<p><a href="https://developer.mozilla.org/en-US/docs/Web/CSS">CSS</a> свойство <strong><code>backdrop-filter</code></strong> позволяет вам использовать визуальные эффекты - такие как размытие или смещение цвета фона - за элементом. Так как это применяется ко всему <em>за</em> элементом, чтобы увидеть эффект, вы должны сделать элемент или его фон по крайней мере частично прозрачными.</p>
