Implementation

The width media feature describes the width of the rendering surface of the output device.

The following media query specifies a style sheet for screen devices with a width less than 480px.

/* css/style.css */

@media screen and (max-width: 480px) {
    #menu li {
        width: 100%;
        float: none;
        margin-bottom: 25px;
    }
}

The following media query specifies a style sheet for screen devices with a width less than 360px and device pixels per CSS pixel less than 1.

The media query feature -webkit-max-device-pixel-ratio is used to specify between the mobile and wearable devices.

/* css/style.css */

@media screen and (max-width: 360px) and (-webkit-max-device-pixel-ratio: 1) {
    #header {
        height: 100px;
        line-height: 100px;
        text-align: center;
    }

    #header #logo {
        width: 150px;
        padding-left: 0;
    }

    #page {
        font-size: 1.5em;
    }

    #menu li .menu-icon {
        width: 75px;
    }

    #menu li .menu-title {
        font-size: 2em;
    }
}

The following media query specifies a style sheet for screen devices with circular UI.

The media query feature -tizen-geometric-shape is used to specify the shape of Tizen devices.

/* css/style.css */

@media screen and (-tizen-geometric-shape: circle) {
    #main {
        margin-bottom: 85px;
    }
}
