Well, I would say that vertically centering a thumbnail to the left of a block of text would certainly be easier with flex box. My previous solution would have been:<p><pre><code>    .container { position: relative; }
    .thumbnail { position: absolute; margin: auto 0; width: w; height: h; margin: auto 0; top: 0; right: 0; bottom: 0; left: 0; }
    .summary { padding-left: w; min-height: h; }
</code></pre>
With flexbox that becomes:<p><pre><code>    .container { display: flex; }
    .thumbnail { align-self: center; }
</code></pre>
There are a lot fewer traps and design is a lot more scalable in that you don&#x27;t have to worry per se about width and height.
