Examples

Hover over the links below to see tooltips:

Placeholder text to demonstrate some inline links with tooltips. This is now just filler, no killer. Content placed here just to mimic the presence of real text. And all that just to give you an idea of how tooltips would look when used in real-world situations. So hopefully you've now seen how these tooltips on links can work in practice, once you use them on your own site or project.

Hover over the buttons below to see the four tooltips directions: top, right, bottom, and left. 

                  
                    <button type="button" class="btn btn-secondary" data-bs-toggle="tooltip" data-bs-placement="top" data-bs-title="Tooltip on top">
                      Tooltip on top
                    </button>
                    <button type="button" class="btn btn-secondary" data-bs-toggle="tooltip" data-bs-placement="right" data-bs-title="Tooltip on right">
                      Tooltip on right
                    </button>
                    <button type="button" class="btn btn-secondary" data-bs-toggle="tooltip" data-bs-placement="bottom" data-bs-title="Tooltip on bottom">
                      Tooltip on bottom
                    </button>
                    <button type="button" class="btn btn-secondary" data-bs-toggle="tooltip" data-bs-placement="left" data-bs-title="Tooltip on left">
                      Tooltip on left
                    </button>

And with custom HTML added:

                  
                    <button type="button" class="btn btn-secondary" data-bs-toggle="tooltip" data-bs-html="true" data-bs-title="<em>Tooltip</em> <u>with</u> <b>HTML</b>">
                    Tooltip with HTML
                  </button>

Usage

The tooltip plugin generates content and markup on demand, and by default places tooltips after their trigger element.

Trigger the tooltip via JavaScript:

                  
                    const exampleEl = document.getElementById('example')
const tooltip = new bootstrap.Tooltip(exampleEl, options)
Markup

The required markup for a tooltip is only a data attribute and title on the HTML element you wish to have a tooltip. The generated markup of a tooltip is rather simple, though it does require a position (by default, set to top by the plugin).

Making tooltips work for keyboard and assistive technology users

You should only add tooltips to HTML elements that are traditionally keyboard-focusable and interactive (such as links or form controls). Although arbitrary HTML elements (such as <span>s) can be made focusable by adding the tabindex="0" attribute, this will add potentially annoying and confusing tab stops on non-interactive elements for keyboard users. In addition, most assistive technologies currently do not announce the tooltip in this situation. 

                  
                    <!-- HTML to write -->
                    <a href="#" data-bs-toggle="tooltip" data-bs-title="Some tooltip text!">Hover over me</a>

                    <!-- Generated markup by the plugin -->
                    <div class="tooltip bs-tooltip-auto" role="tooltip">
                      <div class="tooltip-arrow"></div>
                      <div class="tooltip-inner">
                        Some tooltip text!
                      </div>
                    </div>
