Вращающийся слайдер изображений
Ассиметричный слайдер изображений в котором при смене картинок происходит их небольшой поворот. Добавлена опция автозапуска и прокрутка с помощью колесика мыши.
В слайдере будем использовать плагин jQuery 2D Transformation Plugin для поворота изображений и плагин jQuery Mousewheel Plugin для использования колесика мыши.
Подключаем необходимые файлы:
<script type="text/jаvascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js"></script>
<script type="text/jаvascript" src="js/jquery.transform-0.9.3.min_.js"></script>
<script type="text/jаvascript" src="js/jquery.mousewheel.js"></script>
<script type="text/jаvascript" src="js/jquery.RotateImageMenu.js"></script>HTML
Во-первых создадим оболочку вокруг всех наших элементов слайдера:
<div class="rm_wrapper">
...
</div>Внутри оболочки поместим контейнер со списком, масками и угловыми элементами, заголовок и скрытый DIV содержащий всё множество изображений.
<div id="rm_container" class="rm_container">
<ul>
<li data-images="rm_container_1" data-rotation="-15">
<img src="images/1.jpg"/>
</li>
<li data-images="rm_container_2" data-rotation="-5">
<img src="images/2.jpg"/>
</li>
<li data-images="rm_container_3" data-rotation="5">
<img src="images/3.jpg"/>
</li>
<li data-images="rm_container_4" data-rotation="15">
<img src="images/4.jpg"/>
</li>
</ul>
<div id="rm_mask_left" class="rm_mask_left"></div>
<div id="rm_mask_right" class="rm_mask_right"></div>
<div id="rm_corner_left" class="rm_corner_left"></div>
<div id="rm_corner_right" class="rm_corner_right"></div>
<h2>Angelina Jolie Voight</h2>
<div style="display:none;">
<div id="rm_container_1">
<img src="images/1.jpg"/>
<img src="images/5.jpg"/>
<img src="images/6.jpg"/>
<img src="images/7.jpg"/>
</div>
<div id="rm_container_2">
<img src="images/2.jpg"/>
<img src="images/8.jpg"/>
<img src="images/9.jpg"/>
<img src="images/10.jpg"/>
</div>
<div id="rm_container_3">
<img src="images/3.jpg"/>
<img src="images/11.jpg"/>
<img src="images/12.jpg"/>
<img src="images/13.jpg"/>
</div>
<div id="rm_container_4">
<img src="images/4.jpg"/>
<img src="images/14.jpg"/>
<img src="images/15.jpg"/>
<img src="images/16.jpg"/>
</div>
</div>
</div>DIVы масок и углов будут абсолютными элементами, которые будем помещать над слайдером.
Далее добавим элементы навигации и управления автозапуском.
<div class="rm_nav">
<a id="rm_next" href="#" class="rm_next"></a>
<a id="rm_prev" href="#" class="rm_prev"></a>
</div>
<div class="rm_controls">
<a id="rm_play" href="#" class="rm_play">Плей</a>
<a id="rm_pause" href="#" class="rm_pause">Пауза</a>
</div>CSS
Сначала установим некоторые стили и определим свойства для body (если у нас будет другой цвет фона, то придется изменять и цвет фона и границ некоторых элементов самого слайдера).
