Oh come on, are you serious? The site is not intended for web developers who &quot;learn about web dev on their phones&quot;. It&#x27;s an interactive demonstration where you can see and learn about all that flexbox can do. And it&#x27;s done very well. The presentation makes use of multiple panels you need to see at once. Please don&#x27;t make foolish comments about it not working on a phone.<p>Tip: put your phone down. Grab yourself a computer of some description, at the very least a laptop. Take another look at flexboxin5 because it&#x27;s really good.
