第 251 期 Shopify Before and After 图片对比模块以及条件控制设置项的使用方法演示

视频正在录制中，剪辑发布之后会更新链接在此

本期教程给大家分享一个适用于任何 Shopify 主题的图片 Before and After 对比功能，也就是用户可以拖动中间的滑块对比图片的前后效果。

同时这个模块中大量运用了 Shopify 前段时间新增的条件控制选项，可以在特定的选项开启时才展示某个或某些其他选项，这使得设置项面板更加简洁、直观。

• 在主设置项未开启时，大部分与其相关的设置项都自动隐藏：

用途和优势

引人注目的产品演示

• 清晰展示转变效果： 通过并排展示切实可见的效果，直观证明您的产品或服务的价值和功效
• 突出关键差异： 让客户能够立即理解您的产品所带来的改善或变化，使优势易于理解。
• 完美适用于视觉化产品： 对于以功能、功效带来变化为主要卖点的产品特别有效。
• 积极吸引用户参与： 滑块的互动性质鼓励用户直接与您的内容互动，查看 "After" 的状态。
• 简化复杂结果： 比冗长的描述或静态图像更有效地传达您产品的影响。

增强参与度和用户体验

• 立即吸引注意力： 动态和互动的滑块比静态内容更容易抓住并保持访客的注意力。
• 增加页面停留时间： 用户通常会花更多时间与滑块互动，这可以改善网站参与度指标。
• 提供难忘的互动体验： 提供独特且令人满意的用户体验，使您的产品页面脱颖而出。
• 改善信息记忆效果： 视觉对比通常比基于文本的声明更容易被记住，强化您产品的优势。
• 移动端友好互动： 实施良好的免费滑块通常具有响应式设计，在所有设备上提供流畅体验。

提升转化潜力和销售额

• 直接影响购买决策： 通过视觉化展示价值，滑块可以克服最后的犹豫并鼓励加购物车行为。
• 减少购买前疑问： 清晰的视觉证据可以主动回答许多客户关于产品功效的问题。
• 与竞争对手区别开来： 前后对比展示可以让您在那些没有有效展示效果的商店中获得优势。
• 支持营销宣传： 为您的广告和促销信息提供强有力的视觉支撑，增加其影响力。
• 零成本转化工具： 利用强大的视觉说服技巧来潜在地增加销售额，而不会增加您的运营费用
