+**Update February 2024:**
+The CSS system of this starter was invented by Andy Bell.
+I wrote the following explanation quite quickly after hearing several times that people are confused about normal Tailwind CSS classes not working. In the meantime, Andy has published a [much better and much more detailed explanation](https://piccalil.li/blog/a-css-project-boilerplate/).

 We are using Tailwinds "engine" to generate utility classes on demand, based on our design tokens.
 
 If you have a look at the [tailwind.config.js](https://github.com/madrilene/eleventy-excellent/blob/main/tailwind.config.js), you can see how that is done. For example, we are [deactivating Tailwinds default reset](https://github.com/madrilene/eleventy-excellent/blob/main/tailwind.config.js#L67C1-L69C5).
