Creating a grid of tiles in bootstrap 3 : <p>I am working on a project and the user asked if they could have something like this.</p>

<p><a href="https://i.stack.imgur.com/Sq9Qr.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Sq9Qr.png" alt="enter image description here"></a></p>

<p>Grid lines are there as a guide.</p>

<p>I understand I could use columns but the item that's tripped me up is the longer image.</p>

<p>Is there a way to have a row that spans many rows?</p>

<p>Or is it best to have columns within columns and then seperate out each element?</p>
