<p><code>device-height</code> feature is specified as a {{cssxref("&lt;length&gt;")}} value. It is a range feature, meaning that you can also use the prefixed <strong><code>min-device-height</code></strong> and <code><strong>max-device-height</strong></code> variants to query minimum and maximum values, respectively.</p>
