Creating a centered block of images within a Bootstrap Container - html

Question

I wish to have a group of centered images arranged in a certain way on the homepage of a bootstrap site. To look like the image below:
I want them to remain centered and then shrink when we go to mobile, with the "freeshipping block" not displaying so it just the two horizontal blocks below 750px.
I have set up a Plunker with the code I have

<div class="col-sm-12 customer-greeting">
<p class="intro_text">My opening blurb of text</p>
<div class="offerscontainer">
<div class="offeroftheday">
<a href="product_info.php?products_id=221">
<img class="img-responsive" src="http://i.imgur.com/TQ6gwoO.jpg">
</a>
</div>
<div class="freeshipping">
<img class="img-responsive" src="http://i.imgur.com/Xqw75nl.jpg">
</div>
<div class="24hrdelivery">
<a href="index.php?cPath=53">
<img class="img-responsive" src="http://i.imgur.com/F3JTlas.jpg">
</a>
</div>
</div>
</div>
Should I be adding float classes or should they all be bootstrap col-8-sm, col-4-sm etc?
PS - Should #queries be used in Bootstrap sites or should they pretty much all layout be handled in the HTML code with col-8-sm (bootstrap classes) etc

Answer 1

You can do it like this..
HTML
<div class="container">
<div class="row">
<div class="col-sm-8">
<img class="img-responsive width-100" src="http://i.imgur.com/TQ6gwoO.jpg">
<br>
<img class="img-responsive width-100" src="http://i.imgur.com/TQ6gwoO.jpg">
<br>
</div>
<div class="col-sm-4">
<img class="img-responsive width-100" src="http://i.imgur.com/Xqw75nl.jpg">
</div>
</div>
</div>
CSS
.width-100 { width: 100%; }
You can write col-md-* or col-sm-* depending on your requirement!
