使用一些<svg>s 和<path>s 就可以了。

這是你的代碼：

.container {

  width: 500px;

  height: 100px;

  background-color: rgb(0, 224, 150);

  border: none;

  border-radius: 5px;

}

.text {

  width: inherit;

  position: absolute;

  top: 50px;

  text-align: center;

  font-family: 'Roboto', sans-serif;

  text-transform: uppercase;

  color: white;

  font-size: 24px;

}

<link href="https://fonts.googleapis.com/css2?family=Roboto:wght@900&display=swap" rel="stylesheet">

<div class="container">
