Flex Resource #1 MDN
Thanks to you Robert, MDN is my go to for learning. There is just so much to glean from their pages. I swear everything I could want to know is on their pages. As usual though I went onto the site, and started reading the flexbox article and got sucked in. After way too much time I was able to tear myself away and get back to the task at hand which is finishing this assignment.
Flex Resource #2 Flexbox Froggy
So I finally took your advice and spent some time on flexbox froggy. I visited there in the spring once after you had mentioned it, and it looked silly to me so I didn't spend any time there. This time I went through all 24 and it helped me to understand how justify-content and align-content switch roles when flex-direction is switched from row to column. I think I'll be going through again when I have time. One drawback to playing it was that I was led into a trap called codepip. There I found a game called Grid Garden among many others that would consume way too much of my time (considering I'm barely keeping up)! So thanks a lot Robert!
Flex Resource #3 Quackit
Quackit is a free learning resource that is add driven. It has a lot of useful tutorials that are basic enough for even me to follow. The site contains tutorials on HTML, CSS, scripting, database, and web hosting. I would say that this falls somewhere between MDN and Flexbox Froggy in the level of learning provided. It's pretty basic but could be useful for someone just trying to wrap their heads around the concept of flexbox. There are code editors imbedded in the tutorial so you can dig in and try things out for yourself also.
Summary
There is a wealth of information available to us for learning anything we want to learn. I think the trick is to find the time to dig in, and learn it. There is help available regardless of what level of learning you're at. When I first started working in the computer field as an intern 20 years ago I was told to go find the answer when I asked my boss a question. That was the best advice I think I ever received. It taught me that the answers are all out there we just need to look. So from the entertaining and instructional games on codeip, to the in-depth learning available on MDN, and everywhere in-between like Quackit, the knowledge that we seek is out there... somewhere.
