-Pass an `aria_pressed` value (`'true'` or `'false'`) to enable a toggling button. If no `content_start_icon`/`content_end_icon` or `content_start`/`content_end` block content is passed in, the `'bell'` icon will be used by default as the `content_start_icon` value.
+To add a slash across the icon(s), use the `is-slashed` state modifier CSS class.

+If no `content_start_icon`/`content_end_icon` or `content_start`/`content_end` block content is passed in, the `'bell'` icon will be used by default as the `content_start_icon` value.
