在Materialize.css框架中更改下划线输入和标签的颜色

Question

我正在使用Materialize.css框架，我注意到input字段的文本颜色是绿色的，而且label也是绿色的。

有没有办法将颜色更改为其他颜色？

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

Answer 1

根据Materialize Docs，您可以使用以下方法：

 /* 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
 }

Material Css（http://materializecss.com/forms.html）没有提到使用`!important`；他们错了吗？ - user31782

Answer 2

dippas的回答是正确的，但如果您想让文本区域具有相同的颜色，则必须设置以下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;
    }

请注意使用 .materialize-textarea 规则来设置标签和底部边框。

如果有人在2019年并尝试使用最新版本的Materialize（1.0.0）同时不想在他们的CSS中使用！important，则下面的代码片段适用于我。

注意：这将应用于所有输入字段，如果您想要特定的输入字段，例如文本，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;
    }

最终，我找到了解决方案。您需要更改活动和非活动状态的颜色。

图标：

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

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

文本框：

.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;
}

在文档中介绍了如何设置Materialize的默认颜色。您需要将sass文件下载到您的项目中，然后需要更改这些变量。您需要进入/sass/components/forms/*/来设置所需的元素。

在所有元素中，您可以看到颜色是$secondary-color，该变量可以在/sass/components/_variables.scss文件中找到，并且您可以将其值更改为您的颜色以用于整个项目。
