Solving the problem of mini program canvas hiding

I believe that many times, everyone will encounter the need to use canvas to generate pictures.
Of course I also encountered it. After generating the canvas in the wxml page of the project, I found out how to add css to the canvas tag. I can't prevent the canvas from affecting the page.

  <canvas>
    // 无论是opacity  还是  z-index 都无法解决,多多少少会影响
   </canvas>

After thinking about it for a while, I came up with the following solution: Add a parent tag to the outer layer of canvas, and then Control the display of the parent tag

<view> //让父标签 0宽 0高 隐藏溢出
    <canvas>
    </canvas>
</view>

If the above does not work, please see the following:

  <canvas>
// 直接让canvas 飞到天际,  简单粗暴;   使用时注意 position的问题; 如果 fixed不行, 换其他定位试试
    </canvas>

ok .. Come on and write the code...
