Overriding Angular Material Size and Styling of md-dialog-container

Question

I am using Angular Material and I am using md-dialog for my popups for my gallery. The default animation and styling looks nice. However, I would like to change the width and height of size of the md-dialog-container? which is hidden. Only added when I click the modal and when you open the chrome dev tools you can see the md-dialog-container appearing. Do include how to override the rest of the styling.

Much appreciate with some help. Thanks.

Answer 1

From the official documentation:

Styling overlay components

Overlay-based components have a panelClass property (or similar) that can be used to target the overlay pane.

You can override the default dialog container styles by adding a css class in your global styles.css. For example:

.custom-dialog-container .mat-dialog-container {
    /* add your styles */
}

After that, you'll need to providies you css class as a panelClass parameter to your dialog:

this.dialog.open(MyDialogComponent, { panelClass: 'custom-dialog-container' })

Read this official documentation for more information.

Answer 2

There is no need to add global styles.

You can add this to your own component style:

::ng-deep .my-custom-dialog-class {
  mat-dialog-container {
    padding: 0;
  }
}

Make sure there is no "." (dot class selector) for mat-dialog-container because you must use the html tag selector.

Then when you open the dialog, add your class in panelClass property:

this.dialog.open(MyDialogComponent, {
  data: {},
  panelClass: 'my-custom-dialog-class'
});

By using a custom panelClass, this ensures only dialogs opened with that class will be affected, even using ng::deep.

Answer 3

You can change width/height of the modal by setting the values in the open() method, something like the following:

this.dialog.open(MyDialogComponent, {
  height: '300px'
  width: '400px'
});

Answer 4

    const dialogRef = this.dialog.open(WorkModalComponent, {
       width: '1200px',
       data: workObj,
       panelClass: 'my-dialog-container-class' // Replace with your actual dialog container class
    });

add the panelClass to your Dialog and add your CSS style to this class.
