Layout on the web is hard. The reason it is so hard is that the layout methods we’ve relied on ever since using CSS for layout became possible were not really designed for complex layout. While we were able to achieve quite a lot in a fixed-width world with hacks such as faux columns, these methods fell apart with responsive design. Thankfully, we have hope, in the form of flexbox — which many readers will already be using — CSS grid layout and the box alignment module.
In this article, I’m going to explain how these fit together, and you’ll discover that by understanding flexbox you are very close to understanding much of grid layout.
