How to overwrite angular 2 material styles?

I have this select in angular material:

Its code :

<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>

And I would like to have this styles in it:

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.

Thank you in advance

Me also faced this kind of situation, but I found a permanent solution to over come this.

If we use ::ng-deep or :root/CLASS_NAME or ViewEncapsulation it may affect other components also. So what you can do is,

Make sure your global style sheet is present at the end of styles array in your angular.json file

"styles": [
      "@angular/material/prebuilt-themes/indigo-pink.css",
      "src/styles.css"     <-----------
    ],

Inspect your code and get the relevant class from the browser
Get the relevant class and override it in your global style file (styles.css)

 .mdc-dialog__surface{
    background-color: antiquewhite !important;
    box-shadow:none !important;
  }
  
  .cdk-overlay-backdrop.cdk-overlay-backdrop-showing {
    opacity: 0.5;
  }

Updated style output

Similarly you can modify other Angular material components and Bootstrap inbuilt styles also.

you can use :root as well

:root {
    .mat-dialog-container{
        padding: 0px 
    }
}

I was facing the same issue with Angular Material, I inspected the select element, checked its classes and tried to overwrite the css rules for material css classes , even tried !important flag for style rules. But it was not working.

Moving all such rules from component to index.html worked for me.

.mat-select-value,
    .mat-option-text,
    .mat-standard-chip,
    .mat-input-element,
    .mat-menu-item {
         color: #666 !important;
         font-size: 13px !important;
     }
}

Anyone looking for a cleaner approach in 2020, use the panelClass as suggested in the material mat-select documentation. Use the panelClass property

I do it this way whenever I have to remove scroll from mat-sidenav-container

   .mat-sidenav-container-classname ::ng-deep mat-sidenav-content {
      overflow: hidden;
    }

The top solutions of /deep/, >>> and ::ng-deep are being deprecated and should no longer be used.

Edit: Word of warning. I do not recommend using this method at all (as of Jan 2019) as setting ViewEncapsulation.None will result in any of that components css becoming global styles (it stops Angular from creating ng_xxx attributes for component scoped css). This will result in global style conflict, especially with lazy loaded module css.

Our solution to ViewEncapsulation was to override very specific css using highly specific css selectors in 1) global css or 2) creating separate style files for certain views / styles / elements, importing into every component required (e.g. styleUrls: [material-table-override.css, component.css]).

I used ViewEncapsulation.None to successfully override material table styles within a single component in Angular 6.

On your component:

import { ViewEncapsulation } from '@angular/core';
// ...
@Component({
    // ...
    encapsulation: ViewEncapsulation.None,
})

Here's a great article on the subject

You can try adding this code.

.mat-dialog-container{
     padding: 0px !important;
}

If this does not work you can use

/deep/.className {
... your code goes here
}

The correct way to change styles of overlay classes like mat-dialog-container is to use panelClass according to Customizing Angular Material component styles:

Add this to your global stylesheet after your theme setup

.myapp-no-padding-dialog .mat-dialog-container {
  padding: 0;
}

Use the following to open the dialog

this.dialog.open(MyDialogComponent, {panelClass: 'myapp-no-padding-dialog'})

If you can solve your style issues with the material 2 scss theming that would be the "right" way hears is a link to there site. https://material.angular.io/guide/theming.

However I used !important on the styles I didn't want materials styles to overwrite.

Here is how I used it:

/*hack to get rid of a scrollbar*/
.cdk-focus-trap-content{
    overflow-x: hidden !important;
}

/*hack to get rid of a padding on the popup*/
.mat-dialog-container{
     padding: 0px !important;
 }

I had a situation where a horizontal scroll bar was showing up in the md-sidenav and I got rid of their default padding on the md-dialog.

Not the most elegant solution but I hope this helps.

This is another StackOverflow question that discusses what !important is.

What does !important in CSS mean?

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

Try this:

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

You can also play with theming.
