Real presentation sample

Getting started

Talkie.js contains two of the CSS and one of JavaScript.

  • dist/talkie.min.css
  • dist/talkie.min.js
  • dist/talkie.theme-default.css

Next code is the simplest example.

<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="./dist/talkie.css">
<link rel="stylesheet" href="./dist/talkie.theme-default.css">
</head>
<body>

<!-- Pure HTML style -->
<tk-slide layout>
  <h1>Slide 1</h1>
</tk-slide>

<!-- Markdown style ( require `type` attribute ) -->
<tk-slide layout type="text/x-markdown">
# Slide 2
</tk-slide>

<script src="./dist/webcomponents-loader.js"></script>
<script src="./dist/talkie.js"></script>
<script>
window.addEventListener('WebComponentsReady', function(e) {
  document.body.className += ' webcomponents-ready';
  talkie.run();
});
</script>
</body>
</html>

If you use the code highlighting, you must load these files.

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/highlight.js/9.12.0/styles/monokai-sublime.min.css">
<script src="//cdnjs.cloudflare.com/ajax/libs/highlight.js/9.12.0/highlight.min.js"></script>

Slide ratio

The default slide is 4:3 (width 1024px, height 768px). If you execute it with the following code, the slide ratio becomes 16:9 (width: 1366px, height 768px).

talkie.run({wide: true});

Scrolling direction

The default scrollable direction is vertical. If you execute it with the following code, the scroll direction becomes horizontal.

talkie.run({horizontal: true});

Backface image & filter

You can add backface attribute into each slides. Image path that you specify in the backface attribute will be the background of when the slide is displayed.

<tk-slide layout
          backface="background-image.jpg"
          backface-filter="blur(1px) brightness(.8)">

  <h1>Title</h1>
  <p>foo, bar, baz, qux...</p>

</tk-slide>

backface-filter attribute is applied to the background image as CSS Filters. But using this, will occur side effect significantly to performance on mobile device.

All options

interface TalkieOptions {
  wide?: boolean; // default: false
  horizontal?: boolean; // default: false
}

talkie.run(options);

FullScreen mode

When you press the f will be a full-screen mode. f or Esc Press and then exit.
