CSS content with delay
<p>I'm using CSS <code>content</code> property to add content before an html tag. </p>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-css lang-css prettyprint-override"><code>span::before {
    content: 'content that needs a delay';
}</code></pre>
<pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;span&gt;&lt;/span&gt;</code></pre>
</div>
</div>
</p>

<p>Is there a way to delay the visibility of the content (with CSS)?</p>
