使用：not（）选择器和属性选择器，可以排除 type = submit 。

Using the :not() selector with the attribute selector, you can exclude type="submit" from your rule.

input:not([type="submit"]) {
  color: red;
}

<input type="text" name="firstname" value="First Name" title="Type your First Name" onfocus="this.value='';">
<input type="text" name="lastname" value="Last Name" title="Type your Last Name">
<input type="email" name="email" value="user@email.com" title="Type your email">
<input type="tel" name="phone" pattern="^\(?:\(\d{2}\)|\d{2})[\d{1}][. ]?\d{4}[- ]?\d{4}" value="(xx)x.xxxx-xxxx" title="Type your phone number">
<input type="age" pattern=".{2,3}" name="idade" value="Age" title="Idade">
<input type="submit" value="Submit">
