===弹性布局：组件的嵌套===
给组件添加了内容：

 <nowiki>
<view>
        <view>
            <image src=" /images/avatar/3.png"></image>
            <text>Nov 18 2020</text>
        </view>
        <text>2020LPL夏季赛季后赛观赛指南</text>
        <image src=" /images/lpl.png"></image>
        <text>8月9号，LPL常规赛收官之战结束，在事关</text>
        <view>
            <image src=" /images/icon/chat.png"></image>
            <text>92</text> 
            <image src=" /images/icon/view.png"></image>
            <text>102</text>
        </view>
    </view></nowiki>

===弹性布局：组件的修饰===
为组件添加了样式：

wxml:

 <nowiki>
<view class="post-container">
        <view class="post-author-date">
            <image class="post-author" src=" /images/avatar/3.png"></image>
            <text class="post-date">Nov 18 2020</text>
        </view>
        <text>2020LPL夏季赛季后赛观赛指南</text>
        <image src=" /images/lpl.png"></image>
        <text>8月9号，LPL常规赛收官之战结束，在事关</text>
        <view>
            <image src=" /images/icon/chat.png"></image>
            <text></text> 
            <image src=" /images/icon/view.png"></image>
            <text></text>
        </view>
    </view></nowiki>

wxss:

 <nowiki>
.post-container{
  display: flex;
  flex-direction: column;margin-top: 20rpx;
  margin-bottom: 40rpx;
  background-color:#fff;
  border-top: 1px solid#ededed;
  border-bottom: 1px solid#ededed;
  padding-bottom: 10rpx;
}
.post-author-date{
  /*margin-top : 10rpx;margin-bottom: 20rpx;margin-left: 10rpx;*/
  margin: 10rpx 0 20rpx 10rpx;
}
  .post-author{
    width:60rpx;height:60rpx;
    vertical-align: middle;
  }
  </nowiki>

===弹性布局：设置元素居中===
用Flex布局设置元素居中：

*display:flex;
*flex-direction: row;
*align-items:center;

 <nowiki>
.post-author-date{
  /*margin-top : 10rpx;margin-bottom: 20rpx;margin-left: 10rpx;*/
  margin: 10rpx 0 20rpx 10rpx;
  display:flex;
  flex-direction: row;
  align-items:center;
}
  .post-author{
    width:60rpx;height:60rpx;
    /* vertical-align: middle; */
  }
  .post-date{
    margin-left:20rpx;
    font-size:26rpx;
  }</nowiki>

===弹性布局：组件的修饰（二）===
修饰文章标题：

 <nowiki>
<text class="post-title">2020LPL夏季赛季后赛观赛指南</text></nowiki>

WXSS:

 <nowiki>
.post-title{
    font-size: 34rpx;font-weight: 600;
    margin-bottom: 20rpx; margin-left: 20rpx;
  }</nowiki>

修饰图片和文字：

 <nowiki>
        <image class="post-image" src=" /images/lpl.png"></image>
        <text class="post-content">8月9号，LPL常规赛收官之战结束，在事关</text></nowiki>

WXSS:

 <nowiki>
  .post-image{
    width: 100%;height: 340rpx;
    margin-bottom: 30rpx;
  }
  .post-content{
    color:#666;font-size: 28rpx;
    margin-bottom: 20rpx;
    margin-left:20rpx;
    line-height: 40rpx;letter-spacing: 2rpx;
  }</nowiki>

===弹性布局：组件的水平排列===

 <nowiki>
        <view class="post-like">
            <image  class="post-like-image" src=" /images/icon/chat.png"></image>
            <text class="post-like-font">02</text> 
            <image  class="post-like-image" src=" /images/icon/view.png"></image>
            <text class="post-like-font">100</text> 
        </view></nowiki>

wxss:

 <nowiki>
  .post-like{
    display: flex;
    flex-direction: row;
    align-items: center;
    margin-left: 20rpx;
  }
  .post-like-image{
    height : 32rpx;
    width: 32rpx;
    margin-right : 16rpx;
  }
 .post-like-font{
    margin-right: 40rpx;
    font-size: 26rpx;
  }
</nowiki>

====补充：png图片===
小程序图标不建议采用png图片，原因有二：

*不方便改大小
*不方便改颜色
