Add small overlays of content, like those on the iPad, to any element for housing secondary information.
-Popovers whose both title and content are zero-length are never displayed.
- -Popovers require the tooltip plugin to be included in your version of Bootstrap.
-For performance reasons, the Tooltip and Popover data-apis are opt-in, meaning you must initialize them yourself.
-One way to initialize all popovers on a page would be to select them by their data-toggle attribute:
When using popovers on elements within a .btn-group or an .input-group, you'll have to specify the option container: 'body' (documented below) to avoid unwanted side effects (such as the element growing wider and/or losing its rounded corners when the popover is triggered).
To add a popover to a disabled or .disabled element, put the element inside of a <div> and apply the popover to that <div> instead.
Sometimes you want to add a popover to a hyperlink that wraps multiple lines. The default behavior of the popover plugin is to center it horizontally and vertically. Add white-space: nowrap; to your anchors to avoid this.
Four options are available: top, right, bottom, and left aligned.
-Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.
-Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.
-Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.
-Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.
-Use the focus trigger to dismiss popovers on the next click that the user makes.
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 attribute.
Enable popovers via JavaScript:
- {% highlight js %}$('#example').popover(options){% endhighlight %} - -Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-animation="".
