I consider myself a practical strategist and as such feel like it's important to be able to prototype so that I can quickly express my ideas. I mostly use non code tools such as InVision, Flinto and Principal to prototype because diving into code too early can be a distraction before you really have defined the product's value proposition and gone through a proper discovery.
From time to time, though, I need to roll up my sleeves and dive in. I have done a lot of front end work over the years and while it's not how I make my living, I do it because it's fun to experiment and get things done. Plus it's empowering.
I have been recently working with a startup on product and content strategy (it's a learning platform for novice investors) and we needed a landing page. The founder's team was busy doing other stuff so I thought what the heck I'll just do it.
I've used UIKit and MaterialUI quite a bit so I fired up Sublime and dove in. In just a few hours I had a fully responsive landing page designed in code (btw don't recommend this as a general approach).
The really cool thing about doing this was my chance to use Flexbox for the first time.
One of the powerful things about Flexbox is the control it gives you to dynamically change the display order of content on the page. In this case the landing page has an alternating layout. When you shrink it down to a mobile view by default it means the stacking order of elements would be inconsistent.
With Flexbox I was able to re-order the stacking of elements (and content) in the mobile view so that the section description would always be on top of the image. It only took 5 minutes to make it work.
The whole landing page with Flexbox dynamic responsive layouts, mailchimp subscribe integration and JQuery scroll animation took @3 1/2 hours. Not bad for a strategy guy who likes to tinker.
I still consider myself a strategist through and through, but it's nice to know I can roll up my sleeves from time to time and "get dirty". Plus it's always fun to add a new thing like Flexbox to my ever expanding toolbox.
