* <pre>
* @media all and (application-dpi: 240) and (os-platform: "Android")
* {
* s|Button { color: 13; }
* }
* </pre>
*
* There are 3 media query conditions:
* <ol>
* <li>{@code all}<br>
* key is null, value=all</li>
* <li>{@code application-dpi: 240}<br>
* key=application-dpi, value=240.</li>
* <li>{@code os-platform: "Android"}<br>
* key=os-platform, value="Android".</li>
* </ol>
* Media query conditions are key-value pairs. There are also special "key-less"
* conditions like {@code all}.
