A boilerplate with the setup I prefer when starting a new Jekyll site.

Includes jQuery 3.3.1, Bootstrap 4, Google/Typekit webfont loader, Font Awesome 5 svg/js.

In _config.yml

theme-color: Use this to set a color in your head metadata for favicons and theme.

ga-id: Place your Google analytics ID here.

share-image: is the location of an image that will be used when the url of the page is shared on Facebook or Twitter. Location is already set to img folder in assets, simply write the subpath from there. Example:

---
title: My Title
description: My Description
share-image: max-wirt.jpg
---

Use {% include video.html ratio="16by9" url="https://www.youtube.com/embed/Sjx9oSJDAVQ" %} for responsive video embeds.

Works for YouTube and Vimeo videos. ratio is the aspect ratio of your video. Can be "1by1", "4by3", "16by9", or "21by9". url is the url in the embed code for the video.
