用svg实现一个环形进度条

svg实现环形进度条需要用到的知识：

1、会使用path的d属性画一个圆环

//用svg的path元素的A命令画圆

<path
    d="
        M cx cy
        m 0 -r
        a r r 0 1 0 0 2r
        a r r 0 1 0 0 -2r"
>
></path>

//cx cy起点   r  半径

2、熟悉stroke,stroke-linecap,stroke-width,stroke-dasharray、stroke-dashoffset

话不多说，直接上代码

<div style="width: 200px;height: 200px;">
    <svg viewBox="0 0 100 100">
        <path
            d="M 50 50 m -40 0 a 40 40 0 1 0 80 0  a 40 40 0 1 0 -80 0"
            fill="none"
            stroke="#e5e9f2"
            stroke-width="5">
        ></path>
        <path
            d="M 50 50 m -40 0 a 40 40 0 1 0 80 0  a 40 40 0 1 0 -80 0"
            fill="none"
            stroke="#20a0ff"
            stroke-linecap="round"
            class="my-svg-path"
            transform="rotate(90,50,50)"
            stroke-width="5">
        </path>
    </svg>
</div>

.my-svg-path{
    stroke-dasharray: 252.2px, 252.2px;
    stroke-dashoffset: 22px;
    transition: stroke-dashoffset 0.6s ease 0s, stroke 0.6s ease 0s;
    transform: rotateZ(90deg);
    transform-origin: 50% 50%;
}

效果：
