+
+<p><strong>Media Queries</strong> - ключевой компонент <a href="/en-US/docs/Web/Apps/Progressive/Responsive">отзывчивого дизайна</a>, который делает возможным для CSS адаптироваться в зависимости от различных парметров или характеристик устройства. Например, media query может применить различные стили если экран меньше определенного размера, или в зависимости от того находится устройство в портретном или альбомном режиме. {{cssxref("@media")}} at-правило используется чтобы задать условия применения стилей к документу.</p>
+
+<p>Кроме того, media query синтаксис используется в других контекстах, таких как атрибут {{htmlattrxref("media", "source")}} элемента {{HTMLElement("source")}}, который может быть установлен в media query строку, чтобы определять нужно или нет использовать этот источник, когда выбирается определенное изображение для использования в элементе {{HTMLElement("picture")}}.</p>
+
+<p>In addition, the {{domxref("Window.matchMedia()")}} method can be used to test the window against a media query. You can also use {{domxref("MediaQueryList.addListener()")}} to be notified whenever the state of the queries changes. With this functionality, your site or app can respond to changes in the device configuration, orientation, or state.</p>
+
+<p>You can learn more about programmatically using media queries in <a href="/en-US/docs/Web/CSS/Media_Queries/Testing_media_queries">Testing media queries</a>.</p>
