问:实现CSS格式化形式输入

Question

我正在尝试更改物质CSS中表单输入的边框和标记颜色。我遵循文档，但仅更改了.input-fielddiv的第一个实例，其余的仍在使用默认样式。

codepen

html

<div class="input-field">
  <input id="account_name" type="text" class="validate">
  <label for="account_name">Account Name</label>
</div>
<div class="input-field">
  <input id="email" type="email" class="validate">
  <label for="email">Email</label>
</div>
<div class="input-field">
  <input id="password" type="password" class="validate">
  <label for="password">Password</label>
</div>

CSS

/* label color */
.input-field label {
    color: #000;
}
/* label focus color */
.input-field input[type=text]:focus + label {
    color: purple !important;
}
/* label underline focus color */
.input-field input[type=text]:focus {
    border-bottom: 1px solid purple !important;
    box-shadow: 0 1px 0 0 purple !important;
}
/* valid color */
.input-field input[type=text].valid {
    border-bottom: 1px solid purple !important;
    box-shadow: 0 1px 0 0 purple !important;
}
/* invalid color */
.input-field input[type=text].invalid {
    border-bottom: 1px solid #000;
    box-shadow: 0 1px 0 0 #000;
}
/* icon prefix focus color */
.input-field .prefix.active {
    color: #000;
}

您的CSS使用[type=text]伪选择输入。您不想也要用type="email"和type="password"获得那些吗？
