微信小程序背景渐变图片

卡片可能适合很多场景，但是单纯的色彩背景略显单调。如果想要不单调，可以使用图片作为背景，达到很少元素也不再单调的效果。

如上图的效果，代码如下：

/**
 * wxml
 */

<view class="card" wx:for="{{humanCard}}" wx:key="this">
    <!-- 主要内容 -->
    <view class="main-content">
	<view class="human-info">
	    <image mode="aspectFill" src="{{item.avatar}}"></image>
	    <view>
	        <text>{{item.name}}</text>
	        <text>{{item.position}}</text>
            </view>
	</view>
	<view class="human-intro"><text decode>{{item.intro}}</text></view>
    </view>
    <!-- 人物图片 -->
    <view class="human-image">
        <view class="bg" style="background: linear-gradient(55deg,rgb(255, 255, 255) 30%, rgba(0,0,0,0)),url({{item.imageUrl}}) no-repeat right/cover;"></view>
    </view>
</view>
