- Popovers rely on the 3rd party library [Popper.js](https://popper.js.org) for positioning. You must include [popper.min.js](https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.8.1/popper.es5.min.js) before bootstrap.js in order for popovers to work!
- Popovers are opt-in for performance reasons, so **you must initialize them yourself**.
- Zero-length `title` and `content` values will never show a popover.
- Specify `container: 'body'` to avoid rendering problems in more complex components (like our input groups, button groups, etc).
- Triggering popovers on hidden elements will not work.
- Popovers for `.disabled` or `disabled` elements must be triggered on a wrapper element.
- When triggered from hyperlinks that span multiple lines, popovers will be centered. Use `white-space: nowrap;` on your `<a>`s to avoid this behavior.
When you have some styles on a parent element that interfere with a popover, you'll want to specify a custom `container` so that the popover's HTML appears within that element instead.

For proper cross-browser and cross-platform behavior, you must use the `<a>` tag, _not_ the `<button>` tag, and you also must include a [`tabindex`](https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/tabindex) attribute.

Reveals an element's popover. **Returns to the caller before the popover has actually been shown** (i.e. before the `shown.bs.popover` event occurs). This is considered a "manual" triggering of the popover. Popovers whose both title and content are zero-length are never displayed.
Hides an element's popover. **Returns to the caller before the popover has actually been hidden** (i.e. before the `hidden.bs.popover` event occurs). This is considered a "manual" triggering of the popover.
Toggles an element's popover. **Returns to the caller before the popover has actually been shown or hidden** (i.e. before the `shown.bs.popover` or `hidden.bs.popover` event occurs). This is considered a "manual" triggering of the popover.
Hides and destroys an element's popover. Popovers that use delegation (which are created using [the `selector` option](#options)) cannot be individually destroyed on descendant trigger elements.
