Add External Stylesheets/Pens

Any URL's added here will be added as <link>s in order, and before the CSS in the editor. If you link to another Pen, it will include the CSS from that Pen. If the preprocessor matches, it will attempt to combine them before processing.

JavaScript

Babel is required to process package imports. If you need a different preprocessor remove all packages first.

Add External Scripts/Pens

Any URL's added here will be added as <script>s in order, and run before the JavaScript in the editor. You can use the URL of any other Pen and it will include the JavaScript from that Pen.

                //OK let's make our functions.First one is by Hugo Giraudel and gets us maps in maps in...

/// Map deep get
/// @author Hugo Giraudel
/// @access public
/// @param {Map} $map - Map
/// @param {Arglist} $keys - Key chain
/// @return {*} - Desired value

// Now let's make one to flip the text colour
@function theme-text($color) {
  @if (lightness($color) > 55) {
    @return #222; // Lighter bg, return dark color
  } @else {
    @return #fff; // Darker bg, return light color
  }

//Now some mixins, first one is the themer I showed you already
@mixin themer($colour, $key) {

  --#{$key}-event-down: #{mix(#000, $colour, 5%)};

// Next one is gonna read from nested maps and pull out ALL those colours as variables so you can use them in DevTools on the palette view. Heavily cribbed from Sarah Dyan https://gist.github.com/sarahdayan/4d2cc04a636e8039f10a889a0e29fbd9

// -----------------------
// NOW LET'S GENERATE SOME CSS
// -----------------------

//1. grab all the colours and names and sling them on root. We're not themeing these colours just yet,
:root { @include paletize($colors, $join: '-'); }

//2. now themes, set root to brand as backstop theme
:root {
   $brand: #d00489; // Not using your color function as its 
  @include themer($brand, 'brand');
}
//2. make any number of themes and assign to classes

 @each $key, $value in deep-get($colors, "themes") {
  .theme#{$key} {
    @include themer($value, "theme");
  }
}
// todo -- make theme from palette













//-----------------------ignore this, rest just functional display stuff
  body {background:#222; max-width:600px; margin:5vh auto}
// start
.colours {
  display: flex;
