＆＃13; 为什么中间圆圈（黄色）从底部向上升起。？它是如何变化的？

Answer 1

因为中间圆的起点被翻转。

最简单的解决方法是将stroke-dasshoffset属性添加到中间圆圈以移动笔划的起点，就像这样。

<path id="innerRing" fill="none" stroke="#F7DE4B" 
stroke-dashoffset="168.409" 
stroke-width="10" stroke-miterlimit="10" 
d="M227.1,25.8c-43.4,0-78.6,8.6-78.6,19.4s35.2,19.4,78.6,19.4s78.6-8.6,78.6-19.4
    S270.6,25.8,227.1,25.8z"/>
