按 angular material 主题设置文本输入颜色

Question

我对 angular material 主题化真的很陌生。实际上是大约 30 分钟前开始的！ :)

所以我可以设置主色、重音色和警告色。

现在我正在尝试在我的主题中设置文本输入颜色。

不知道如何正确地做到这一点...

我检查了 mat-input 元素并注意到 placeholder 标签的颜色由以下类设置： mat-form-field-appearance-legacy 和 mat-form-field-label.

我创建了以下主题文件：

@import '~@angular/material/theming';
// Plus imports for other components in your app.

// Include the common styles for Angular Material. We include this here so that you only
// have to load a single css file for Angular Material in your app.
// Be sure that you only ever include this mixin once!
@include mat-core();

// Define the palettes for your theme using the Material Design palettes available in palette.scss
// (imported above). For each palette, you can optionally specify a default, lighter, and darker
// hue. Available color palettes: https://material.io/design/color/
$candy-app-primary: mat-palette($mat-indigo);
$candy-app-accent:  mat-palette($mat-pink, A200, A100, A400);

// The warn palette is optional (defaults to red).
$candy-app-warn:    mat-palette($mat-amber);

// Create the theme object (a Sass map containing all of the palettes).
$candy-app-theme: mat-light-theme($candy-app-primary, $candy-app-accent, $candy-app-warn);

// Include theme styles for core and each component used in your app.
// Alternatively, you can import and @include the theme mixins for each component
// that you are using.

.mat-form-field-appearance-legacy .mat-form-field-label {
  color: white;
}
@include angular-material-theme($candy-app-theme);

这根本不会影响 mat-input 占位符颜色。

所以我想了解如何使用主题正确设置输入颜色。

如有任何关于此问题的想法，我们将不胜感激。

考虑在开始之前查看 Customizing Component Styles 指南。

无论如何，您必须使用 !important 样式，因为您的样式将被 Angular Material 的样式覆盖：

// ...
.mat-form-field-appearance-legacy .mat-form-field-label {
  color: white !important;
}
