Add some articles on music box topics

[bryanbraun]

I want to add some "guides" to the site, with simple and detailed instructions on music box topics. Possible topics include:

• How to make a music box.
• How to write a music box song.
• Types of music boxes.
• What is a DIY music box

Technical:

• Start with plain HTML
  • Write it in markdown and do a one-time conversion to HTML using something like this.
  • Keep my "guides" page design SUPER simple
• If it's getting too much of a hassle, use a static site generator:
  • Option 1: 11ty. It looks simple, and the growing popularity would make it good to tinker with.
• Maybe can create a guides.js which loads the components for the mobile nav icon, overlay, and maybe the off-canvas sidebar? A super-minimal JS proof of concept.

Todo:

• [x] Add a section to the site where the guides will live.
• [x] Add one guide to start: What is a DIY music box

Going to call this done since the first guide was published at https://musicboxfun.com/guides/diy-music-box.

If I want to do future guides, they can be tracked in future github issues.
