understanding the <carouse-carousel> component

1. put the carousel on your page

   <carouse-carousel arrows dots loop hidden>
     <figure>
       <img src="https://picsum.photos/300/200?1" alt=""/>
       <figcaption>
         <p>hello</p>
       </figcaption>
     </figure>
     <figure>
       <img src="https://picsum.photos/300/200?2" alt=""/>
       <figcaption>
         <p>hola</p>
       </figcaption>
     </figure>
     <figure>
       <img src="https://picsum.photos/300/200?3" alt=""/>
       <figcaption>
         <p>hallo</p>
       </figcaption>
     </figure>
   </carouse-carousel>

2. know how to use the carousel
   <carouse-carousel arrows dots loop hidden>
   • optional boolean attributes
     • [arrows] – enable arrow controls
     • [dots] – enable dot button controls
     • [loop] – enable end-to-end looping
     • [hidden] – hide the component until it has loaded
   • how does the carousel work?
     • you give it html elements as children, and the carousel treats them like slides
     • then the carousel sets the [hidden] attribute on all but the "active slide"
   • programmatically control the carousel
     • carousel.forward(), onto the next slide
     • carousel.backward(), back to the previous slide
     • carousel.jump(0), jump directly to the first slide
     • carousel.childElementCount, getter for the number of children

3. style the carousel and its children

   <style>
     @import url("https://unpkg.com/carouse@0.0.0-dev.4/dist/carouse.css");
   
     carouse-carousel {
       max-width: 300px;
   
       /* carouse custom css properties */
       --focus-outline: 2px solid #0ef;
       --carouse-slate-bg: rgba(255,255,255, 0.1);
       --carouse-arrow-size: 4em;
       --carouse-arrow-bg: rgba(60,60,60, 0.8);
       --carouse-dotbar-bg: rgba(0,0,0, 0.3);
       --carouse-dot-size: 0.8em;
       --carouse-dot-bg: white;
     }
   </style>

   • you'll probably want to import carouse.css because it has some preset styles for figure and figcaption elements
   • every available --carouse- custom property is shown with its default value
   • you'll probably want to set a max-width rule on the carousel
   • the carousel assumes you are setting a app-level * { margin: 0; padding: 0; box-sizing: border-box; }, and if you don't, it might look wacky

okay, so that's how i use it.. how do i install it?

• include the following snippet on your page

  <script type="importmap-shim">
    {
      "imports": {
        "lit-html/": "https://unpkg.com/lit-html@1.0.0/",
        "lit-html": "https://unpkg.com/lit-html@1.0.0/lit-html.js",
        "lit-element/": "https://unpkg.com/lit-element@2.1.0/",
        "lit-element": "https://unpkg.com/lit-element@2.1.0/lit-element.js",
        "carouse/": "https://unpkg.com/carouse@0.0.0-dev.4/",
        "carouse": "https://unpkg.com/carouse@0.0.0-dev.4/dist/register-all.js"
      }
    }
  </script>
  <script type="module-shim">
    import "carouse/dist/register-all.js"
  </script>
  <script src="https://unpkg.com/es-module-shims@0.2.3/dist/es-module-shims.js"></script>

  here's what's going on in this snippet

  • import maps
    • in the above snippet, we provide an import map which locates carouse and its dependencies
    • of course, for the import map, we're using guy bedford's awesome polyfill: es-module-shims
    • if you're from the future, you won't need the -shim's
  • register the carouse component
    • we run import "carouse/dist/register-all.js" to register the <carouse-carousel> component
