// this should render at 78.333396px (78.333396 x 12 = 940.000752)
