今天学习了：页面的渐变背景、使用deep修改子组件样式、全屏页面absolute定位布局和fit-content内容宽度、遮罩层状态转换及日期格式化、uni-popup弹窗层制作弹出信息
页面的渐变背景
需要设置页面背景，使用的是多个页面，这样就可以把背景做成组件，只用在需要的地方调用，例如：，这里是某一页面的最外层的盒子，这里是给盒子定义了一个名称，然后在添加了自定义的样式pageBg，在文件夹common下的scss文件，
html
.pageBg{
background:
linear-gradient(to bottom,transparent,#fff 400rpx),
linear-gradient(to right,#beecd8 20%,#F4E2D8);
min-height: 80vh;
}这就实现了页面的渐变。说真的，小白不清楚为什么，只是知道怎么用，这里老师有文档详细解释，只是自己看的云里雾里的，
css渐变背景，linear-gradient()线性渐变和radial-gradient()径向渐变
deep的使用
html
:deep(){
.uni-icons{
color: $brand-theme-color !important;
}
}这是使用deep修改子组件的样式，里面有关键字 !important，这里并不是很清楚，只能是在网上查看，看是什么意思，
deep的使用
absolute定位布局和fit-content内容宽度
这是在当全局都有使用的时候，可以把相同的这部分样式放在外部，这样子组件就不用在写这个了，
html
&>view {
position: absolute;
left: 0;
margin: auto;
right: 0;
color: #fff;
width: fit-content; //fit-content代表内容多大自定义宽度
}这就是放在外部，其他子组件就不用写了，这里是用的&>view
遮罩层状态转换及日期格式化
这里是在页面上添加浮框，
就是做成这种效果，这里不做过多说明，直接上代码
html
.mask {
&>view {
position: absolute;
left: 0;
margin: auto;
right: 0;
color: #fff;
width: fit-content; //fit-content代表内容多大自定义宽度
}
.goBack {}
.count {
top: 10vh;
background: rgba(0, 0, 0, 0.3);
font-size: 28rpx;
border-radius: 40rpx;
padding: 8rpx 28rpx;
backdrop-filter: blur(10rpx);
}
.time {
font-size: 140rpx;
top: calc(10vh + 80rpx);
font-weight: 100;
line-height: lem;
text-shadow: 0 4rpx rgba(0, 0, 0, 0.3);
}
.data {
font-size: 34rpx;
top: calc(10vh + 230rpx);
text-shadow: 0 2rpx rgba(0, 0, 0, 0.3);
}
.footer {
background: rgba(255, 255, 255, 0.8);
bottom: 10vh;
width: 65vw;
height: 120rpx;
border-radius: 120rpx;
color: #000;
display: flex;
justify-content: space-around;
align-items: center;
box-shadow: 0 2rpx 0 rgba(0, 0, 0, 0.1);
backdrop-filter: blur(20rpx);
.box {
display: flex;
flex-direction: column;
align-items: center;
justify-content: center;
padding: 2rpx 12rpx;
.text {
font-size: 26rpx;
color: $text-font-color-2;
}
}
}
}这里主要是样式的使用，下面是页面的布局
html
<view class="mask" v-if="maskState">
<view class="goBack">
</view>
<view class="count">
3/9
</view>
<view class="time">
<uni-dateformat :date="Date.now()" format="hh:mm"></uni-dateformat>
</view>
<view class="data">
<uni-dateformat :date="Date.now()" format="MM月dd日"></uni-dateformat>
</view>
<view class="footer">
<view class="box" @click="clickInfo">
<uni-icons type="info" size="28"></uni-icons>
<text class="text">信息</text>
</view>
<view class="box" @click="clickScore">
<uni-icons type="star" size="28"></uni-icons>
<text class="text">5分</text>
</view>
<view class="box">
<uni-icons type="download" size="23"></uni-icons>
<text class="text">下载</text>
</view>
</view>
</view>uni-popup弹窗层制作弹出信息
这是最复杂的，目前只是跟着视频做出来的，但是没有达到自己弄来
这是效果图，也是当期这个也买最复杂的布局和样式，这里就把全部代码放着，自己目前也是不怎么清楚
html
<template>
<view class="preview">
