<p>Say we have this responsive design with 3 columns (all 3 are dynamic contents so we don't know their heights)</p>

<p>For desktop:</p>

<p><a href="https://i.stack.imgur.com/55KKT.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/55KKT.png" alt="enter image description here"></a></p>

<p>For tablet (left column moves to the right)</p>

<p><a href="https://i.stack.imgur.com/a5kjw.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/a5kjw.png" alt="enter image description here"></a></p>

<p>What's the best way we can achieve this? (I don't mind using flexbox or other modern css specs)</p>
