    await modal.present();
    modal.onDidDismiss().then(res => {
      console.log(JSON.stringify(res))
      this.isModalDismiss = res.data.isDismiss;
      console.log(this.isModalDismiss)

Hi there,

Thanks for the issue. I can confirm that this is a bug. It looks like ion-modal does accept a --background CSS variable, but if you are using components like ion-header and ion-content you would never see it since those default to white backgrounds.

A temporary workaround would be to set the --background CSS variable for ion-content to transparent in addition to setting the --background CSS variable for ion-modal.

We will look into a solution for this. Thanks!

hi @liamdebeasi workaround is also not working

Você consegue resolver colocando no arquivo global.scss .modal-transparency { --background: var(--ion-background-color, rgba(0, 0, 0, 0.2)) !important ; }

@AshishSanu Going off what @gminhaneli and @liamdebeasi is proposing, here is a temporary solution.

To produce solution:

• generate a page for the modal ionic g page <PAGE NAME>
• import the page module into app.module.ts and include it in the list of imports
• Define a css class that will be used on ion-modal. This can be placed in variables.scss or global.scss(show below under CSS Class). --background is a css property and you will need to change it.
• import the page into the .ts where the modal will be present
• Include the class name you defined in cssClass property (show below under Function). cssClass is a property of ion-modal
• include a button in the .html file that will present the modal. Have that button call the function that presents the modal.

CSS Class

modal-transparency { 
  --background: transparent; 
  --height: 80%;

 // ion-toolbar {
 //   --background: transparent;
 //   color: white;
 // }
 // ion-content {
 //   --background: transparent;
 // }
}

Function

async confirm(){
  const modal = await this.modalCtrl.create({
    component: ModalPage,
    cssClass: 'modal-transparency'
    // componentProps: {value : "test"},
  });
  await modal.present();
  modal.onDidDismiss().then(res => {
    console.log(JSON.stringify(res))
    this.isModalDismiss = res.data.isDismiss;
    console.log(this.isModalDismiss)
    this.routeDriver();
  });
}

Hope this helps.

@codeherk @gminhaneli thanks for the response, I tried this but it isn't working

[codeherk]

I followed the steps I provided and copied your modal.html..

Only thing I did not copy was your modal.scss. You did not include the styling for circle and modal-content, so I ignored it altogether.

Here is a screenshot with the stylings from modal.scss applied.

The div that has the overlay class has a fixed position and it is applied directly over the content, covering the whole screen.

to have a good transparent (ionic 4), I made this 1) - modal.scss { ion-content { --ion-background-color : transparent !important; }' 2) - global.scss { modal-transparency { --background: transparent!important } 3) - and I call modal like this async confirm(){ const modal = await this.modalCtrl.create({ ... cssClass: 'modal-transparency' ... });

I hope it can help u.
