-webkit-baseline-middle and -moz-middle-with-baseline : <p>When using browsers web inspectors I came across two different and non-standard property for the CSS attribute <code>vertical-align</code>.</p>

<p><code>-webkit-baseline-middle</code> is only available in Chrome while <code>-moz-middle-with-baseline</code> is available on Firefox. The naming is similar but NOT the same.</p>

<p>I couldn't find any information regarding these two on the web. They are not even listed on <a href="https://developer.mozilla.org/en/docs/Web/CSS/vertical-align" rel="noreferrer">MDN</a>.</p>

<p>My questions: </p>

<ul>
<li>Are they part of any standards?</li>
<li>What is the expected behavior when
using them?</li>
</ul>
