Instead of embedding normalize gutenberg should probably say it's required in the documentation then users could use a newer version of normalize

Need to set up purgecss with Gulp as a new task:

https://www.purgecss.com/#gulp

This is related to the contributing explanation, but is specifically to do with code style, and should (ideally) be used by anyone using stemCSS, rather than just contributors to it. A good example of an existing style guide is the Sass Guidelines.

Interesting project but it's hard to imagine what the result looks like.

Would be nice to have a demo page. Maybe the Foundation kitchen sink? So it would be easy to compare.

Figgo's select has values / placeholder alignment issues.

Here is there patch :
.lu-select-placeholder {
line-height: 1.5 !important;
}

.lu-select-value {
line-height: 1.3 !important;
}

We should checkout why it looks good on prisme but not in Figgo.

Should update the website to display the code used for the examples.
