如何为angular material创建“自定义”自己的颜色?
例如像success
(绿色),warn
(黄色),danger
(红色),primary
(蓝色)旁边的{{1>颜色等引导程序(粉红色)。
换句话说:扩展Angular Material(2+)的颜色变量,以便在html属性中使用它:
accent
或创建一个白色的复选框,如:
<button mat-raised-button color="success">Success</button>

变量在&#34; _theming.scss&#34;中定义。它位于&#34; node_modules / @ angular / material /&#34;。定义我们需要修改以下函数的自定义变量。
Throwable
在同一个文件中,我们也可以应用新引入的变量 当我将它应用于按钮时到组件。
// Creates a container object for a light theme to be given to individual component theme mixins.
@function mat-light-theme($success, $primary, $accent, $warn: mat-palette($mat-red)) {
@return (
success:$success,
primary: $primary,
accent: $accent,
warn: $warn,
is-dark: false,
foreground: $mat-light-theme-foreground,
background: $mat-light-theme-background,
);
}
// Creates a container object for a dark theme to be given to individual component theme mixins.
@function mat-dark-theme($success, $primary, $accent, $warn: mat-palette($mat-red)) {
@return (
success:$success,
primary: $primary,
accent: $accent,
warn: $warn,
is-dark: true,
foreground: $mat-dark-theme-foreground,
background: $mat-dark-theme-background,
);
}
新的自定义变量可以添加到&#34; theme.scss&#34;文件
// Applies a focus style to an md-button element for each of the supported palettes.
@mixin _mat-button-focus-color($theme) {
$success: map-get($theme, success);
$primary: map-get($theme, primary);
$accent: map-get($theme, accent);
$warn: map-get($theme, warn);
&.mat-success .mat-button-focus-overlay {
background-color: mat-color($success, 0.12);
}
&.mat-primary .mat-button-focus-overlay {
background-color: mat-color($primary, 0.12);
}
&.mat-accent .mat-button-focus-overlay {
background-color: mat-color($accent, 0.12);
}
&.mat-warn .mat-button-focus-overlay {
background-color: mat-color($warn, 0.12);
}
&[disabled] .mat-button-focus-overlay {
background-color: transparent;
}
}
@mixin _mat-button-ripple-color($theme, $hue, $opacity: 0.2) {
$success: map-get($theme, success);
$primary: map-get($theme, primary);
$accent: map-get($theme, accent);
$warn: map-get($theme, warn);
&.mat-success .mat-ripple-element {
background-color: mat-color($success, $hue, $opacity);
}
&.mat-primary .mat-ripple-element {
background-color: mat-color($primary, $hue, $opacity);
}
&.mat-accent .mat-ripple-element {
background-color: mat-color($accent, $hue, $opacity);
}
&.mat-warn .mat-ripple-element {
background-color: mat-color($warn, $hue, $opacity);
}
}
// Applies a property to an md-button element for each of the supported palettes.
@mixin _mat-button-theme-color($theme, $property, $color: 'default') {
$success: map-get($theme, success);
$primary: map-get($theme, primary);
$accent: map-get($theme, accent);
$warn: map-get($theme, warn);
$background: map-get($theme, background);
$foreground: map-get($theme, foreground);
&.mat-success {
#{$property}: mat-color($success, $color);
}
&.mat-primary {
#{$property}: mat-color($primary, $color);
}
&.mat-accent {
#{$property}: mat-color($accent, $color);
}
&.mat-warn {
#{$property}: mat-color($warn, $color);
}
&.mat-success ,&.mat-primary, &.mat-accent, &.mat-warn, &[disabled] {
&[disabled] {
$palette: if($property == 'color', $foreground, $background);
#{$property}: mat-color($palette, disabled-button);
}
}
}
@mixin mat-button-theme($theme) {
$success: map-get($theme, success);
$primary: map-get($theme, primary);
$accent: map-get($theme, accent);
$warn: map-get($theme, warn);
$background: map-get($theme, background);
$foreground: map-get($theme, foreground);
.mat-button, .mat-icon-button {
background: transparent;
@include _mat-button-focus-color($theme);
@include _mat-button-theme-color($theme, 'color');
}
现在我们可以在html中使用新变量:
@import '~@angular/material/_theming';
@include mat-core();
$primary: mat-palette($mat-green);
$accent: mat-palette($mat-blue);
$warn: mat-palette($mat-blue);
$success: mat-palette($mat-blue);
$theme: mat-light-theme($success,$primary, $accent,$warn);
@include angular-material-theme($theme);
.dark-theme {
$dark-success: mat-palette($mat-light-blue);
$dark-primary: mat-palette($mat-light-blue);
$dark-accent: mat-palette($mat-green);
$dark-theme: mat-dark-theme($dark-success, $dark-primary, $dark-accent);
@include angular-material-theme($dark-theme);
}

你做不到。但是,如果您愿意,可以在某些元素上添加“ color =“ whatever”属性,这会为您添加自定义类。
示例:
.whatever {
background-color: light-blue;
}
<button mat-button color="whatever"></button> // this button will have '.mat-whatever' class.

在您的主要styles.css文件中添加以下样式
.mat-success {
color: #fff !important;
background-color: #28a745 !important;
}
.mat-success[disabled] {
background-color: rgba(0, 0, 0, 0.12) !important;
}
在组件中指定颜色名称
<button mat-raised-button color="success">

我在 PROJECT_NAME \ node_modules \ @angular \ material_theming.scss 中的文件 _theming.scss 中的相应调色板中添加了新颜色,这对我来说是成功的,并且成功通过了 ng构建--prod
您必须尊重颜色和字体之间的对比度,在我的情况下,颜色为#590F46,并且与白色字体具有良好的对比度。
执行此操作
示例 Code example just palette mat-pink in _theming.scss 和 My file with custom themes for angular material2 对不起,我的英语我只是想帮助:)
