This project is a part of *-mixins, with goal to provide a better CSS experience to the React infected people.

Demo

Theory

Atomic (or Functional) css is quite good methodology, but as long it solves many issues - it also introduces a new one.

You can create a Button, and you can describe how it must look like.

<button class="bg-purple f6 br3 ph3 pv2 white hover-bg-light-purple">
  Button Text
</button>

But you will soil HTML code with details of behavior. Both css driven by html or html driven by css is bad. Something in the middle - BEM - is also not very usable.

You can use LESS to combine all modificators, to have single control point

.bg-purple{
  .f6;
  .br3; 
  .ph3; 
  .pv2; 
  .white;  
  .hover-bg-light-purple;
}

But result CSS will be HUGE.

But you can use client-side CSS framework, to do the same. To get a Component. And you will love the result.

const Button = styled.button`
  ${f6};
  ${br3}; 
  ${ph3}; 
  ${pv2}; 
  ${white};  
  ${hover-bg-light-purple};
`

Limitations

*-Mixins can provide only mixins. A single class, style, or an atom.

If some library has selector like:

  .someclass .someanotherClass

*-Mixins will provide only .someclass, and adding .someanotherClass to the html markup - is your duty. No magic.

Naming conversion

One cannot use real css names in js, so we have to convert names to a js-friendly format:

• ".class" becomes class
• "tag" becomes tag_tag
• "#id" becomes $id
• "hover-bg" becomes hover_bg
• "block--element" becomes block$$element
• ".class.anotherclass" becomes class_and_anotherclass

Prior art

Idea was found here - https://adamwathan.me/css-utility-classes-and-separation-of-concerns/

This is just an adoptation for a different style of CSS generation.
