Save Automatically?

If active, Pens will autosave every 30 seconds after being saved once.

                <h1>A Bug with <code>:has()</code> selector in Safari Technology Preview 137</h1>
<p>It appears that there is a bug with the newly supported :has() selector.</p>
<p>In the example below, only the first <code>
    &lt;a&gt;</code> element should be matched, but the actual result is that even the link without a span element is matched.</p>
<p>Both elements appear with the purple background using the following code:<br> <code>a:has(span) { background: rebeccapurple; }</code></p>
