How can I change mat-icon-button size? My icon has 24px now and I would like to increase that value to 48px. I use mat-icon as a button content. I also noticed that mat-icon-button has just hardcoded 40px/40px size.

<button mat-icon-button color="primary">
    <mat-icon class="material-icons">play_circle_filled</mat-icon>
</button>

推荐答案

使用两个选项之一覆盖mat-icon的字体大小. (我将md-更改为mat-以获取最新的AM版本)

Override the font size of mat-icon using either of the options. (I changed md- to mat- for the newest AM version)

::ng-deep可以深入到主机中的该类.宽度和高度也应设置为按比例调整背景大小.

---

::ng-deep to reach that class deep in the host. The width and the height should be also set to adjust the backdrop size proportionally.

HTML:

<button mat-button>    
  <mat-icon class="material-icons">play_circle_filled</mat-icon>
</button>

CSS

::ng-deep .mat-icon{
    height:48px !important;
    width:48px !important;
    font-size:48px !important;
}

或者，如果您避免使用::ng-deep，请使用ViewEncapsulation.None(但要谨慎使用):

---

Or, if you avoid ::ng-deep, use ViewEncapsulation.None (but use sparingly):

班级:

import {ViewEncapsulation} from '@angular/core';

@Component({
  encapsulation: ViewEncapsulation.None
})

然后，您可以直接从组件样式表中进行样式设置.

Then you can style directly from the component stylesheet.

CSS:

.mat-icon{
    height:48px !important;
    width:48px !important;
    font-size:48px !important;
}

或从主样式表styles.css中对其进行样式设置:

---

Or style it from the main stylesheet, styles.css:

styles.css

.mat-icon{
    height:48px !important;
    width:48px !important;
    font-size:48px !important;
}

最后但并非最不重要的解决方案，可以内联进行样式:

---

And last, but not the least solution, styling can be done inline:

HTML:

<button mat-button>    
  <mat-icon style="
    height:48px !important;
    width:48px !important;
    font-size:48px !important;" class="material-icons">play_circle_filled</mat-icon>
</button>
