First thing was to work out how to generate and download the images. This turned out to be relatively easy with a combination of dom-to-image and FileSaver. To generate a list of the Font Awesome icons output in the search, I grabbed the JSON config, did a little bit of manipulating in Sublime and used Eleventy's global data files to use that data when building the site.
I wanted to keep everything as simple as possible; no crazy build scripts and as few files as possible. I used Water.css for the base css and the rest of the css is in a
style tag in the
head (is that legal?). I also learnt that there is a
type="color" input - although I might replace this at some point because it's not particularly nice on mobile Safari.
You can also share you pot images with a link like this. I initially used url hashes to keep the url updated all the time, but when sharing these to Twitter they get stripped out so I switched to using query strings instead.
