完成详情页头部布局

详情页头部部分比较简单，和基金列表页类似。关键代码如下

<view class="header">
    <view class="fund-code">0005864</view>
    <view style="font-size:14px;color:#666;margin-top:20px;">金额(元)</view>
    <view class="balance">10000</view>
    <view class="header-info">
        <view>
            <view class="light-word">昨日收益(元)</view>
            <view class="money">+180</view>
        </view>
        <view style="border-left:solid 1px #eee;border-right:solid 1px #eee;">
            <view class="light-word">持有收益(元)</view>
            <view  class="money">+180</view>
        </view>
        <view>
            <view class="light-word">累计收益(元)</view>
            <view  class="money">+180</view>
        </view>
    </view>
</view>
