好看的产品对比布局-Product Comparison Layout & Effect

好看的产品对比布局-Product Comparison Layout & Effect
This Blueprint is a responsive product grid layout with comparison functionality. A maximum of three items can be selected for the product comparison. The comparison view shows flexbox-powered columns or rows (depending on the viewport size) that appear with a slide-in effect. There are a couple of example media queries for smaller viewports.
此布局是具有比较多功能的响应式产品网格布局,最多可选择三个项目进行产品比较,(根据视口大小)出现在效果的幻灯片。
