使用方法：

1、head引入css文件

<!--圖標(biāo)樣式-->
<link rel='stylesheet' >

<!--主要樣式-->
<link rel="stylesheet" href="css/style.css">

2、body引入HTML代碼

<div class="main-container">
    <div class="steps-container">
        <div class="step completed">
            <svg xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24">
