<h1>Writing inline demos</h1>
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
<p>There are some issues with <a class="pattern-link" href="https://heydon.github.io/infusion/patterns/coding/codepen-embedding/"><svg class="bookmark" aria-hidden="true" viewBox="0 0 40 50"><use xlink:href="#bookmark"></use></svg>CodePen embedding</a>, like them not working offline. They also come with CodePen branding, which will clash with the pattern you’re trying to illustrate.</p>
|
|
|
|
<p><strong>Infusion</strong> offers another option: a special <code>demo</code> shortcode that allows you to write HTML, CSS, and JavaScript directly into the markdown file. The outputted demo is encapsulated using Shadow DOM, so you don’t have to worry about broken styles and global JS.</p>
|
|
|
|
<p>Here’s the example code for an inline demo of a toggle button:</p>
|
|
|
|
<pre class="language-html line-numbers"><code class="language-html" data-codeblock-shortcode>
|
|
{{<demo>}}
|
|
<button aria-pressed="false">Toggle Me</button>
|
|
<style>
|
|
button {
|
|
background: DarkCyan;
|
|
color: white;
|
|
border: 0;
|
|
font-size: 1.5rem;
|
|
padding: 0.5em 1em;
|
|
border-right: 5px solid #000;
|
|
border-bottom: 5px solid #000;
|
|
}
|
|
|
|
[aria-pressed="true"] {
|
|
border: 0;
|
|
border-top: 5px solid #000;
|
|
border-left: 5px solid #000;
|
|
}
|
|
</style>
|
|
<script>
|
|
var toggle = demo.querySelector('[aria-pressed]');
|
|
|
|
toggle.addEventListener('click', (e) => {
|
|
let pressed = e.target.getAttribute('aria-pressed') === 'true';
|
|
e.target.setAttribute('aria-pressed', !pressed);
|
|
});
|
|
</script>
|
|
{{</demo>}}
|
|
</code></pre>
|
|
|
|
|
|
<p>Note the <code>demo.querySelector</code> on line <code>21</code>. <strong>Infusion</strong> automatically provides <code>demo</code>, representing the root node of the demo. It’s like the <code>document</code> keyword but for a demo’s subtree.</p>
|
|
|
|
<p>Here’s a live demo of… the demo:</p>
|
|
|
|
|
|
|
|
|
|
<div class="demo-container">
|
|
|
|
<demo-elem34e756fc953627a51e20255208dbdb57 class="demo" id="demo-34e756fc953627a51e20255208dbdb57"></demo-elem34e756fc953627a51e20255208dbdb57>
|
|
|
|
|
|
<template id="template34e756fc953627a51e20255208dbdb57">
|
|
|
|
<button aria-pressed="false">Toggle Me</button>
|
|
<style>
|
|
button {
|
|
background: DarkCyan;
|
|
color: white;
|
|
border: 0;
|
|
font-size: 1.5rem;
|
|
padding: 0.5em 1em;
|
|
border-right: 5px solid #000;
|
|
border-bottom: 5px solid #000;
|
|
}
|
|
|
|
[aria-pressed="true"] {
|
|
border: 0;
|
|
border-top: 5px solid #000;
|
|
border-left: 5px solid #000;
|
|
}
|
|
</style>
|
|
<script>
|
|
var toggle = demo.querySelector('[aria-pressed]');
|
|
|
|
toggle.addEventListener('click', (e) => {
|
|
let pressed = e.target.getAttribute('aria-pressed') === 'true';
|
|
e.target.setAttribute('aria-pressed', !pressed);
|
|
});
|
|
</script>
|
|
|
|
</template>
|
|
<script>(function() { ShadyCSS.prepareTemplate(template34e756fc953627a51e20255208dbdb57, 'demo-elem34e756fc953627a51e20255208dbdb57'); var script = template34e756fc953627a51e20255208dbdb57.content.querySelector('script'); if (script) { script.textContent = `(function() { var demo = document.querySelector('demo-elem34e756fc953627a51e20255208dbdb57').shadowRoot; ${script.textContent} })()` } class DemoElem extends HTMLElement { connectedCallback() { ShadyCSS.styleElement(this); this.attachShadow({mode: 'open'}); this.shadowRoot.appendChild(template34e756fc953627a51e20255208dbdb57.content.cloneNode(true)); } } customElements.define('demo-elem34e756fc953627a51e20255208dbdb57', DemoElem); })();</script>
|
|
</div>
|
|
|
|
|
|
<h2 id="captioned-demos">Captioned demos</h2>
|
|
|
|
<p>It’s possible to give your demo a caption using an accessible <code><figure></code> and <code><figcaption></code> structure. All <em>you</em> need to do is supply a <code>caption</code> attribute. For example:</p>
|
|
|
|
<p><pre class="language-html line-numbers"><code class="language-html" data-codeblock-shortcode>
|
|
{{<demo caption="A basic button element">}}
|
|
<!-- demo code here -->
|
|
{{</demo>}}
|
|
</code></pre>
|
|
</p>
|
|
|
|
<p>Along with the standard <code>figure</code> shortcodes (described in <a class="pattern-link" href="https://heydon.github.io/infusion/patterns/media/including-images/"><svg class="bookmark" aria-hidden="true" viewBox="0 0 40 50"><use xlink:href="#bookmark"></use></svg>Including images</a>), demo figures are numbered automatically according to their order in the page. You can use markdown syntax in the caption text value.</p>
