html - 输入内的按钮 (HTML/CSS)

Question

我希望我的按钮位于文本输入框内。像这样:

这是我的代码:

input {
        background: #8196aa;
        border: 0;
        border-radius: 10px;
        color: white;
        padding: 20px;

        &:focus {
            outline: none;
        }

        &::placeholder {
            color: white;
        }
    }

    button {
        background: #16bdae;
        border: 0;
        border-radius: 7px;
        color: white;
        padding: 15px;
    }

<div class="pt-site-footer__submit">
  <input type="email" placeholder="Your e-mailadress">
  <button>LOGIN</button>
</div>

我希望有人对此有答案。 (Stack Overflow 上的其他答案对我没有帮助)
