Bootcamp II is a wordpress theme (as well as an inside joke) designed to suit the needs of foothillschurch.com. It makes use of webpack, Babel, Sass, Tailwind, Browsersync, PostCSS, ESLint, Stylelint, Prettier and more. It is meant for that site, but if you can use it by all means go for it.
I would recommend compressing any images that you can, especially larger background ones.
For example,
topography-salty.pngandtopography.png. The screenshot below shows how much weight was saved with a simple tool like compressor.io.
