ion-toggle

Toggles change the state of a single option. Toggles can be switched on or off by pressing or swiping them. They can also be checked programmatically by setting the checked property.

Customization

Customizing Background

The background of the toggle track and handle can be customized using CSS variables. There are also variables for setting the background differently when the toggle is checked.

ion-toggle {
  --background: #000;
  --background-checked: #7a49a5;

  --handle-background: #7a49a5;
  --handle-background-checked: #000;
}

Because these variables set the background property, which is a shorthand, it can accept any value that the background property accepts.

A more complex case may involve adding an image to the handle background.

ion-toggle {
  --handle-background-checked: #fff url(/assets/power-icon.png) no-repeat center / contain;
}

Taking it a step further, we could use the ::before or ::after pseudo-elements to position text on top of the background.

ion-toggle::before {
  position: absolute;

  top: 16px;
  left: 10px;

  content: 'ON';

  color: white;
  font-size: 8px;

  z-index: 1;
}

Customizing Width

Adjusting the width of the toggle smaller will result in a narrower track, with the handle remaining the default width. If desired, set --handle-width to make the handle narrower.

ion-toggle {
  width: 40px;
}

Adjusting the width of the toggle larger will result in a wider track, with the handle remaining the default width. If desired, set --handle-width to make the handle wider.

ion-toggle {
  width: 100px;
}

Customizing Height

Adjusting the height of the toggle smaller than the default will result in the handle height auto-sizing itself to the track. In ios the handle is shorter than the track (100% - 4px) and in md the handle is taller than the track (100% + 6px).

ion-toggle {
  height: 15px;
}

Note: this does not affect the handle width, width should be set using --handle-width.

Adjusting the height of the toggle larger will keep the handle in the center at the default height. This can be modified by setting --handle-height which can be set to any amount but will not exceed the --handle-max-height.

ion-toggle {
  height: 60px;
}

Note: this does not affect the handle width, width should be set using --handle-width.

Customizing Spacing

The spacing refers to the horizontal gap between the handle and the track. By default, the handle has 2px of spacing around it in ios only. In md mode there is no default spacing.

To remove the horizontal spacing, set --handle-spacing to 0px.

ion-toggle {
  --handle-spacing: 0px;
}

Due to the handle having a fixed height, to remove the spacing on the top and bottom, set the height to 100%.

ion-toggle {
  --handle-spacing: 0px;
  --handle-height: 100%;
}

Customizing Border Radius

The --handle-border-radius can be used to change the border-radius on the handle.

ion-toggle {
  --handle-border-radius: 14px 4px 4px 14px;
}

To target the border-radius only when the toggle is checked, target .toggle-checked:

ion-toggle.toggle-checked {
  --handle-border-radius: 4px 14px 14px 4px;
}

Customizing Box Shadow

The --handle-box-shadow can be used to change the box-shadow on the handle.

ion-toggle {
  --handle-box-shadow: 4px 0 2px 0 red;
}

To target the box shadow only when the toggle is checked, target .toggle-checked:

ion-toggle.toggle-checked {
  --handle-box-shadow: -4px 0 2px 0 red;
}

See the section on customizing overflow to allow the box-shadow to overflow the toggle container.

Customizing Overflow

Setting overflow on the toggle will be inherited by the toggle handle. By default, overflow is set to hidden in ios only. The box-shadow will still appear cut off due to the contain css property. Set contain to none in order to overflow the toggle container.

ion-toggle {
  --handle-box-shadow: 0 3px 12px rgba(255, 0, 0, 0.6), 0 3px 1px rgba(50, 70, 255, 0.6);

  overflow: visible;

  contain: none;
}
