    13 <p>The term <i>theme</i> refers to a set of design elements installed in
       
    14 a package in a mobile device based on the Symbian platform that determines
       
    15 the visual appearance of the UI. Themes, also known as <i>skins</i>, only
       
    16 affect the visual appearance of the UI, the underlying architecture, interaction
       
    17 style, language settings, and general functionality are not affected.</p>

    19 <p> The Symbian platform provides an API to allow you to support themes
       
    20 in your applications. Although a mobile device based on the Symbian platform
       
    21 can contain several themes, mobile device users can only activate one theme
       
    22 at a time. When a new theme is activated, the appearance of all applications
       
    23 that support themes is altered.</p>
       
    24 <p>The following list contains some of the UI design elements that can
       
    25 change:</p>
       
    26 <ul>
       
    27 <li><p>display background</p></li>
       
    28 <li><p>color palette</p></li>
       
    29 <li><p>highlights</p></li>
       
    30 <li><p>pop-up window appearance</p></li>
       
    31 <li><p>ring tones</p></li>
       
    32 <li><p>common component look and feel</p></li>
       
    33 </ul>
       
    34 <p>Themes also support SVG-T graphics, which allow them to be scalable.
       
    35 Themes can contain bitmaps or SVG graphics or a mixture of both. </p>
