This website is based on Gatsby.js V2 starter which is based on the Photon site template, designed by HTML5 UP.
See a shul-site here.
Install this starter (assuming Gatsby is installed) by running from your CLI:
gatsby new shul-web https://github.com/gbs4ever/shul-web.git
Run gatsby develop in the terminal to start.
The grid on this site was replaced with a custom version, built using CSS Grid. It's a very simple 12 column grid that is disabled on mobile. To start using the grid, wrap the desired items with grid-wrapper. Items inside the grid-wrapper use the class col- followed by a number, which should add up to 12.
