Don't use flexbox for overall page layout
The past few weeks I’ve been banging on about flexbox a bit so I’m glad to be able to point out that it’s not the be-all end-all solution. Flexbox ties directly to the content on the page so it will change as the page loads if you use it for the layout.
When I was building this blog I tried to use flexbox for the overall page layout because I wanted to look cool and modern in front of my peers. However, like all of my other attempts to look cool and modern, it didn’t really work.
