Answer 1

Here's a template based on the image. I did an 8 and 4 grid size since bootstrap uses the 12 column system but feel free to alter these numbers as needed.
<div class="container-fluid">
<div class="row">
//this col contains your three card rows
<div class="col-md-8">
<div class="row">
<div class="col"> </div>
</div>
<div class="row">
<div class="col"> </div>
</div>
<div class="row">
<div class="col"> </div>
</div>
</div>
//this is for your shared component
<div class="col-md-4">
<shared-component></shared-component>
</div>
</div>
</div>
