Bootstrap 3 Vertical Alignment Across Multiple Rows and Columns - html

Question

I am new to Bootstrap. I just started a project and came across a challenge regarding vertical alignment with Bootstrap's grid system. Hopefully this community of experts will be able to shed some light and assist with a solution.
To better illustrate the issue, I have taken 4 screenshots (links attached at the bottom) for each of the lg, md, sm, and xs scenarios. I hope the images make sense to you.
The problem is, while the lg scenario looks great and everything is aligned properly, as the viewport changes, the content of the 2 columns start to show misalignment.
Here is the HTML markup:
<div class="container">
<div class="row row-centered">
<div class="col-sm-6 col-md-6 col-lg-6">
<div class="row row-centered">
<div class="hidden-xs hidden-sm hidden-md hidden-lg"></div>
<div class="col-xs-12 col-sm-12 col-md-12 col-lg-12">
<h2>HEADER NUMBER 1</h2>
</div>
<div class="hidden-xs hidden-sm hidden-md hidden-lg"></div>
</div>
<div class="row row-centered">
<div class="col-xs-2 col-sm-2 col-md-2 col-lg-2"></div>
<div class="col-xs-8 col-sm-8 col-md-8 col-lg-8">
<div>
<p>Teaser number 1 - Lorem ipsum dolor sit, interdum consectetur elit. Donec interdum dapibus lectus rhoncus.</p>
</div>
</div>
<div class="col-xs-2 col-sm-2 col-md-2 col-lg-2"></div>
</div>
<div class="row row-centered">
<div class="col-sm-6 col-md-6 col-lg-6">
<img class="img-responsive" src="http://placehold.it/200x200&text=Square" alt="">
<h4>Sub-heading short</h4>
</div>
<div class="col-sm-6 col-md-6 col-lg-6">
<img class="img-responsive" src="http://placehold.it/200x200&text=Square" alt="">
<h4>Sub-heading longer</h4>
</div>
</div>
<div class="row row-centered">
<div class="col-lg-12">
<div>
<p>Link to detailed page 1</p>
</div>
</div>
</div>
</div>
<div class="col-sm-6 col-md-6 col-lg-6">
<div class="row row-centered">
<div class="hidden-xs hidden-sm hidden-md hidden-lg"></div>
<div class="col-xs-12 col-sm-12 col-md-12 col-lg-12">
<h2>HEADER DIFFERENT LENGTH</h2>
</div>
<div class="hidden-xs hidden-sm hidden-md hidden-lg"></div>
</div>
<div class="row row-centered">
<div class="col-xs-2 col-sm-2 col-md-2 col-lg-2"></div>
<div class="col-xs-8 col-sm-8 col-md-8 col-lg-8">
<div>
<p>Teaser number 2 - Lorem ipsum dolor sit amet. Donec interdum dapibus lectus eu rhoncus.</p>
</div>
</div>
<div class="col-xs-2 col-sm-2 col-md-2 col-lg-2"></div>
</div>
<div class="row row-centered">
<div class="col-sm-6 col-md-6 col-lg-6">
<img class="img-responsive" src="http://placehold.it/200x200&text=Square" alt="">
<h4>Sub-heading different</h4>
</div>
<div class="col-sm-6 col-md-6 col-lg-6">
<img class="img-responsive" src="http://placehold.it/200x200&text=Square" alt="">
<h4>Sub-heading 4</h4>
</div>
</div>
<div class="row row-centered">
<div class="col-lg-12">
<div>
<p>Link to detailed page number 2</p>
</div>
</div>
</div>
</div>
</div>
</div>
I have not incorporated any custom CSS yet except for the .row-centered, which is as simple as this:
.row-centered {
text-align:center;}
What should I do to fix the problem? Thank you very much!

Topgun, Hi there. To get this to stay inline with each other.
My approach is to adjust the title font size at 2 media breakpoints.
You can change this to suit what suits you, I went just a little smaller to show the effect here.
I also at a breakpoint add the height value to main text part you have too.
I used min-height here rather than a fixed height. Because when they stack on a small screen the text need room to expand down.
Your code had lost of extra divs and seemed like lots of hidden block padders.
I went through this and removed a lot just to pull it back to what is only needed here for this demo.
Go through the code and see the difference.
What I also added here was col-xs-12 into your img class.
As you will see now when resized down to a small screen size the image goes full width and does not stay to the left with a big space to the right.
To center the text you just need to use the class of text-center once in each of the 2 rows.
Hope that this gets you started for how you want it to look now.
Here is the Fiddle.
