  • size="large": Sets the icon size to large.
  • color="secondary": Sets the icon color to secondary.
  • size="small": Sets the icon size to small.

Customizing Icons

You can customize the appearance of icons using CSS properties:

<ion-icon name="heart" style="color: red; font-size: 24px;"></ion-icon>

Explanation

  • style="color: red; font-size: 24px;": Sets the icon color to red and font size to 24px.
