用于视频背景的Visual Composer视差

时间：2016-06-30 08:36:27

标签： javascript php wordpress html5-video visual-composer

我已经试图找到合适的解决方案。我在我的Visual Composer中添加了新行，现在我只想为它添加一个视差效果。

视差效果CSS是：

{background-position: center!important;
    background-repeat: no-repeat!important;
    background-attachment: fixed!important;
    background-size: cover!important;}

（Here is an example。）

我正在尝试编辑此部分

<div class="video-wrap">
                                           <div id="video-wrap">
                                        <video "id"="my-video" "class="video" width="1920" height="800" poster="'.$v_image.'" preload="metadata" loop autoplay muted>';
                                                if(!empty($video_webm)) { $output .= '


                                                <source type="video/webm" src="'.$video_webm.'">'; }
                                                if(!empty($video_mp4)) { $output .= '<source type="video/mp4" src="'.$video_mp4.'">'; }
                                                if(!empty($video_ogv)) { $output .= '<source type="video/ogg" src="'. $video_ogv.'">'; }
                                             $output .='<object width="320" height="240" type="application/x-shockwave-flash" data="'.get_template_directory_uri().'/js/flashmediaelement.swf">
                                                        <param name="movie" value="'.get_template_directory_uri().'/js/flashmediaelement.swf" />
                                                        <param name="flashvars" value="controls=true&file='.$video_mp4.'" />
                                                        <img src="'.$v_image.'" width="1920" height="800" title="No video playback capabilities" alt="Video thumb" />
                                                </object>
                                        </video>
                                        </div>
                                </div>
                                </section>';
