商品购物添加购物车界面设计

PetitQ 图片/图形 2019-1-22 2.55K 0 0

这是一款简单实用的商品购物和添加购物车界面设计方案。用户可以在商品购物界面中预览各种型号、颜色、尺寸的商品。然后通过点击添加到购物车按钮就可以将该商品添加到购物车中，操作简单直观。在传统的购物网站中，用户在商品展示界面看中了一件商品之后，点击这件商品的缩略图，然后可以键入到对应水平的子页面中。在这个子页面中，用户可以选择查看一些商品的属性，然后把商品添加到购物车中。但是在这个购物车界面设计中，用户可以直接在购物界面查看商品的属性，并直接将商品添加到购物车中，简化了用户的操作，大大提升了用户的体验度。通过在商品预览图界面添加“快速添加到购物车”按钮，可以减少用户的操作步骤，提升用户体验，增加转化率。

HTML 结构

该购物界面的 HTML 结构使用一个无序列表来制作。每一个无序列表项中又包含一个无序列表，由于制作商品的图片画廊。div.cd-customization 是包含商品的属性和“添加到购物车”按钮的面板。div.cd-item-info 是商品的名称和价格。

CSS 样式

对于商品的图片画廊，默认情况下，列表项使用绝对定位，并被移动到它的父元素.cd-gallery 之外，因此它们是不可见的。它们使用了两个 class：.selected 用于添加到列表项的第一项，使其可见，.move-left，图片向左移动，使其不可见。

```
.cd-slider-wrapper {
```
```
  position: relative;
```
```
  overflow: hidden;
```
```
}
```
```
.cd-slider-wrapper li {
```
```
  position: absolute;
```
```
  top: 0;
```
```
  left: 0;
```
```
  visibility: hidden;
```

  /* by default, move the product image to the right*/

```
  transform: translateX(100%);
```

  transition: transform 0.3s 0s, visibility 0s 0.3s;

```
}
```
```
.cd-slider-wrapper li.selected {
```

  /* this is the visible product image */

```
  position: relative;
```
```
  visibility: visible;
```
```
  z-index: 1;
```
```
  transform: translateX(0);
```

  transition: transform 0.3s 0s, visibility 0s 0s;

```
}
```
```
.cd-slider-wrapper li.move-left {
```

  /* move the product image to the left */

```
  transform: translateX(-100%);
```
```
}
```

.cd-customization 元素在用户用鼠标滑过商品缩略图时才被显示出来。它使用绝对定位并放置在父元素.cd-single-item 的下面。为了创建自定义选项（商品的颜色和尺寸），这里使用了不同的<ul>元素，它们都被包裹在 div[data-type="select"]元素中。<ul>元素使用绝对定位，并相对于他们的父元素居中。它们的父元素 div[data-type="select"]有固定的高度（34px）以及 overflow:hidden 属性。无序列表中的每一个列表项的高度都和 div[data-type="select"]相同，因此默认情况下，只有被选择的项是可见的。当用户点击了某个自定义选项时，div[data-type="select"]的 overflow 属性被设置为可见，这样整个<ul>元素都被显示出来。

```
.cd-customization {
```
```
  position: absolute;
```
```
  left: 0;
```
```
  bottom: 0;
```
```
  width: 100%;
```
```
  visibility: hidden;
```
```
  opacity: 0;
```
```
}
```
```
 
```

.no-touch .cd-single-item:hover .cd-customization {

```
  /* product customization visible */
```
```
  pointer-events: auto;
```
```
  visibility: visible;
```
```
  opacity: 1;
```
```
}
```
```
 
```

.cd-customization .color, .cd-customization .size {

```
  height: 34px;
```
```
  position: relative;
```
```
  overflow: hidden;
```
```
}
```

.cd-customization .color ul, .cd-customization .size ul {

```
  display: inline-block;
```
```
  position: absolute;
```
```
  left: 50%;
```
```
  top: 50%;
```

  transform: translateX(-50%) translateY(-50%);

```
  width: 100%;
```
```
}
```

.cd-customization .color.is-open, .cd-customization .size.is-open {

  /* color/size list open - make ul element visible */

```
  overflow: visible;
```
```
}
```

为了确保被选择的<li>元素一直可见，插件中通过创建.selected-n class 对<ul>元素中的列表项进行了重新排列。例如：当第 3 个列表项被选择的时候，.selected-3 会被添加到 div[data-type="select"]中。

.cd-customization .color.selected-3 ul li:first-of-type,

.cd-customization .size.selected-3 ul li:first-of-type {

  /* third option selected in the ul.color/ul.size list */

```
  transform: translateY(0);
```
```
}
```

.cd-customization .color.selected-3 ul li:nth-of-type(2),

.cd-customization .size.selected-3 ul li:nth-of-type(2) {

```
  transform: translateY(100%);
```
```
}
```

.cd-customization .color.selected-3 ul li:nth-of-type(3),

.cd-customization .size.selected-3 ul li:nth-of-type(3) {

```
  transform: translateY(-100%);
```
```
}
```

“添加到购物车”按钮.add-to-cart 由一个<em>元素（按钮上的文本）和一个 SVG（check 图标）组成。默认情况下，图标是不可见的。当商品被添加到购物车的时候，.add-to-cart 按钮被添加了.is-added class：此时<em>元素被隐藏（移动到左边），SVG 图标被移动回中间，然后开始绘制动画。

```
.cd-customization .add-to-cart em {
```
```
  /* this is the button text message */
```
```
  position: absolute;
```
```
  top: 0;
```
```
  left: 0;
```
```
  width: 100%;
```
```
  height: 100%;
```
```
}
```
```
.cd-customization .add-to-cart svg {
```
```
  /* this is the check icon */
```
```
  position: absolute;
```
```
  left: 50%;
```
```
  top: 50%;
```
```
  width: 100%;
```

  /* move the icon on the right - outside the button */

  transform: translateX(50%) translateY(-50%);

```
}
```

.cd-customization .add-to-cart.is-added em {

  /* product added to the cart - hide text message on the left with no transition*/

```
  color: transparent;
```
```
  transform: translateX(-100%);
```
```
}
```

.cd-customization .add-to-cart.is-added svg {

  /* product added to the cart - move the svg back inside the button */

  transform: translateX(-50%) translateY(-50%);

```
}
```

SVG 图标的绘制动画使用的是 stroke-dasharray 和 stroke-dashoffset 属性。如果你对 SVG 感兴趣，可以点击这里查看关于 SVG 教程。
