How To Add Border-radius To Ion-img In Ionic 4

I need to add border-radius to ion-img but it seems shadow DOM won't let me modify. HTML CSS ion-img { border-radi

Solution 1:

The correct, non-obvious, way to do this is with CSS shadow parts.

In this case ion-img has a shadow part image so our SCSS looks like:

ion-img::part(image) {
  border-radius: 10px;
}

Yes, the part has no quotes and is the full word "image" (not "img" we need the part name, not the target tag name).

Solution 2:

HTML

<ion-img [src]="img-url"class="your-img"></ion-img>

CSS

.your-img {
    border-radius: 10px!important;
    overflow: hidden;
}

Solution 3:

1. put the image inside of card

<ion-card><ion-imgsrc="imag"></ion-img></ion-card>

2. after that set the style of the image

3. set image with and heigth to 100% in ion-img style

4. modify the value of radius in the ion-card component

Solution 4:

You can use:

<ion-avatar><ion-img [src]="item.image"></ion-img></ion-avatar>`

ion-avatar {
    --border-radius: 10px;
}

It's tricky to encapsulate style with Shadow DOM, but there are ways.

In this case, does it work for you with an inline style attribute?

<ion-img [src]="img-url" [alt]="alt" [style]="border-radius: 10px;"></ion-img>

Otherwise you might try adding a <style></style> tag to the inner HTML of the Shadow DOM with the border radius.

A modified example from the attached link:

const host = document.getElementById('shadow-host');

host.shadowRoot.innerHTML = `
<style>
  img {
    border-radius: 10px;
  }
</style>
`
