Question

我正在使用Materialize.css框架，我注意到文本input字段的颜色是绿色，label也是。

有没有办法将颜色更改为不同的颜色？

<input type="text" id="username" />
<label for="username">Username</label>

Answer 1

根据Materialize Docs，你可以使用：

 /* label focus color */
   .input-field input[type=text]:focus + label {
     color: #000;
}
/* label underline focus color */
   .input-field input[type=text]:focus {
     border-bottom: 1px solid #000;
     box-shadow: 0 1px 0 0 #000;
   }

/*** !important was needed for snippet ***/



/* label focus color */
 .input-field input:focus + label {
   color: red !important;
 }
 /* label underline focus color */
 .row .input-field input:focus {
   border-bottom: 1px solid red !important;
   box-shadow: 0 1px 0 0 red !important
 }

        <i class="material-icons prefix">phone</i>
        <input id="icon_telephone" type="tel" class="validate">
        <label for="icon_telephone">Telephone</label>
      </div>
    </div>

dippas答案是正确的，但如果你想要textareas是相同的颜色，你必须设置这个CSS规则：

/* label focus color */
    .input-field input[type=text]:focus + label, .materialize-textarea:focus:not([readonly]) + label {
     color: #005eed !important;
    }

/* label underline focus color */
    .input-field input[type=text]:focus, .materialize-textarea:focus:not([readonly]) {
     border-bottom: 1px solid #005eed !important;
     box-shadow: 0 1px 0 0 #005eed !important;
    }

请注意标签和边框底部的.materialize-textarea规则。

在文档中说明如何设置materialize默认颜色。您需要将sass个文件下载到项目中，然后需要更改这些变量。

您需要转到/sass/components/forms/*/设置所需的元素。

在所有元素中，您可以看到颜色是$secondary-color，您可以在/sass/components/_variables.scss文件中找到该变量，并且您可以将其值设置为您所有项目的颜色。

Answer 4

最后，我找到了解决方案。您需要将颜色更改为活动和不活动。

图标：

.material-icons{
  color: #1a237e !important;
  }

.material-icons.active {
  color: #b71c1c !important;
  }

文本字段：

.input-field input[type=text] + label, .materialize-textarea:focus:not([readonly]) + label {
 color: #1a237e !important;
}

.input-field input[type=text], .materialize-textarea:focus:not([readonly]) {
 border-bottom: 1px solid #1a237e !important;
 box-shadow: 0 1px 0 0 #1a237e !important;
}


.input-field input[type=text]:focus + label, .materialize-textarea:focus:not([readonly]) + label {
 color: #b71c1c !important;
}

.input-field input[type=text]:focus, .materialize-textarea:focus:not([readonly]) {
 border-bottom: 1px solid #b71c1c !important;
 box-shadow: 0 1px 0 0 #b71c1c !important;
}

万一有人在2019年出现，并尝试使用新版本的Materialize（1.0.0）和不想使用 ！在他们的CSS中很重要 ，下面的代码段对我有用。

注意：这将适用于所有输入字段，如果需要特定的输入字段（即文本），则将[type]更改为[type = text]。

    /* Inactive/Active Default input field color */
    .input-field input[type]:not([readonly]),
    .input-field input[type]:focus:not([readonly]),
    .input-field textarea:not([readonly]),
    .input-field textarea:focus:not([readonly]) {
        border-bottom: 1px solid #01579b;
        box-shadow: 0 1px 0 0 #01579b;
    }

    /* Inactive/Active Default input label color */
    .input-field input[type]:focus:not([readonly])+label,
    .input-field textarea:focus:not([readonly])+label {
        color: #01579b;
    }

    /* Active/Inactive Invalid input field colors */
    .input-field input[type].invalid,
    .input-field input[type].invalid:focus,
    .input-field textarea.invalid,
    .input-field textarea.invalid:focus {
        border-bottom: 1px solid #e57373;
        box-shadow: 0 1px 0 0 #e57373;
    }

    /* Active/Inactive Invalid input label color */
    .input-field input[type].invalid:focus+label,
    .input-field input[type].invalid~.helper-text::after,
    .input-field input[type].invalid:focus~.helper-text::after, 
    .input-field textarea.invalid:focus+label,
    .input-field textarea.invalid~.helper-text::after,
    .input-field textarea.invalid:focus~.helper-text::after {
        color: #e57373;
    }

    /* Active/Inactive Valid input field color */
    .input-field input[type].valid,
    .input-field input[type].valid:focus,
    .input-field textarea.valid,
    .input-field textarea.valid:focus {
        border-bottom: 1px solid #26a69a;
        box-shadow: 0 1px 0 0 #26a69a;
    }

    /* Active/Inactive Valid input label color */
    .input-field input[type].valid:focus+label,
    .input-field input[type].valid~.helper-text::after,
    .input-field input[type].valid:focus~.helper-text::after,
    .input-field textarea.valid:focus+label,
    .input-field textarea.valid~.helper-text::after,
    .input-field textarea.valid:focus~.helper-text::after {
        color: #26a69a;
    }
