如何添加对齐表单输入字段并在它们之间添加空格？

<style>
    .form-group {
        display: block;
        margin-bottom: 10px;
    }

    .form-group input {
        width: 200px;
    }
</style>

<form>
    <div class="form-group">
        <label for="name">姓名：</label>
        <input type="text" id="name">
    </div>

    <div class="form-group">
        <label for="email">邮箱：</label>
        <input type="email" id="email">
    </div>

    <div class="form-group">
        <label for="password">密码：</label>
        <input type="password" id="password">
    </div>
</form>
