Сегодня сделаем на чистом CSS3 смену изображений через эффект шторок - раздвигающихся панелей. Идея заключается в использовании фоновых изображений для панелей и их анимации при клике по <label>.

Разметка HTML

            <section class="cr-container">                
                <input id="select-img-1" name="radio-set-1" type="radio" class="cr-selector-img-1" checked/>
                <label for="select-img-1" class="cr-label-img-1">1</label>
               
                <input id="select-img-2" name="radio-set-1" type="radio" class="cr-selector-img-2" />
                <label for="select-img-2" class="cr-label-img-2">2</label>
               
                <input id="select-img-3" name="radio-set-1" type="radio" class="cr-selector-img-3" />
                <label for="select-img-3" class="cr-label-img-3">3</label>
               
                <input id="select-img-4" name="radio-set-1" type="radio" class="cr-selector-img-4" />
                <label for="select-img-4" class="cr-label-img-4">4</label>
               
                <div class="clr"></div>   
                <div class="cr-bgimg">
