第一步

代码

<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>
</head>

<body>
    <div class="trangle"></div>
</body>

</html>

<style>
    * {
        margin: 0;
        padding: 0;
    }
    
    .trangle {
        margin: 0 auto;
        margin-top: 100px;
        width: 0;
        height: 0;
        border: 200px solid #909399;
        border-top-color: #409EFF;
        border-bottom-color: #67C23A;
        border-left-color: #E6A23C;
        border-right-color: #F56C6C;
    }
</style>

第二步

border-bottom: 0;
border-left-color: transparent;
border-right-color: transparent;

代码

<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>
</head>

<body>
    <div class="trangle"></div>
</body>

</html>

<style>
    * {
        margin: 0;
        padding: 0;
    }
    
    .trangle {
        margin: 0 auto;
        margin-top: 100px;
        width: 0;
        height: 0;
        border: 200px solid #909399;
        border-top-color: #409EFF;
        border-bottom-color: #67C23A;
        border-left-color: #E6A23C;
        border-right-color: #F56C6C;
        /* 根据需要调整方位 */
        border-bottom: 0;
        border-left-color: transparent;
        border-right-color: transparent;
    }
</style>

简化一下代码

<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>
</head>

<body>
    <div class="trangle"></div>
</body>

</html>

<style>
    * {
        margin: 0;
        padding: 0;
    }
    
    .trangle {
        margin: 0 auto;
        margin-top: 100px;
        width: 0;
        height: 0;
        border-bottom: 200px solid #67C23A;
        border-left: 200px solid transparent;
        border-right: 200px solid transparent;
    }
</style>

如果不要颜色的话

.trangle::after {
        content: "";
        z-index: 99;
        border-left: 197px solid transparent;
        border-right: 197px solid transparent;
        border-bottom: 197px solid white;
        position: absolute;
        top: 101px;
        left: 103px;
    }

        /* 与后面有关的代码 */
