# bootstrapFontAwesome

> FullCalendar v4 documentation, for an old release. Web version: https://legacy.fullcalendar.io/v4/bootstrapFontAwesome

> Upgrading to v7: https://fullcalendar.io/docs/upgrading-from-v6.md

Determines which icons are displayed in buttons of the header/footer when Bootstrap 4 theming is on.

<div class='spec' markdown='1'>
Object, *default:*

```js
{
  close: 'fa-times',
  prev: 'fa-chevron-left',
  next: 'fa-chevron-right',
  prevYear: 'fa-angle-double-left',
  nextYear: 'fa-angle-double-right'
}
```
</div>

This option only applies to calendars that have [themeSystem](https://legacy.fullcalendar.io/v4/themeSystem.md) set to `'bootstrap'`. A FontAwesome stylesheet must be loaded before you can use Bootstrap 4 theming or customize the icons. [Getting started with FontAwesome](https://fontawesome.com/get-started).

A hash must be supplied that maps button names (from the [header](https://legacy.fullcalendar.io/v4/header.md)) to icon strings. [See a full list of FontAwesome icons](https://fontawesome.com/icons).

If a button does not have an entry, it falls back to using [buttonText](https://legacy.fullcalendar.io/v4/buttonText.md).

If you are using a Bootstrap theme and would prefer not to display any icons and would rather use `buttonText` instead, you can set the `bootstrapFontAwesome` option to `false`.
