I have a problem with Bootstrap 3 columns. When the 12 columns are filled and I keep adding columns they are stacking under them(normal behavior). But if the columns on top of them have different height, a gutter is created. Is there a way of removing it so they can align properly(with no space)? (desktop)
<div class="row content clearfix">
    <div class="col-md-4 itms">
        <div class="user">
            <a href="#" class="thumbnail-custom">
                <img src="logo.jpg" alt="User">
            </a>
            <p>Posted by:</p>
            <p>User</p>
        </div>
    </div>
</div>
And the CSS:
.col-md-4{
margin: 0;
padding: 0;
min-height: 100px;
        }
.itms {
border: 2px solid rgba(54, 21, 21, 1);
}
.user{
padding: 5px 0 0 5px;
max-width: 80px;
border-right: 2px solid rgba(54, 21, 21, 1);
}
.user img{
 margin-top: 5px;
 max-width: 77px;
 max-height: 77px;
 margin: -5px 0 0 -5px;
 border-bottom: 2px solid rgba(54, 21, 21, 1);
 }
