如何覆盖angular 2材质样式? [英] How to overwrite angular 2 material styles?

问题描述

我在角材料中有这个选择:

I have this select in angular material:

它的代码:

<md-select placeholder="Descuentos y convenios" [(ngModel)]="passenger.discount">
        <md-option [value]="null" [disabled]="true">
            Descuentos
        </md-option>
        <md-option *ngFor="let option of discounts" [value]="option">
            {{ option }}
        </md-option>
        <md-option [value]="null" [disabled]="true">
            Convenios
        </md-option>
        <md-option *ngFor="let option of agreements" [value]="option">
            {{ option }}
        </md-option>
</md-select>

而且我想在其中包含这种样式:

And I would like to have this styles in it:

我试图将一些类放在 md-select 和 md-option 上，但没有奏效.我想提供一个如何放置背景颜色或边框的示例，这会给我一个想法.

I tried to put some classes over md-select and md-option, but not worked. I would like to have maybe just an example of how to put the background color or the border and that would give me an idea.

先谢谢你

推荐答案

我认为类应该有效，但您可能需要使用 /deep/ 因为视图封装.

I think classes should work, but you may need to use /deep/ because of the view encapsulation.

试试这个:

/deep/ md-select.your-class {
  background-color: blue;
}

您还可以玩主题.
