i think you try to align the content to the right within the div, the div with offset already push itself to the right, here some code and LIVE sample:
FYI: .pull-right
only push the div to the right, but not the content inside the div.
HTML:
<div class="row">
<div class="container">
<div class="col-md-4 someclass">
left content
</div>
<div class="col-md-4 col-md-offset-4 someclass">
<div class="yellow_background totheright">right content</div>
</div>
</div>
</div>
CSS:
.someclass{ /*this class for testing purpose only*/
border:1px solid blue;
line-height:2em;
}
.totheright{ /*this will align the text to the right*/
text-align:right;
}
.yellow_background{
background-color:yellow;
}
Another modification:
...
<div class="yellow_background totheright">
<span>right content</span>
<br/>image also align-right<br/>
<img width="15%" src="https://www.google.com/images/srpr/logo11w.png"/>
</div>
...
hope it will clear your problem
