Patterns and concepts

Less JavaScript

All config can be putted to the HTML. For example:

<section
  data-carousel="carousel"
  data-carousel-visible-slides="3"
  data-carousel-autoplay="2000"
  data-ovo-auto
>

🥚 attribute name

Every 🥚 has its own root HTML attribute. The name follows the following pattern:

default	🥚 name in kebab case	attribute in kebab case
data-ovo-	spin-images
data-ovo-	spin-images	-debounce="NUMBER"
data-ovo-	spin-images	-quantity="NUMBER"
data-ovo-	scrollable-sticky
data-ovo-	carousel
data-ovo-	carousel	-visible-slides="NUMBER"

Auto play

The attribute data-ovo-auto starts automatically any 🥚. Just put this HTML attribute to the respective the tag that you want the effect, for example: <div data-ovo-anchor="to-anchor" data-ovo-auto>.

Global module

The 🍳 Ovos library is putted to the global object (window) and can be used everywhere. Below an example of the 🥚 Sticky Header made only on HTML.

<html lang="en">
<head>
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <meta http-equiv="X-UA-Compatible" content="ie=edge">
  <title>OVO - Sticky Header</title>
  <style>
    body {
      font-size: 30px;
      font-family: Verdana, Geneva, Tahoma, sans-serif;
      margin: 0;
      min-height: 300vh;
      background-color: lightblue;    }

    main,
    header {
      padding: 40px;
    }

    header {
      background: black;
      color: white;
    }
  </style>
</head>
<body>
  <header data-ovo-hs="header" data-ovo-auto>
    HEADER
  </header>
  <main>
    <p>You can scroll down and the header will scroll together.</p>
    <p>Emmediately when you scroll up the header will appear again.</p>
  </main>
  <script src="https://unpkg.com/ovos@1.2.4/dist/ovos.js"></script>
</body>
