使用CSS在角度材质2元素内按ID或Class定位特定元素样式

问题描述

我有一个具有物料按钮菜单的EntryComponent.当我尝试使用:: ng-deep覆盖默认样式时，父组件中所有按钮组件的样式也会更改.

I am having an EntryComponent that has a material button menu. When I try to override the default style by using ::ng-deep the styling changes for all the button component in the parent Component as well.

 <style>
 ::ng-deep .mat-button{
  max-width: 50px !important;
  min-width: 45px !important;
  height: 5em;
 }
 ::ng-deep .mat-button-ripple mat-ripple{
  max-width: 40px !important;
  min-width: 20px !important;
 }
 </style>

我也尝试使用类来定位样式，但是我想它不能像普通的CSS一样工作.

I also tried to target styling using a class but it doesn't work like usual CSS I guess.

 <style>
 .actions ::ng-deep .mat-button{
  max-width: 50px !important;
  min-width: 45px !important;
  height: 5em;
 }

 .actions ::ng-deep .mat-button-ripple mat-ripple{
  max-width: 40px !important;
  min-width: 20px !important;
 }
 </style>

入口组件

<button md-button [mdMenuTriggerFor]="menu" class="actions">
<md-icon>flash_on</md-icon></button>
<md-menu #menu="mdMenu">

  <button md-menu-item>
    <md-icon>autorenew</md-icon>
  </button>

  <button md-menu-item>
   <md-icon>border_color</md-icon>
  </button>

  <button md-menu-item>
   <md-icon>delete</md-icon>
  </button>

  <button md-menu-item>
   <md-icon>perm_identity</md-icon>
  </button>

  <button md-menu-item>
   <md-icon>payment</md-icon>
  </button>
</md-menu>

PS:如上所述，这不是重复的问题，因为我们能够全局设置材料元素的样式，但问题是如何通过Id或Class设置目标dom元素的样式.希望这能消除混乱

PS: this is not a duplicate issue as mentioned as we are able to style material elements globally but the question was how to style a targeted dom element by means of Id or Class. Hope this clears the confusion

推荐答案

Milad已经回答了，只需要使用这种样式即可.

As already answered by Milad just needed to use this styling

<style>
:host /deep/ .actions{
  max-width: 50px !important;
  min-width: 45px !important;
  height: 5em;
}

:host /deep/ .actions .mat-button-ripple mat-ripple{
  max-width: 40px !important;
  min-width: 20px !important;
}
</style>
