Bootstrap alignment of button and pagination

Wrap a semantic descriptive class around your button and pagination, such as .navigation-bar and use this to target the margin on the .pagination:

.navigation-bar .pagination {
      margin-top: 0;
    }

You should never override a framework class directly, as it would apply across your entire code base. The alternative is to simply extend the .pagination class:

<ul class="pagination no-margin pull-right"> 

Try adding ths:-

.pagination {
margin: 0px !important;
}

I would go for:

<div class="btn-toolbar" role="toolbar" style="margin: 0;">
      <div class="btn-group">
        <button type="button" class="btn btn-default">1</button>
        <button type="button" class="btn btn-default">2</button>
      </div>

      <div class="btn-group pull-right">
                <ul class="pagination" style="margin: 0;">
                <li><a href="#">«</a></li>
                <li><a href="#">1</a></li>
                <li><a href="#">2</a></li>
                <li><a href="#">3</a></li>
                <li><a href="#">4</a></li>
                <li><a href="#">5</a></li>
                <li><a href="#">»</a></li>
            </ul>
      </div>
    </div>

if you replace the <ul><li.... with buttons , you not need to use style="margin: 0;
