ion-button

shadow

Buttons provide a clickable element, which can be used in forms, or anywhere that needs simple, standard button functionality. They may display text, icons, or both. Buttons can be styled with several attributes to look a specific way.

Basic Usage

Expand

This property lets you specify how wide the button should be. By default, buttons have display: inline-block, but setting this property will change the button to a full-width element with display: block.

Shape

This property lets you specify the shape of the button. By default, buttons are rectangular with a small border radius, but setting this to "round" will change the button to a rounded element.

Fill

This property determines the background and border color of the button. By default, buttons have a solid background unless the button is inside of a toolbar, in which case it has a transparent background.

Size

This property specifies the size of the button. Setting this property will change the height and padding of a button.

Accessibility

Buttons are built to be accessible, but may need some adjustments depending on their content. The button component renders a native button element which allows it to take advantage of the functionality that a native button provides.

Overflowing Text Content

There are many cases where a button's text content may overflow the container. It is recommended to wrap the text inside of the button when this happens so that all of the text can still be read. The button component will automatically adjust its height to accommodate the extra lines of text.

The button text does not automatically wrap to the next line when the text is too long to fit. In order to make the text wrap, the ion-text-wrap class can be added, which will set the white-space property to "normal". This will become the default in a future major release.

info

The max-width style is set on the button below for demo purposes only. Text wrapping will work with a dynamic button width.
