This Blueprint is a responsive Isotope-powered product grid layout where each grid item is a Flickity image slider. A small cart icon animation indicates that a product was added to the shopping cart. The product filter utilizes the Isotope filter functionality. Some example media queries are used to show how to make the layout adaptive.
这个是一个敏感的同位素动力产品网格布局,每个网格项目是一个flickity图像滑块,一个小型车图标动画表明一个产品被添加到购物车,产品过滤器利用同位素过滤器功能,可以点击下面查看演示。
