Disable Scrolling for a Mat Dialog in the backdrop
Am trying to disable page scrolling when Mat Dialog is opened . Tried overflow:hidden but it didn't work . 
dialogConfig = new MatDialogConfig();
dialogConfig.autoFocus = true;
dialogConfig.backdropClass = "backdropBackground";
dialogConfig.hasBackdrop = true;
dialogConfig.panelClass = "custom-dialog-container";
const dialogRef = this.dialog.open(ModalComponent, dialogConfig);
style.css:
.backdropBackground {
background-color: rgba(0, 0, 0, 0.61);
overflow: hidden;
}
dialogConfig = new MatDialogConfig();
dialogConfig.autoFocus = true;
dialogConfig.backdropClass = "backdropBackground";
dialogConfig.hasBackdrop = true;
dialogConfig.panelClass = "custom-dialog-container";
const dialogRef = this.dialog.open(ModalComponent, dialogConfig);
style.css:
.backdropBackground {
background-color: rgba(0, 0, 0, 0.61);
overflow: hidden;
}

The scrolling element needs to have
overflow: hidden. You can check the scrolling element with document.scrollingElement (JS). It is usually the <html>.
